Engine electronics malfunction

[Killabee]

Yesterday, a light in my ****pit appeared. I looked it op, it meant a malfunction in the engine electronics. So today I went to audi, and on my way there the light went off.

I do have problems with the car sometimes, like when I give full throttle it sometimes doesnt go on but hassetates, I had a couple of times the engine shut off, and last week the rev meter went offline for a second.

After the dealer checked the car, they said they couldn't find anything. Which disappoints me because I know there is something.

Does anyone know what my problem is or did someone encounter the same problems?

Sounds like an lambda (air-flow) sensor to me. But suprised to hear that Audi could not read any errors off the ECU.
Have a go at finding any fault codes yourself maybe:

revmeter goes off, engine stops, but you don't have to turn the key for it to restart?
"drehzahlgeber" - "rev-sensor" is your problem. had it, got it sorted, no issues. go to the dealer and explain - it is a known fault.
there's generally nothing saved in the faultlogs and no orange light.
