I need ECU wiring diagram for Audi A3 2.0tdi, engine code BMN, typ 8P year 2008, the car wont start because fuel pump doesnt work.
Check F 27 is ok, if i make jump fuel pump work but car doesnt start, i think fuel pump relay is okk maybe fault some signal from ecu to relay.

DTCs present: P1541 - fuel pump relay(J17) OPEN CIRCUIT
P0684 - glow plug control module(J179) IMPLAUSIBLE SIGNAL

If someone can provide me ECU wiring diagram ill appreciate

Cheers

Check your injectors you must have one of the injector shorting to ground that's why the ECU has closed the fuel system so your engine don't get more damage..................

Disconnect one injector at a time and see if it starts as some time if you are unlucky you might have more then one injectors faulty.......So its nice if you have multimeter check resistance between injectors pins and to ground..............

Hi m8s

With support from ELSA, from my friend's laptop, i noticed that black and yellow wire was without power protected by a 5A fuse "F15" from the engine box compartment, but the fuel pump relay did not work as due.
After having them ready the car started normally.
Thank you for your cooperation Ashraf6119
