    Hello everyone,
    I have problem with Audi a4 1.9 TDI 2006, engine brb. Car doesn`t start and there are no errors on the computer. I think that I checked everything - pd, distribution, compression, mass, fuel supply, booster pump, high pressure pump.
    Does enyone has the same problem?
    Thank you for your help.

    tow it to see if it starts or bump start it

    might be starter not turning car over fast enough, looking at around 280 rpm for starter to allow fuel to run

    Thanks for answer. I tried to tow the car but it doesnt want to start either. Problem with that car is that the injections dont pump fuel but i cant find the reason why this is happening.

    is the cambelt still intact ?

    do you think the camshaft sensor is ok and cambelt is aligned correctly ?

    changed the fuel filter etc ?

    think its time for a vcds scan

    Cambelt is ok and correct.
    I changed fuel filter, regulator valve on the filter, tandem pump, and pd.
    The compressing is ok.
    vcds:
    No trouble code...
    I have seen the engine speed and cam.
    all temperatures are ok.
    All the earth and plus to the engine module was checked.

    Sorry for timing. We managed to solve the problem - it was bad motor controller.
