It's already three years since the Jaguar Land Rover company stopped producing the Freelander 2 car - it was replaced by the new Discovery Sport. But cars are bought for more than one day, especially premium cars, which is Freelander.

Nevertheless, the "youngest" car from this family is now at least three years old - the age, of course, is not yet a mature man, but no longer a child. It's time to contact a specialized car service and check its "internal organs" - the engine and, first of all, the turbine.

Why a turbine? -

Yes, because both the engine power and its resource depend on the accuracy of the turbocharging system of a diesel engine. Even minor failures in the operation of the turbine (and all breakdowns begin with minor failures), if its operation is not "corrected" in the right direction in time, will lead to serious and costly breakdowns. Moreover, a faulty turbine can easily cause damage to other engine components. And repair, for example, of a cylinder-piston group, is, in fact, a major overhaul of the engine.

The first question that the owner of the car usually asks the service master is what is the price for repairing the Freelander 2 turbine. In response to this, an experienced specialist will only throw up his hands, they say, we will disassemble - we will see, and if we see - we will count.

But, even removing the turbine from the engine and disassembling it, as they say, "by the bones", the cause of the breakdown may not be found. Perhaps it lies only in the contamination of parts; possibly - in the ingress of a foreign object into the turbocharging system (this is found all the time); possibly - turbine imbalance; and it may also happen that some part is out of order.

Be that as it may, but the first

the turbine parts are sent for cleaning and rinsing. And only when they shine, like new ones, the master will examine them, "diagnose" and "prescribe treatment." , flushing and balancing will be sufficient.

All turbine components are made of high-alloy steels that can withstand high loads, high pressures, and high temperatures (namely, in such conditions the turbine has to work), so it is not so easy to break any of them. To do this, there must be a foreign object in the turbine - a small pebble flying out from under the wheel or even a grain of sand.

Where does a pebble come from in a turbine, if it is "packed" in a sealed casing? The fact of the matter is that a breakdown begins with a depressurization of the case: its rubber or plastic gaskets crack, break - and goodbye to tightness.

Now a few words about

how high is the price of spare parts for the Freelander 2 turbine and whether it has changed in connection with the withdrawal of this vehicle from production. Garrett turbochargers are installed on almost all diesels that Freelander 2 was equipped with throughout the entire production period of the car. Turbines of this brand are rightly considered one of the most reliable in the world and are installed not only on Land Rover.

The fact that the era of production of Discovery 2 is a thing of the past does not mean that Garrett has stopped producing the turbines that were put on the engines of these machines. Therefore, problems with finding spare parts for these turbines should not arise, and since 2013 the price for them has not changed. Of course, in dollar terms - after all, but Garrett is an American company and neither Garrett turbines nor spare parts for them are produced in Russia. At least officially. But we are talking about "native" spare parts for Freelander, and not about parts of dubious production and equally dubious quality.

Yes, in order to carry out a high-quality repair of the Freelander 2 turbine, the price will turn out to be rather big, but the machine itself is not cheap either.

However, this is how to count: turbines

Garrett, standing on Freelander 2 diesels, are distinguished not only by their impeccable quality of work, but also by a significantly longer resource than turbines from less famous manufacturers. So, if timely and regular preventive inspections and cleaning of turbines are carried out, it may not even come to repair with replacement of components.

There are two ways to clean a diesel engine turbine: without removing it from the engine and then disassembling it, and by washing each part separately. The first method is to pour a special cleaning fluid into the turbine. The only but significant drawback of this method is that it does not guarantee perfect cleaning performance.

The disadvantage of the second method is that after cleaning, it is possible to assemble and balance the turbine only under the conditions of a specialized car service - only there is everything necessary for carrying out this difficult procedure, the equipment, and the masters with the appropriate qualifications. But a complete cleaning of the turbine 100% guarantees the result. So from time to time, it makes sense for diesel owners to fork out for it.

I found a few days ago a drop of oil under the car, looked closely and saw that it was flowing from me .. not much but dripping .. I had to pour more liters of oil into the engine so that the level was in the middle of the mark on the dipstick.
considering that on January 1 (2 days later) a trip to Lapland is planned, immediately to the service in omega premium (spb)
The car was lifted with me on a lift, and without disassembling it without touching it even, seeing the stains, they said that it was the turbine that sucks oil and spits it out through the intercooler, that the turbine needs to be changed, possibly the intercooler.
the cost of the turbine was announced at 50,000 (taking into account a 10% discount), the cost of work is another 20,000.If the intercooler is changed, then the replacement with work is another 12,000
total: 70 - 80,000 rubles

if thoughts how can you reduce the amount? do you know where the turbine is cheaper? maybe it can be restored? etc.
I will be glad to all the reviews ..
if someone had something similar, write it down too ..

we are going to Finland in another car, a trip on this one is no longer considered. but the problem will remain upon return, and it will have to be solved ..
to be honest, I don’t want to give 70,000, I called for turbine repairs, they give a guarantee for work = 1 year (they also give a year for new turbines), plus they say that all spare parts for turbines they have are original .. and it costs all 12- RUB 18,000
I think I’ll go there ..
can anyone repair the turbine?

about a possible replacement of the turbocooler, they say that the plastic holders must have broken. although I think you can just rinse it ..

Well, just do all this, of course, it's strange .. you come to the dealer's office, and he puts you a diagnosis by eye.

The 2.2 TD turbocharged diesel engine was installed on the Freelander 2 from 2007 to 2015. Had 2 options - 150 hp. and 190 hp.

One of the malfunctions that we encountered on a 2.2 TD diesel engine was valve loosening and getting into the engine cylinder. Those. for some reason, the valve falls apart and falls directly into the cylinder, clogs the piston and scrapes the cylinder mirror. As a result of such serious blows, the cylinder head becomes unusable, a defect of the shorts of the block itself and possibly the crankshaft appears (microcracks, shift, displacement). In such cases, the easiest way is to purchase a used engine assembly and replace it, because the cost of a new shorts block, cylinder head is such that the cost of repair turns into a cosmic one. See here for more details.

One of the common malfunctions on a 2.2 TD engine is a rupture of the intercooler pipe on the intake manifold to the throttle assembly or a depressurization of the intercooler radiator itself. With this defect, the check-enjin icon lights up on the instrument panel. You can check the condition of the air pipe on your own, but a small "gap", crack, rupture cannot always be detected visually. Therefore, it is recommended to inspect the pipe on a running and gas engine, then the pipe from the turbo boost is inflated and the leak is easier to find. If during inspection you observe a leaking pipe (oil leakage), then it is recommended not to wait for it to rupture, but to change it in advance, the same applies to the intercooler radiator so that they do not unexpectedly let you down on the road. See here for more details.

This part is quite expensive, so we have developed an anti-crisis option. We assembled this branch pipe from several parts, selected the necessary branch pipes at a certain bend angle, a transition pipe and assembled an alternative branch pipe to the original. Its cost is half that of the original.Our observations have shown that these branch pipes serve for half a year and a year or more, and no problems have arisen with them.

Also, a common malfunction of this diesel engine is a malfunction of the throttle assembly (throttle valve). This throttle assembly with an electrically controlled damper cannot be repaired and is replaced as an assembly. Typical symptoms indicating a malfunction of the throttle unit are poor engine start, the diesel engine stalls, sometimes it works intermittently, after stopping the engine does not stall immediately, but begins to "sneeze", or after stopping the engine, "clanging" of a metal or plastic nature is heard ... If, when reading fault codes using special computer equipment, codes indicating the throttle assembly are found, then it must be stupidly changed - sometimes there are options for faulty wiring suitable for the throttle assembly, but they are very rare in practice. See here and here for more details.

Another 2.2 TD engine malfunction, in which the CHECK YENJIN indicator lights up, may be the result of a malfunction of the EGR valve, the exhaust gas recirculation system. Symptoms of a EGR valve malfunction are a weakening of power, increased smoke when the engine is running, increased fuel consumption, and uneven engine operation. An accurate diagnosis of the need to replace the USR valve is possible only when carrying out computer diagnostics on special equipment for the Land Rover. It should be understood that replacing the EGR valve on a 2.2 TD diesel engine is advisable when assembled with an EGR cooler.

Another common malfunction in a 2.2 TD diesel engine is engine overheating due to clogged radiators in the engine cooling system. The fact is that over time, the oncoming dust, together with the fluff, is clogged up by the oncoming flow of oncoming air in the honeycomb of the engine cooling radiators. the cooling and air conditioning radiators are located one after the other in a "sandwich" close to each other. In addition, an intercooler radiator is also installed on this engine. Over time, as a rule, on runs over 80,000 km, and sometimes even earlier, compacted dust accumulates between these radiators, similar to dense felt. For this reason, the radiators are not fully blown by the air flow. The engine management system, based on the readings of the temperature sensors, detecting engine overheating, turns on the electric cooling fans at full capacity and makes them work without interruption. In such modes, the fans often overheat (or rather, the control module overheats) and fails, and it happens that the connector of thick fan power wires melts. Therefore, at the first symptoms of engine overheating, it is necessary not to aggravate the situation and flush the engine cooling radiators with their complete dismantling.

The first symptoms of engine overheating:

temperature readings are higher than usual;
the air conditioner is turned off (climate control);
the fan makes a loud noise and runs constantly.

As a rule, problems with overheating begin with the onset of summer and the first hot days. As a result of such constant overheating, the block of cooling electric fans, working at full capacity for a long time, fails. Separately, the control module from the entire fan block is not defective (not sold), so you have to replace the entire fan block assembly. According to some customers, they found used fans during disassembly and replaced them with their units - this is the only way out that can be done on a budget. The practice of repairing the blocks themselves has not been revealed.

Also on the 2.2 TD engine, there is an oil leak at the bottom of the engine. Based on service practice, oil most often flows from the joint between the automatic transmission and the engine (through the automatic transmission oil seal or the engine crankshaft), as well as from under the seals of the engine pallet and the bed (skirt) of the diesel engine short block.

If oil flows out of the joint between the engine and the automatic transmission, then first of all it is necessary to understand which oil is flowing - automatic transmission oil or engine oil. The diesel engine oil has a black tint, the automatic transmission oil is lighter. In any case, if an oil leak is detected at the junction of the automatic transmission and the engine, the automatic transmission oil seal and the rear oil seal of the engine crankshaft will need to be replaced; this will require dismantling the automatic transmission.

If, when inspecting the lower part of a diesel engine, there are oil leaks, then, as a rule, oil leaks from under the sump seal or bed (skirt) of the engine block, or which often happens here and there. Structurally, the 2.2 TD diesel engine has a distinctive feature from many other engines, namely, the presence of balancing shafts! The balance shafts are mounted below the crankshaft and are driven by a gear located near the piston counterweight of the third cylinder. It is from them, or rather because of the need to lengthen the crankcase space, that an additional nozzle is structurally introduced, which is called a bed or skirt. And over time, from under it - from under the butt seal between the nozzle (bed) and the cylinder block, engine oil can leak. The only way out of this situation is to dismantle the nozzle and the pallet, clean the butt surface and re-seal both the nozzle and the pallet with a new sealant. In practice, it is advisable to change the pallet, because after dismantling, it tends to deform, and when re-installed it cannot always tightly cover the butt surface, despite the high-quality processing with a sealant. Again, this is not a divorce on a new pallet. And the accumulated service practice.

Another malfunction, which is rare, but occurs on a 2.2 TD diesel engine, is the destruction of the tip of the exhaust camshaft of the injection pump drive. As a rule, a client with this engine deals with the problem of the inability to start the internal combustion engine. That is, the starter turns, but the engine does not start. LR-WEST service specialists had to meet with the destruction of the exhaust camshaft (the tip of the injection pump drive) more than once. And when in our service they encounter this malfunction, then already in advance, having a proven practice, it is envisaged to eliminate all the consequences and the very causes of this defect. The procedure for replacing the camshaft entails the removal of the fuel injectors, all fuel lines, the EGR valve, the oil separator, the intake manifold, which in turn necessitates the replacement of all gaskets (which are essentially disposable) and other disposable fasteners. Well, reinstallation or replacement of a set of attachment belts and timing belts, at the request of the client, depending on the mileage and when the last time he changed the timing belt. See here for more details.

All these and many other nuances about the 2.2 TD turbocharged diesel engine should be known, and the LR-WEST service specialists know them and constantly monitor the latest reports from Land Rover engineers. LR-WEST service specialists have 7 to 16 years of experience in engine repair. On average, about 300 major and medium engine overhauls are carried out in our technical center.

All repair and diagnostic processes of the LR-WEST service are carried out in strict accordance with the requirements of the Jaguar Land Rover manufacturer. We give a 1 year warranty for the work performed and spare parts with no mileage limitation!

The video briefly tells about a turbocharger on a diesel Freelander 2, with a 2.2 TD engine. A similar engine is installed on Discovery Sport and Range Rover EVOK.

Video Turbine Land Rover Freelander 2- features and malfunctions. channel LR West

An integral part of absolutely any car, including the Land Rover Freelander 2 SUV, is an excellent quality turbine, the purpose of which is to purposefully increase the amount of vehicle horsepower. Carrying out regular inspections immediately contributes to a significant and significant increase in the life of the part, which ultimately will help to maintain the operation of the engine as a whole at a qualitative level.

The need to replace a turbine on a Land Rover Freelander 2 arises only when it is completely unusable for its intended purpose.

LRservice technical center specialists highlight some distinctive features and nuances, which will notify the car owner about the presence of some problems:

a rapid increase in oil consumption;
some leakage of original oil from such important places as a turbocharger or a branch pipe;
increased fuel consumption;
a decrease in the power indicator of an excellent power unit;
the presence of problems in the dynamics of acceleration;
the appearance of noises of unknown origin in the operation of the engine;
comparatively high index of exhaust smoke.

If you even notice one of the above signs of a turbine breakdown, then the best solution would be to contact a qualified LRservice service, where our specialists in an optimally short period of time will perform all the necessary set of diagnostic measures and carry out a high-quality repair of the Land Rover Freelander 2 turbine.

Maintenance and repair of a Land Rover turbocharger is a very complex and time-consuming technological process that requires highly specialized equipment and proper experience in the implementation of work. At the most affordable price, a turbine for the Land Rover Freelander 2 can be purchased at the LRservice technical center.

In the overwhelming majority of cases, the implementation of repair manipulations is not possible, therefore, in the future, there is an urgent need to replace the Freelander 2 turbine.

The procedure itself includes several clearly defined stages:

complete dismantling of a unit that has become unusable;
installation of a completely new turbocharger with optimally tight replacement of all disposable seals and consumables;
implementation of a set of measures to check the good condition of the installed system.

It is possible to buy a turbine for Land Rover Freelander 2 in an optimally short period of time. To do this, you just need to contact the LRservice technical center, it is also possible to get acquainted with the information presented on our website.

The LRservice technical center has a relatively considerable experience in the implementation of work in this direction.

For a high-quality implementation of the problem of repairing a turbine on Freelander 2, qualified craftsmen use absolutely new modern spare parts in practice. A fairly long warranty period is provided for the entire range of services provided.

Turbine failure is a common cause of engine malfunction. Moreover, a malfunction of the indicated device is often associated with the following reasons:

malfunction of the impeller bearing;
failure of the executive inflation control.

As a rule, such malfunctions are caused by acidification of the drive levers, caused by a long idle time of the car and, as a rule, end with the replacement of the turbine with a Freelander 2, which is quite unpleasant.

Another cause of turbine malfunction is the loss of the retaining ring from the actuator arm. In this case, the problem of repairing a turbine on Freelander 2 is solved quite simply - a banal replacement of a lost element.

The LR CENTRUM service center offers its services for the repair of the turbine on the Freelander 2, as well as its replacement, and guarantees fast and high-quality work at any time convenient for the customer.

The second generation Land Rover Freelander began production in 2006. In 2012, a restyling was carried out, which resulted in visual changes to the interior and exterior elements, minor structural improvements and an expansion of the range of installed engines. The production of this car continues to this day.

Diesel engines were equipped with classic turbochargers. Range Rover Evoke and Land Rover Discovery Sport cars were equipped with similar turbines.

A turbocharger consists of two chambers called a hot and cold snail. These chambers are connected through an intermediate block called a cartridge. The cartridge contains bearings in which the rotor shaft rotates.

Two impellers are fixed at the ends of the rotor shaft. One of them is located in the hot part of the turbine and is driven by the flow of exhaust gases. The second is installed in the cold part of the turbocharger housing. It serves to pressurize the intake manifold. The system has an intercooler designed to cool the air supplied to the cylinders.

There is a variable geometry mechanism to control the pressure generated by the turbine. The geometry is controlled by an electronic actuator.

Exhaust gases, passing through the vanes of the geometry mechanism, enter the hot impeller and spin it up. Rotation is transferred through the rotor to the cold impeller, which builds pressure into the intake manifold. By increasing the volume of supplied air, the engine power is increased.

The turbine is an expensive component in a car. This is due to the fact that it works in extremely difficult conditions. High temperatures, the highest rotational speeds that can only be found in a car structure, and an aggressive environment force manufacturers to use high-strength heat-resistant materials in the turbine design. Manufacturing is carried out with increased precision.

Therefore, the price for the repair of the freelander 2 turbine is also high. It is impossible to talk about exact figures in the price of repairs, since this value is variable and varies depending on several factors:

the price of new or contracted components;
the degree of damage;
the complexity of the restoration work.

You can make a rough list of the cost of repairing each of the turbocharger parts in descending order:

cartridge;
actuator;
turbine geometry and its drive;
impellers;
body parts.

It should be borne in mind that sometimes a turbocharger has so many damage that it is impractical to repair it. It is cheaper and easier to purchase a new turbine or any of its assembly units (for example, often repairing a cartridge, taking into account the price of spare parts and the cost of work, will cost more than buying a new one).

In general, the turbine on the Land Rover Freelander 2 is well designed. The reliability of its work, especially the mechanical part, is above average. If all operating conditions are met, the turbocharger can operate up to 200 thousand kilometers without problems. Only after this mark will the first serious malfunctions appear.

Consider the main signs of a failing turbine:

floating or reduced engine power;
uncharacteristic noise or whistle that the turbine emits during its operation;
metal extraneous sounds, grinding or knocking from the side of the turbine, especially noticeable when the load on the engine changes;
increased oil consumption;
increased smokiness;
engine error.

This is just a list of the main signs that may indicate a failing turbine.

All these symptoms are manifested in the following malfunctions:

production in the bearing unit;
violation of the tightness of the seals of the bearing assembly;
destruction of impeller blades;
jamming of the geometry change mechanism;
malfunction of the electronic actuator or the kinematic connection of the geometry control;
cracks in the turbine casing;
abundant blockages of working cavities.

Initial diagnostics are performed on a running engine. First, the operation of the turbine is monitored at various engine operating modes. The performance of the electronic actuator is visually assessed. The external condition of the turbine body parts is examined for cracks and oil leaks. The presence of damage to the case is a non-repairable malfunction and can only be eliminated by replacing it.

A computer is connected to the diagnostic connector. The error log is read. The operating parameters of the turbocharger are viewed in real time.

If the initial diagnostics showed that there are malfunctions or suspicions of them, then the turbocharger is dismantled. To do this, disconnect all the pipes (air and oil) and the actuator wire chip. The front exhaust pipe is disconnected. The support bracket and the nuts securing to the exhaust manifold are unscrewed. The turbine is removed from the engine.

Further diagnostics are carried out in parallel with disassembly. The stem cotter pin is removed from the side of the electronic actuator, and the actuator is removed. The evaluation of the backlash in the kinematic connection of the turbine geometry control is carried out. If there are excessive backlashes, repair or replacement is performed (depending on the degree of damage).

The electronic actuator is tested at a specialized stand. It must act on the rod with a regulated force and speed. In most cases, an electronic actuator cannot be repaired. However, sometimes it can be restored to working capacity if there is no critical damage.

The screws securing the snails are unscrewed. The hot snail is disconnected. The condition of the inner surface is examined. In case of contamination, cleaning is performed. The integrity of the blades of the hot impeller is checked. If there is damage, it is replaced, since the impeller is not a repairable part.

The state of the geometry is assessed. Its performance is checked. In most cases, thorough cleaning in an ultrasonic bath is sufficient to restore the working condition of the wedging geometry.

The cold snail is detached. The condition of the impeller and the working surface of the housing is examined. If damaged, it will be replaced.

The free play of the rotor shaft is evaluated. If there are increased backlashes or oil leaks, the cartridge is disassembled. After disassembly, the condition of the internal cavity is examined. If there is damage on the seating surfaces of the cartridge body, it is replaced with a new one. If there is no critical damage, repair is possible.

The condition of the rotor shaft is inspected. Particular attention is paid to the surfaces in contact with the bearings. If you have small workings, you can grind the shaft. If the output is higher than the permissible rate, then the shaft is considered unsuitable for further operation.

Bearings and seals must be changed, even if these elements are not very worn out.Their cost is negligible compared to the cost of dismantling and disassembling the turbine, so if it comes to disassembling the cartridge, it will be advisable to change these elements.

After replacing the inner parts of the cartridge, the rotor shaft is centered. This procedure is performed on a specialized stand designed exclusively for balancing turbines. This procedure is mandatory for all repaired turbochargers. Even a slight deviation of the center of gravity of the impeller shaft from the axis of rotation will lead to accelerated wear of the bearings and the shaft itself due to the generated runout.

After alignment, the turbocharger is assembled and installed on the vehicle. A control check of its operability is carried out at different operating modes of the engine. The turbine operating parameters are read from the electronic control unit, and the readings from the intake manifold pressure sensor are evaluated.
