    Hello,
    at the outset, I would like to point out that I looked through all the topics related to my problem and found no solution. The car behaves typically to the situations described by others, namely it fires without a problem (from the kick) after some time the orange service lights pop up and the "spiral" car loses power, as if the turbine was cut off, after a while the car warms up usually after exceeding 2000-2200 rpm / min cuts it off, the red stop engine light pops up. (no STOP sign) The car goes out, just turn the key in the ignition switch again and the car fires without any problem. After a while, the whole procedure repeats itself. Error DF053 pops up, rail pressure regulation function, 3 DEF Increasing the amount of exhaust gas recirculation. Now, about what has been done, the car was visited early by the "quack" who fought the problem of starting the car. Lots of sensors are replaced with new / original BOSCH. Crankshaft sensor, camshafts, pressure regulator on the pump, pressure regulator on the ramp, both electronic and mechanical, and a new Lambda probe (5-wire) was also purchased. The sensors are new original. I picked up the car today from the RENAULT service. They concluded that the injectors and high pressure fuel lines should be replaced. Overall, I got the impression that they want to get rid of this car and the problem. I don't think it was the fault of the injectors and when they asked them if the car would drive then they answered evasively. I can buy these injectors, etc., only if the car starts to drive, because no one gives a guarantee, and it is not a trick to buy and throw money down the drain, which unfortunately has already happened before, because these sensors cost a few pennies. The injection pump is checked approx.
    Maybe someone from Lodz or the surrounding area could help me with this car, because even the website ignored the topic. The car has been standing for 4 months, generating costs and no one can determine the fault.
    I'm begging for help.

    Do you have the EDC15 or EDC16 driver there? If you enter the BOSCH number, I will check the driver. In EDC16 there is a preliminary fuel pump in the tank, knowing the life, no one looked at it.
    By the way, did you pay something on the site for their "diagnosis"?

    I do not have the opportunity to view the number of the controller at the moment, but I have photos from CLIP with the error marking and description and on the top it says "electronic module EDC16 C36 injection"
    No one ever mentioned some primer pump in the tank ...
    When it comes to the service, yes, I paid for the diagnosis, computer checks for errors (PLN 150), fuel system test (PLN 600) at the promotional price, I paid "only" PLN 550 ... and the car drives like this ...

    then if you find a fault, it's just a matter of going there ... although in total, what a poor service advisor has to do with it ...
    It is worth checking if the relay has the correct deflection, if it is not burnt, if the pump connector is not burned and if the pump is working properly ;)

    Unfortunately, this model does not have any additional pump in the tank ... Could these errors be caused by some mechanical damage? E.g. head (levers, shafts, maybe the valves do not open fully)

    Mi ESItronic says there is a primer in this car with an EDC16 type system. EDC15 does not exist. weird

    The low pressure fuel pump is on the right side of the bottom, you can say at the passenger level, often the ends on the connectors oxidize and the pump does not provide enough fuel

    In such cases, the return test on the injectors and on the injection rail after the safety overflow valve. What are the values of these transfers?
    Maybe the RENAULT service is right (maybe they did the overflow test) and it turned out that the injector overflows are outside the norm, and the injection pipes are replaced after each disassembly with new ones.
    You paid for the fuel system test on the site, request the results of this test.

    In the receipt note, they wrote:
    "CLIP diagnostics - defect of the rail adjustment function, fuel supply system control - injection pump at start-up 230bar (minimum value 170bar) test of injectors 3 and 4 injector from the flywheel side, recommended replacement of 4 injectors + high pressure injectors lines, leaky injector overflows."

    From the telephone conversation, the injections reportedly had 1 and 2 30ml each and 3 and 4 50ml injections. (injection No. 1 was regenerated 2 months ago, cost almost PLN 850)

    It is strange that the car has no problems with starting. When asked if it would be ok after replacing the injectors, they could not directly answer that.

    Yesterday I dismantled the top, because there was a large oil leak from under the valve cover, I will have the injectors checked, you will know then 100%.
    I am puzzled by the fact that the rollers are terribly "worn" on the bushings and the levers also look "broken". Looks like the valves didn't open as they should.
    Is it possible that the car is not getting enough air? EGR is not able to take more air than it needs for the appropriate mixture and thus, for example, cuts its fuel? (EGR is blinded.)
    Thanks in advance for the hint.

    You would buy a new one for that.

    Why? How did you blind the EGR, you turned off the control "programmatically"?
    Here you have a problem with the word Service and the spring.

    The error context tells you where the problem is.

    The EGR has been blinded at the head with a piece of "badge" for several years (mechanical damage to the engine inside it), the "spring" and SERV were on, but it had no effect on driving the car. At the moment, the EGR and throttle are replaced as the tooth of time has eaten the pins. Everything is as it should now, so I will probably unblock this egr. After turning the ignition switch, all the controls light up and after firing everything goes out as it should be. Only after exceeding 2200/2400 revolutions, the whole procedure described in the first post begins.

    After letting go of the gas, or during acceleration too?

    Only when accelerating the car. If I start the car and drive to 2000 rpm nothing happens. As he accelerates, he cuts it off by lighting the STOP ENGINE. The car goes out, I turn the ignition switch and it fires without any problem and you can do it over and over again ...

    Importantly, this only happens when the car warms up a bit, it does not cut it off in the cold.

    Overflows on injectors 1 and 2 are normal. It was exceeded on 3rd and 4th, but slightly.
    There is a problem with a loss of fuel pressure or too little power supply to the system.
    He gets little fuel.
    There may still be a problem in the tank (clogged / leaky dragon) Problem with flexible fuel lines (broken / inserted reducers / connected webasto), Problem with the vent bulb. The problem with the fuel filter housing - clogged fuel channels. The problem with the injection pump - worn out. Problem with the overflow valve of the ramp - it opens at a higher pressure than the one during the manufacturer's tests and did not come out in the service, and it may go out while driving.

    I gave the car to an electrician to check the entire installation. It turned out that everything is ok. Something showed as if there was a short circuit in the controller. We bought a new computer and an electrician transferred and reprogrammed everything into it. The final part is that the car is still standing by an electrician to this day. Yes, over a year !!! He was so eager to repair that at the moment the car does not start and it is not possible to check whether the fault has been removed. The amount of time that is standing caused the destruction of other components, such as the injection pump, pressure sensors, etc. It looks like the final of this repair will be in court ...

    Thanks for the answer Good luck in court

Topic summary

The discussion revolves around a Renault Master 2.5 DCI experiencing power loss and error DF053, indicating issues with rail pressure regulation and exhaust gas recirculation. The vehicle starts without problems but loses power after reaching 2000-2200 RPM, triggering the orange service light and the red stop engine light. Various components, including sensors and injectors, have been replaced, but the issue persists. Participants suggest checking the low-pressure fuel pump, injector overflow values, and potential mechanical damage. The author has also mentioned that the EGR was previously blinded and is considering unblocking it. The conversation highlights the complexity of diagnosing fuel system issues and the potential for further mechanical problems.
