Hi all, asked about this car in another part of the forum but thought id post the results in the correct forum.

Its a A3 2.0 TDi SE , BKD engine, 140 BHP 2004 with 108,000 on clock, full history 2 owner car

Problems it has, it wont idle properly (jumping about all over the place, but only when the engine is up to temperature, doesnt do it when cold) and secondly it wont cruise between 2000 and 2500 revs it starts spluttering and lurching.

Did some logs and the results below, only ones that look off are to do with the injectors, mainly the deviation

It's either injectors or injector wiring harness. Turn car on and run live log of injectors to see what the quantities are ...
