DIY repair citroen c4 sedan

The Citroen C4 car was first seen in 2004, and it was not in vain, because to this day this car still meets the declared reliability and safety indicators compared to other cars of the same class. At first, relatively inconspicuous, with each new version of the Citroen C4 it began to contain more and more new functions. The latest versions of the car are thoroughly "stuffed" with various electronics, which sometimes helps out, but sometimes it rubs the nerves, and then it becomes necessary to repair the Citroen C4. But first things first.

Note that repair Citroen, or rather its need, in some moments depends on the vehicle configuration. So, the following versions are included in the line of this "Frenchman":

• Classique
• Confort
• Exclusive - variation for the hatchback
• VTR, VTR + and VTR Pack - Coupé variation

As for the correct choice of the model, this is up to everyone personally. Repair of the Citroen C4 Picasso after the operation period may be needed in the same way as the Citroen C4 Cactus. Therefore, the point is not so much in the principled choice of the model and configuration, but in the knowledge of the weak points of the car, which, in turn, must sometimes be paid attention to.

I would like to note in advance that, in general, the Citroen C4 is a prominent car with excellent characteristics both for driving in urban areas and beyond. But in this article we will pay more attention not to the advantages of the model, but to the disadvantages, so that potential buyers can see the full picture of the technical capabilities of the machine.

So, repair of Citroen C4 is very often associated with automatic transmission malfunctions. Sometimes it stops holding the valve, sometimes the entire valve body fails, and it also happens that the band brake completely breaks off, as a result, the box just wedges. No matter how hard manufacturers struggle with this problem, they cannot fully solve it. Therefore, fans of the C4 model often wisely choose the "mechanics".

Sometimes it is required to visit the Citroen C4 car service in St. Petersburg due to the failure of the electric seat heating system. The biggest boom in this problem occurred in 2008. However, not often, but from time to time, this defect occurs in new models. This is due to the interconnected elements of the back and cushion system. Therefore, when at least one posting is frayed, the entire system stops working.

The rest of the breakdowns, due to which it is necessary to service the Citroen C4, include periodic disconnection of the engine temperature sensor, frequent malfunctions of the headlight washers. And with the generator, mainly due to the effects of chemistry, which the road services scatter on the roads, fighting the ice, problems begin in three or four years.

And the car, of course, is beautiful, the designers did their best. But you will not be full of beauty alone, so do not forget to provide timely maintenance of the Citroen C4, and periodically look at the nodes prone to weaknesses.

It was like this .... I drove the next 20 tyrs, I think it's time to do something, the guarantee ended a week ago, until OD-1500 km, in short I ordered through> consumables, the day was warm today -5 in total and I got down to business on the street near the house. The experience of substitutions has already been. I used to hold a Frenchman and the filters had to be changed. Russian roads, whatever they say, is the most dangerous roads in the world ... You don't know where a stone will fly to you or a traffic cop will jump out of the bushes.

So, I started with the cabin filter, behind this Shumkov.

there is such a hatch:

We pull it more boldly, open it and take out the filter. As you can see, the filter turned out to be crumpled, they shoved it at the OD and FSUs, but I think it’s so dusty in the cabin!

We carefully insert the new one so that it properly closes the intake, you can visually check, the hatch is in place, the Shumka is in place.

Now the air filter, here of course it is more difficult, at first I was worn out, how to unscrew the distant screw

BUT I went the wrong way, the filter must be removed entirely, but I wanted to open it in place, we remove the battery, I threw out the casing from it for a long time, so it’s not long to remove it, the air intake is also removed for a short time, twist the corrugation clockwise and pull it out, and he himself is simply attached to the latch:

We also unscrew the tank with the brake, now the access is better, unscrew the bolt holding the filter housing:

disconnect the air vent by clicking on the "yellow":

it does not hold anything else, we carefully take it out and open it without steaming, I brought it home, cleaned it of the sand, inserted a new filter.

Now the candles, remove the cover from the engine (6 screws), disconnect the air ducts by pressing the "yellow" button, so as not to interfere

unscrew the block with candle caps (4 screws), take out this block

we take a candlestick and unscrew the candles (I broke one key, took a reinforced one, they were tightened conscientiously!)

The candles, in principle, are workers (passed 36,000) - they have a coffee color (let's leave it, they will suddenly come in handy!)

And now everything is in reverse order, without hurrying, with feeling, with proper arrangement!

I still have the front brake pads (I also think I'll replace it myself), I decided to try "TEXTAR", tk. my relatives creak terribly, these I can say at random, but I hope for the best, the firm seems to be normal and there are also rubber bands for the brushes (not native, but suitable), I will change them closer to spring, now I don’t see the point:

and if anyone is interested here is the invoice for spare parts (prices 2008):

oil, I went and replaced it at the station, I was reluctant to take off the armor, they sucked it for 200 r, to unscrew the oil filter you need a head on "27", now everything seems to be ... Maybe someone will come in handy!

TOTAL DEPENDENCE (Oil change)!

We change the air filter: after releasing the retainer, we pull up the plastic resonator of the air duct, simultaneously removing the corrugation from it. We unscrew the bolt securing the filter housing and loosen the pipe clamp on the throttle assembly. Now we remove the brake reservoir, turned out a couple of self-tapping screws under - Torks-20, and take it to the side.

Shaking the body up and down, we move the pipe from the throttle assembly and take out the body. We turn out the self-tapping screws around the perimeter and, after removing the cover, we change the element. When assembling, make sure that the branch pipe is firmly seated on the throttle assembly!

To replace the spark plugs, unscrew the six self-tapping screws of the engine decorative lining and four bolts of the ignition modules. Remove the crankcase ventilation hoses by pressing on the yellow tip clamps. Raising the module so that the tips come out of the candle wells, we lay it across the valve cover - in this position it does not block access and is held on the wiring (the plug was not disconnected). Candles - turnkey for 16 ".

There is an automatic machine in the drive of the Attached Aggregates, which is great - you can't go wrong with the belt tension!
For a timing belt, about the same device, but semi-automatic. To set it in working condition, it is necessary to combine the arrow on the moving sector with the front sight on the stationary one. If you had to change a belt with a similar drive pattern, there will be no difficulties. Another thing, according to the French tradition, in the pulley-crankshaft connection, there is not a single dowel pin. That is, by unscrewing the central bolt, you can endlessly select the correct position of the shaft with the pulley. Here you cannot do without mandrels! There is nothing special in them: drills are also suitable for fixing the camshafts, and a more or less experienced car mechanic can make a hook for the crankshaft from a 6 mm bar. But it is better to entrust this work to specialists.

At the same time, let them change the rear pads - here you need devices for screwing in pistons, which not everyone has. Moreover, in the mechanisms of the "Bosch" company (they were installed until 2006), the pistons have to be turned in different directions, which means that two devices will be required - with a right thread and with a left one. It is easier with the front pads, it is only important to orient them correctly: the bevel of the lining should be on top. Of course, do not forget to clean the assembly from wear products and lubricate. And change the guide bolts - they, with locking sealant on the thread, are supplied in the original kit.

At first glance, changing bulbs in headlights is not difficult. It seems that the access is normal, and it is easy to remove the rubber plugs of the case. This is confusing: when a headlight lamp burns out, the owner takes over. It was not so! The block sits so tightly that the efforts of the fingers are simply not enough, and it is not possible to stick a brush in order to grip it tighter - the opening is not enough. I just want to pull off the connector with pliers. Take your time - you can easily pull out the landing sleeve on the reflector by the roots. It is better to make the simplest device: we bend a strip of steel 1.5x10x150 mm in the shape of a hook, sharpening the tip on emery under a wedge. We push it into the gap between the block and the lamp and, shaking and moving the mandrel around the perimeter of the block, gradually move it from the lamp. And to understand the principle of fixing the lamp, we use a mirror.

With front foglights, the same problem as with many other cars: there is a lot of dirt in the work area. In addition, here you need to remove the bumper skirt - unscrew seven bolts for "Torks-20", three under the key "for 10" and also squeeze out a couple of latches. It is extremely inconvenient to work without a lift.
We remove lanterns to replace lamps - such is, sadly enough, the current trend. Having removed the pockets And taking out two pistons in the trunk lining, we bend it back and unscrew the plastic lamb. It may not go by hand, and then it is not a sin to use pliers. At the five-door we also remove the reflector, and at the three-door we overcome the grip of the additional retainer, pulling the lantern out of the seat.
Maintenance of this machine is below average pleasure and is the fruit of the current general trend towards complicating operations that should be extremely simple. A guess is involuntarily born; and if it is intended - so that dealers will not be left without work?

We have a Citroen C4 undergoing scheduled repair, with a 1.6 (150 hp) engine, on which it is necessary to replace the drive (ribbed) belt of auxiliary units. We will show you a visual photo and video instruction, after watching which you can do everything with your own hands.

The drive belt must be replaced every 60 thousand km, or if transverse cracks appear on it. First, we move the intermediate roller away from the crankshaft pulley, it also press the belt against the pulley of the cooling system pump. We pull with our hands such a lock (latch):

At the end, its lock will work. We loosen the belt tension, for this we take the head by 30, preferably with a long knob and turn it clockwise (when viewed from the side of the crankshaft pulley):

And we push out the pin, it is spring-loaded, fixes the tensioner bar in the extreme upper position:

Our belt is loosened and you can remove it. We put on a new belt and see that it fits clearly on the pulleys. Then we loosen the tensioner on the upper roller, for this, again, turn the head by 30 clockwise until the latch clicks. When you hear it, the belt is taut. It remains to pull one roller, which we first loosened, it drives the pulley of the cooling system pump. We remove it from the retainer and sink the top cap into the body:

One of the specializations of our stations is the high-quality repair of Citroen C4. In our car services there is a specialized tool for repairing Citroen C4. Consumables, oils and fluids are available for routine maintenance. Within a couple of hours, from the main warehouse, we will bring any spare parts for repairing Citroen C4.

Before starting repairs to Citroen C4 we will make free diagnostics suspension, engine or electrics (free diagnostics in case of repair at our service stations). We do not recommend doing DIY Citroen C4 repairs. Everyone must do their job. You need to entrust the repair of your car to those who do it every day.

Citroen C4 repair cost:

It is recommended to carry out routine maintenance and maintenance of Citroen C4 every 7-10 thousand km. mileage. This necessarily includes changing the engine oil, oil filter, air filter and cabin filter. When carrying out scheduled work, we will make free diagnostics of all vehicle components and draw up a list of recommendations.

Every 60 thousand km. mileage, we recommend changing the timing belt with rollers, and if the motor is chain, then it is better to replace the chain every 120 thousand km. It is better to replace the candles every 40 thousand kilometers on gasoline engines and 100 thousand kilometers. mileage on a diesel engine. On Citroen C4 models with adaptive throttle valve, it is recommended to clean and adapt the throttle valve every 60 thousand km.

The most famous problems and malfunctions of the Citroen C4:
- acidification of the caliper pistons with subsequent uneven wear of pads and discs;
- unsuccessful design of the fuel filter - the car jerks, stalls, troit;
- creak in the car interior due to low-quality plastic - gluing with anti-creak material;
- a problem with the box - early failure of bearings and primary shaft oil seals;
- in standard cooling radiators, leak at the junction with the side part;
- a tight steering wheel - a problem with the power steering of the car - a bulkhead or replacement, according to the result of diagnostics.

The degree of wear of the Citroen C4 wheel bearing can only be determined through diagnostics.

Warranty for all repair work Citroen C4 - 6 months.

Tuning Citroen C4, like the modernization of other models of this famous French company, always begins with the refinement of the chassis. This is due to the fact that the suspension structure contains elements that wear out very quickly. Let's look at the principles of refinement of the chassis and other elements of the Citroen C4 sedan and coupe in more detail.

Quite often, from owners of coupes and sedans of the C4 Picasso model, one can hear complaints about disgusting handling. Oddly enough, this problem manifests itself already a year after buying a new car. What is the reason for such a malfunction, because Citroen has always been considered a manufacturer of passenger cars with a fairly reliable chassis. First of all, the problem lies in the low-quality A-pillars. But, even in spite of the poor quality of the racks, the manufacturer still manages to give them a two-year warranty.

Tuning the suspension of a French car can be done in two ways. The first method is a complete replacement of the racks. It is more popular with car owners who do not want to waste their time. The second option is to install spacers on each of the front wheel struts, which is much cheaper than buying new items. With the replacement of the struts, everything, in principle, is clear - it is necessary to remove the wheels, dismantle the shock absorbers and replace the standard struts with new elements. And how to perform the second option - let's find out together.

Before work, you need to purchase spacers. You need to choose parts depending on the configuration of the Citroen. If you have a Picasso model, then for its tuning you need to look for three-point parts from a domestic manufacturer TechnoMaster... If you have a larger model in the Grand C4 Picasso configuration, then look for polyurethane two-point spacers from the same manufacturer to refine it. In case you have to work on the suspension of the C4 New model, then look for steel three-point struts from a Russian company for improvement. Autoproduct.

After purchasing the spare parts, you can start working. First you need to raise the front axle undercarriage and remove the wheels. Next, using a wrench # 13, unscrew the nuts holding the supports, and install spacers in them. Then it is necessary to adjust the distance between the support plates. This is done using a clutch - we squeeze the pedal until it clicks, after which you can put the wheels. In no case ignore the need to adjust the distance between the support plates, otherwise there will be a risk of misalignment of the camber angles.

What do we get as a result of the work done? First, both the sedan and the C4 Coupe will be much more accurate in cornering. Secondly, the car will better keep on a straight track.

Chip tuning Citroen C4 is another great method to make your car better. By replacing the standard firmware in the ECU, we will achieve a significant increase in power, dynamics and torque. In addition, dips at idle speed and during gear changes will completely disappear.

To replace the standard software, we need a new program. You can download it from any free resource on the Internet. However, not all of the utilities provided in the consolidated access are suitable for a specific model from Citroen. For example, for the Grand C4 Picasso, programs from Boschreleased no earlier than 2013. Other configurations of the C4 lineup can be easily flashed with utilities from Paulus 2012–2016 and popular among our car enthusiasts software January 7.2released not earlier than 2014.In addition to the program, for independent chip tuning, we need to prepare:

The first step is to find the car engine control unit. In the sedan, the ECU is located directly under the steering wheel of the car, while in the C4 Coupe, the block slot is slightly offset to the left. Remove the protective panel and connect the adapter to the K-Line block using a USB adapter. We connect the other end of the adapter to the laptop. Next, we start the car to check the connection. If everything is in order, then disconnect the adapter from the laptop for a while and proceed to installing the programs. First, we install the PAK Bootloader driver, and then copy the new firmware to the hard drive.

We reconnect the adapter to the laptop. Also, in parallel with the K-Line adapter, you will need to connect the PAK Bootloader to the computer and the car ECU. We are waiting for the folder with the data on the auto block to appear on the computer display. Open this folder and look for a file with the extension .bin in it. Next, we open the archive of our new firmware, choosing the final folder for its installation, in which the file we found is located. The display will show a warning about data replacement. Press the "Ok" button and wait for the PAC Combiloader Loader to work.

Its main purpose is to help us correctly configure the available machine systems. So, you can calibrate the parameters of the engine and transmission, increasing the power and improving the car's response to the gearbox.

It will also not be superfluous to customize the fuel and exhaust systems. In doing so, adhere to this principle: when moving the slider of the fuel system to the right, set the slider to the same position. After configuring the systems of the machine, click “OK” again and wait until the installation of the firmware is completed. Do not be afraid if the engine stalls several times and starts on its own - this is normal when replacing the unit software. At the end of the installation, we disconnect the adapter and the PAK Loader and test the car. You will notice changes in the operation of the machine from the very first revolutions of the engine. The sound will be completely different, the motor will run more stable and smoother.

After the chip tuning, your sedan gets about 20% more power and 15% more torque. If you have a C4 in the Coupe configuration, then these figures will increase by 25 and 22%, respectively, due to the lower weight of the car. Fuel consumption will decrease by 0.7–0.9 l / 100 km. Plus, you won't have to worry about idling dips.
