Audi A5 2.0 cr tdi, Non start, No Codes

[jim potter]

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

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

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.

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?

[jim potter]

Shall be checking this tonight now i have some.
also looking to check for blocked filter or failed pump after i have given it some squirt to see if it fires.

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.
