Hi, there, first of all I would like to ask if somebody has a wiring diagram for both (AAT and AEL) ECUs'?

I own Audi 100 2.5 TDi (AAT), and few days ago I bought fuel pump, ECU, Immo + keys + reader and the gas pedal from a Audi A6 2.5 TDi (AEL).

All the components are attached, and now the engine is running, but it's undriveable, when I step on the gas pedal the car jumps.

VAG-COM is giving me those fault codes:

00542 - Needle lift sensor (G80)
05-00 - Input Open
00777 - Accelerator Position Sensor (G79)
27-00 Implausible Signal
01054 - Power supply Relay: Terminal 30 (J317)
27-00 Implausible Signal
01117 - Generator Terminal DF Load Signal
27-00 Implausible Signal

The CHECK ENGINE lamp is blinking, but I'm guessing it's because of the first fault code (00542).

I would appreciate any ideas or advices at all. I thing I must rearrange the wires, but I can't find wiring diagrams of both (AEL and AAT) ecu. I've got one from Autodata 3.18 for the AEL engine, but there is nothing there for the AAT, so I don't know how exactly to arrange the wires.

P.S. The gas pedal on my Audi 100 has different jack of the A6 one, and it has 4 wires compare to 5 for the A6. The engine was revving by itself, but after I connected PIN6 from the jack to a ground, the car started working normally, well the idle rpms are a little bit higher (around 1050rpm, that is what Vag-Com says).

Thanks in advance!

You will probably have better luck elsewhere; we didn't get the Diesel engines in the USA, and this site is primarily US-based.
