Does anyone have any other idea which of the 1,000,000 electronic parts could still be the cause??
I think I'll start over first.
Had/have a wave-like acceleration, had the error memory read out, which has saved an error and can not be deleted "00515 003 Hallgeber G40 no signal"
Air mass meters have been tested and are ok.
The fault only occurs when the car is cold and the Lambda connected. So Lambda!! I built a new Audi Lambda today, and I've got wave-like acceleration again, and on top of that, I've run out of it at the traffic lights when I started.

Lambda off and he runs 100%, that can't be!

And if that's not enough after I really warmed him up for 1 hour freeway, he smokes at the front left somewhere from the moto room, I have no idea what smokes there, it's all dry, no oil, no water!!

I wanted to go on holiday next week, but like the V8 at the moment I don't trust myself with it the 1,800 km!!!
Welcome

Stecker geprüft ob die richtig angeschlossen sind, waren sie "LEIDER". Also Lambda wieder abklemmen und ohne fahren bis der Fehler gefunden ist.
