Hello,

Quote:

I can pretty much get into any kind of STG, young or old.
from the C4 air conditioner to...
1Z TDi, V6 TDI, 3-liter Lupo, Golf 4 FSI, 1.4 16V, etc.

Unfortunately, I'm having trouble accessing the engine control unit (ECU) of my own.
Audi 100 C4 2.8l V6 AAH, manufactured in 04/1992, does not fit.
He doesn't even do squats 1, 2, 3, 4.
but remains on baud00 and tries 1-4 (as if the ECU doesn't exist)

Has anyone experienced this before, and/or have any ideas about it?

Best regards, Rainer.

The AAH control unit likely requires a trigger signal on the L-line. Does your interface support that?

Sure, provided that the correct pin on the OBD2 connector is connected to the circuit board icon_smile.gif.
