Do-it-yourself Citroen c4 sedan repair

The Citroen C4 car first saw the light in 2004, and 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 features. The latest versions of the car are thoroughly “stuffed” with various electronics, which sometimes helps out, but sometimes ruffles the nerves, and then the repair of the Citroen C4 becomes necessary. But first things first.

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

• Classique
• Confort
• Exclusive - a variation for a hatchback
• VTR, VTR+ and VTR Pack - coupe variation

As for the correct choice of model - this is a personal matter for everyone. Repair of the Citroen C4 Picasso through the time of operation may be needed in the same way as the Citroen C4 Cactus. Therefore, the essence is not so much in the principled choice of model and configuration, but in the knowledge of the weak points of the machine, which, in turn, sometimes need to 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 the city 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, Citroen C4 repair is very often associated with automatic transmission malfunctions. Sometimes the valve stops holding, sometimes the entire valve body fails, and it also happens that the band brake completely breaks, as a result, the box simply wedges. No matter how manufacturers fight over this problem, they cannot fully solve it. Therefore, often lovers of the C4 model wisely choose "mechanics".

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

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

And so the car, of course beautiful, the designers did their best. But you won’t be full of beauty alone, so do not forget to carry out timely maintenance of the Citroen C4, and periodically look at nodes that are prone to weaknesses.

It was like this .... I drove another 20 tyrov, I think it's time to do MOT, the warranty ended a week ago, up to OD-1500 km, in short I ordered through> consumables, the day was warm today -5 in total and I set to work on the street near the house. I've had experience with replacements. Previously, he already held a Frenchman and had to change filters. Russian roads, no matter what they say, they are 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, that's for this Shumkov.

there is a hole like this:

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

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

Now the air filter, it’s certainly more difficult here, at first I was tired of how to unscrew the far screw

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

We also unscrew the brake fluid reservoir, now access has become better, unscrew the bolt holding the filter housing:

disconnect the air vent by pressing the "yellow":

nothing else holds it, carefully take it out and open it without worrying, I brought it home, cleaned it of sand, inserted a new filter.

Now the candles, remove the lining from the engine (6 screws), disconnect the air ducts by pressing the "yellow" 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 to the conscience!)

Candles, in principle, are working (36,000 passed) - they have a coffee color (leave it, it will suddenly come in handy!)

And now everything is in reverse order, slowly, with feeling, really with the arrangement!

I still have front brake pads (I also think I will replace it myself), I decided to try “TEXTAR”, because relatives creak terribly, I took these at random, but I hope for the best, the company seems to be normal and there are also rubber bands on the brushes (not native, but they fit), 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 (2008 prices):

oil, I went to replace it at the station, it was reluctant to remove the armor, they sucked it for 200 r, to unscrew the oil filter you need a head on “27”, now everything seems to be ... Perhaps someone will come in handy!

TOTAL DEPENDENCE (Oil change)!

We change the air filter: having released the latch, we pull up the plastic resonator of the air duct, simultaneously removing the corrugation from it. We unscrew the filter housing bolt and loosen the pipe clamp on the throttle assembly. Now we remove the brake reservoir, unscrewed a couple of screws under - Torx-20, and take it aside.

Shaking the body up and down, we shift the pipe from the throttle assembly and take out the body. We turn out the screws around the perimeter and, having removed the cover, change the element. When assembling, make sure that the pipe fits snugly on the throttle assembly!

To replace the spark plugs, unscrew the six self-tapping screws of the engine trim and four bolts of the ignition modules. We remove the crankcase ventilation hoses by pressing the yellow tip retainers. Having lifted 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 connector was not disconnected). Candles - turnkey for 16 ".

There is an automatic in the drive of Attached units, which is great - you can't go wrong with the belt tension force!
For a timing belt, about the same device, but semi-automatic. To set it to working condition, you need to combine the arrow on the movable sector with the front sight on the stationary one. If you have had to change a belt with a similar drive pattern, there will be no difficulties. Another thing, according to the French tradition, there is not a key or a pin in the pulley-crankshaft connection. That is, by unscrewing the central bolt, you can endlessly select the correct position of the shaft with the pulley. Here you can not do without mandrels! There is nothing special about 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 rod. 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 before 2006), the pistons have to be turned in different directions, which means that two devices are required - with a right-hand thread and a left-hand 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 of wear products and lubricate. And change the guide bolts - they, with locking sealant on the threads, are supplied in the original kit.

Changing the bulbs in the headlights, at first glance, is not difficult. It seems that access is normal, and it is easy to remove the rubber plugs of the case. This is confusing: when some kind of headlight bulb burns out, the owner takes over. It wasn't there! The block sits so tightly that the effort of the fingers is simply not enough, and sticking the brush in order to grab it tighter doesn’t work - it’s not enough. So I want to pull off the connector with pliers. Do not rush - you can easily pull out the landing clip on the reflector with the root. It is better to make the simplest device: we bend a strip of steel 1.5x10x150 mm and form 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 along 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 foglights, the same trouble as on many other cars: there is a lot of dirt in the work area. In addition, here it is necessary to remove the bumper skirt - unscrew seven bolts under the "Torx-20", three turnkey "by 10" and also squeeze out a couple of latches. It is extremely inconvenient to work without a lift.
We remove the lanterns to replace the lamps - sadly, this is the modern trend. Having removed the pockets And taking out two pistons in the trunk lining, bend it 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 lock, pulling the lantern out of the seat.
The maintenance of this machine is below average pleasure, it is the result of the current general tendency to complicate those operations that should be extremely simple. Involuntarily a guess is born; and if so, so that dealers do not remain without work?

We have a Citroen C4 car (Citroen C4), with a 1.6 engine (150 hp), on which it is necessary to replace the drive (river) belt of auxiliary units, for a scheduled repair. We will show you a visual photo and video instruction, after viewing which you can do everything yourself.

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

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

And we put forward the pin, it is spring-loaded, fixes the tensioner bar in the uppermost position:

The belt is loose and can be removed. We put a new belt and see that it clearly stands on the pulleys. Then we loosen the tensioner on the upper roller, for this, again, turn the head 30 clockwise until the lock clicks. When you hear it, then the belt is tensioned. It remains to tighten one roller, which we first weakened, it sets in motion the pulley of the cooling system pump. We remove it from the latch and sink the top cap into the case:

One of the specializations of our stations is the quality repair of the Citroen C4. In our car services there is a specialized tool for repairing Citroen C4. In the presence of consumables, oils and fluids necessary for scheduled maintenance. Within a couple of hours, from the main warehouse we will bring any spare parts for the repair of Citroen C4.

Before starting the repair of the 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 do-it-yourself 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:

Routine maintenance and maintenance of the Citroen C4 is recommended to be carried out every 7-10 thousand km. run. This includes changing the engine oil, oil filter, air filter and cabin filter. When carrying out planned work, we will make a free diagnosis of all components of the car and make 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 change candles every 40 thousand kilometers on gasoline engines and 100 thousand kilometers. mileage on a diesel engine. On Citroen C4 models with adaptive throttle, it is recommended to clean and adapt the throttle every 60 thousand km.

The most famous problems and malfunctions of the Citroen C4:
– acidification of caliper pistons with subsequent uneven wear of pads and discs;
- unsuccessful design of the fuel filter - the car twitches, stalls, troit;
- creaking in the car interior associated with low-quality plastic - sizing with anti-creaking material;
- a problem with the box - an early failure of the bearings and seals of the input shaft;
- in standard cooling radiators, leak at the junction with the side part;
- a tight steering wheel - a problem with the car's power steering - a bulkhead or replacement, according to the diagnostic result.

The degree of wear of the Citroen C4 hub bearing can only be determined during diagnostics.

Warranty on all repair work Citroen C4 - 6 months.

Tuning Citroen C4, as well as 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 design contains elements that wear out very quickly. Let's look at the principles of finalizing the chassis and other elements of the Citroen C4 sedan and coupe in more detail.

Quite often, owners of coupes and sedans of the C4 Picasso model can hear complaints about disgusting handling. Oddly enough, this problem manifests itself 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 poor-quality front struts.But, even despite the poor quality of the racks, the manufacturer still manages to give them a two-year warranty.

There are two ways to tune the suspension of a French car. The first way is to completely replace the racks. It is more popular among 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 elements. With the replacement of struts, everything, in principle, is clear - you need 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 tuning it 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 struts from the same manufacturer to refine it. If you have to work on the suspension of the C4 New model, then look for steel three-point struts from a Russian company to improve auto product.

After purchasing parts, you can start work. First you need to raise the front suspension axle and remove the wheels. Next, with the key No. 13, we unscrew the nuts holding the supports, and install spacers in them. Then you need to adjust the distance between the support plates. This is done with the help of a clutch - we squeeze the pedal until it clicks, after which you can put the wheels. Never ignore the need to adjust the distance between the base plates, otherwise there will be a risk of misalignment of the camber angles.

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

Chip tuning Citroen C4 is another great way to make a car better. By replacing the stock firmware in the ECU, we will achieve a significant increase in power, increase in dynamics and torque. In addition, dips at idle 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 particular model from Citroen. For example, for Grand C4 Picasso, programs from Boschreleased before 2013. Other configurations of the C4 range can be easily flashed with utilities from Paulus 2012–2016 and popular software among our motorists January 7.2, released no earlier than 2014. In addition to the program, for independent chip tuning, we need to prepare:

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

Reconnect the adapter to the laptop. Also, in parallel with the K-Line adapter, you will need to connect the PAK Loader to the computer and the car ECU. We are waiting for the folder with data on the auto block to appear on the computer display. Open this folder and look for a file with the .bin extension in it. Next, 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. We press the “OK” button and wait for the Combiloader PACK to work.

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

It will not be superfluous to also adjust the fuel and exhaust systems. At the same time, adhere to this principle: when the fuel system slider is moved to the right, set the exhaust slider to the same position. After setting up the machine systems, click “OK” again and wait for the firmware to be installed. Do not be afraid if the engine stalls several times and starts up on its own - this is normal when replacing the block software. At the end of the installation, turn off the adapter and PAK Loader and test the car. You will notice changes in the operation of the machine from the first engine revolutions. The sound will be completely different, the motor will run more stably and smoothly.

After the chiptuning, your sedan gets an increase in power by about 20% and an increase in torque by 15%. 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. In addition, now you will not worry about failures at idle.
