    Hello, I have a problem with the car consisting of a problem with the electrical installation going to the throttle. For some time, the car went crazy, fired, drove normally, something went off while driving, the STOP was on. Sometimes it fired, and sometimes you had to wait a few minutes for it to fire. The computer showed strange errors in the sensor of the camshafts, crankshaft. I bought a new one, nothing helped. Wkońcu stopped firing at all, then the computer showed damage to the throttle and EGR. After disassembly, it turned out that the pins in the components and the ankles are practically non-existent, time consumed them. I bought a new EGR and Dampers. After adapting the computer, the car started to drive and start. Unfortunately, it took 3 days. Now there is the same problem again, the car went out while driving. It only fired after a few minutes. Now I don't want to smoke again. Computer shows damage to the throttle harness. The question is if someone has had such a case. I bet that the fault lies with the electric wires, whether they are bent somewhere and just one current flow, and not one time. Without a pattern, it's hard to get to the bottom of the matter. The last masterek causes a lot of problems, a lot of parts replaced with new ones, alternator, starter, power steering pump, injection, battery, now throttle, EGR, most of the plugs were soldered (already cleaned). I don't know what to do next. Is it possible that the computer has been damaged? The problem is also the turbo that works once and does not. Here is the simplest turbine, which is only relieved by a valve, there are no electrical elements in it. Help me please, because I do not know what to replace / repair next, so that the car starts to run normally. Thank you in advance and best regards.

    Unfortunately, the French created a piggy bank, not a car, this applies not only to your model but also to Laguna Master and Clio, it is about DCI engines, no matter what capacity, the tow truck queens, their problems are already described on the forum. Turbine underpressure, remove the plastic pipe from the Turbine that supplies air to the manifold, check the Turbine for tightness and axial clearance. As for the throttle, check the voltage on the throttle plug, because the cable is damaged or the relay.

    Try to hand over the car to someone who knows about Renówki. Good diagnostics and control of the installation. For someone who works with pensioners, it takes 1 day of work and you have your car working again.

    Admit the mileage of your car, I'm afraid if it's a tarpaulin, it's about 1 million kilometers, and if it's a tin, it's probably 400,000 km.

    Unfortunately, home mechanics are not adults to operate these vehicles. Their failure rate is largely due to improper operation (cleanliness, standards of operating fluids, Chinese replacements of parts because the originals are too expensive, etc. ...). Of course, there are years that were more failures than their competitors at that time, but it was over 10 years ago and every company has such mishaps to their credit.

    Personally, I would get rid of Renault in your place, the failure rate will make your wallet empty and the car will not run normally

    And what would you recommend Peugeot / Fiat, VW or maybe Mercedes to him? He needs a decent professional.

    In the attachment there is an injection diagram for your master if it helps you in something.
    1461 is a throttle
    120 is an injection controller

    The car has traveled 650,000 km.
    The engine overhaul was done around 100,000 years ago. Bought whole bottom (original) new factory original head and many many other parts. I don't buy "Chinese". I prefer to pay more and have a better product and therefore less breakdown. I bought the car when it was 2.5 years old and the mileage was 350 thousand. Everything is changed on time, oil, fluids etc. etc. I understand that I don't care for the car, but it is really kept on a level. So far, despite the fact that it is a rennovation, I can not complain, because the car was really failure-free until now. Today again, when playing with CLIP, an error in the pressure sensor on the rail (DF537), throttle error (DF226, intake valve circuit) pops up. Oddly enough, the car caught fire. Repeatedly. However, it looks as if the throttle does not work at all. The computer shows 96% throttle and this value does not change. The strange thing is that only the middle plugs are dusty. Two exterior are impeccable. Strange things happen, sometimes mistakes are, sometimes they are not, sometimes they are permanent, sometimes they can be deleted. Once the car fires and not. Because the turbine issue, I understand that it may be related to a non-working throttle. Perhaps someone knows a specialist in £ód¼, who would locate this fault? Send for service? Only if then my heart can stand when they issue fv ...

    You don't think everything can go wrong with this run.
    After all, it is not a bus or a tractor unit counting on millions of kilometers with an engine not exceeding 2500 rpm, into which the oil barrel enters? Starter, alternator, injectors - after all, these are consumables that will break sooner or later.

    I don't understand such texts. What would be the point of producing eternal things?

    Why should it work? Are the conditions under which it is supposed to work?

    I don't really see any connection here.

    After all, ASO does not repair it, but consults every action with the owner. If you are not satisfied with the amount for a given activity, you take the car and pay only for what you have previously agreed.

    Dear colleague genek1000,
    with all due respect, but answering the questions did not help.
    Besides, the topic is finished and the car flies as before.
