    HI all,

    friends Audi a5 died the other day leaving him stranded on the M25.
    symptoms were major vibrations then it just died.
    he got it recovered home and i then popped rounf to scan it.

    no codes showed, so i went to start it and it would crank but not fire.
    at this point i checked the injector variance, and noticed injector 2 was massively difference to the rest.

    See below

    Address 01: Engine (03L 906 018 JG)


    10:02:02
    IDE01387 Injector 1: rail pressure calibration point 1 0.00 s
    IDE01388 Injector 1: rail pressure calibration point 2 0.00 s
    IDE01389 Injector 1: rail pressure calibration point 3 0.45 s
    IDE01390 Injector 2: rail pressure calibration point 1 1.20 s
    IDE01391 Injector 2: rail pressure calibration point 2 -17.60 s
    IDE01392 Injector 2: rail pressure calibration point 3 -13.90 s
    IDE01393 Injector 3: rail pressure calibration point 1 2.85 s
    IDE01394 Injector 3: rail pressure calibration point 2 0.60 s
    IDE01395 Injector 3: rail pressure calibration point 3 -0.95 s
    IDE01396 Injector 4: rail pressure calibration point 1 0.00 s
    IDE01397 Injector 4: rail pressure calibration point 2 0.00 s
    IDE01398 Injector 4: rail pressure calibration point 3 0.00 s

    feeling fairly confident that injector 2 was faulty, purchased a new one and fitted it.
    coded it, went to start the car and nothing!
    again it cranks but will not start.

    Address 01: Engine (03L 906 018 JG)


    11:40:32
    IDE00475 Fuel Pressure Regulator Valve 44.59 %
    IDE00476 Fuel Metering Valve 29.14 %
    IDE00589 Fuel pressure 11950 kPa rel
    IDE01389 Injector 1: rail pressure calibration point 3 0.45 s
    IDE01392 Injector 2: rail pressure calibration point 3 0.00 s
    IDE01395 Injector 3: rail pressure calibration point 3 -0.95 s
    IDE01398 Injector 4: rail pressure calibration point 3 0.00 s


    Fuel is getting to the injectors, i have not yet checked the bowl on the HPFP (next to do).
    But wondered if anything else would stop it starting.

    i can confirm crankshaft sensor registers rpm when cranking, Fuel pressure rises.

    Anyone else had this ? as i suspect it is not unique to this car.

    Regards jim.

    Does it fire up with a sniff of brake cleaner?

    Be very sparing with the sniff and have a hand on the key to shut the V157 flap if the engines goes ballistic… serious brown trousers time.
