Audi S8 FL 6-speed vibration at idle

Hello, colleagues!

I've been reporting on my problem a while ago.

It shakes my S8 6-speed FL easily in idle mode. It is only very easy to feel but clearly. You can also see it by vibrating the gear lever.

The tachometer commutes in the almost invisible area, so actually normal. He's also full of performance and really pulls well. I tried a couple of KMs the other day against a 340 hp S6 and I noticed a little bit more performance towards him.

The following has been done so far:

-Air mass meters NEW
-8 x rod ignition coils NEW
-Rossel flap cleaned & re-learned
- camshaft adjuster controlled
-All errors read out incl. Diagnosis of the actuator

Well, engine engineering, we're finished with our Latin... what else could be exchanged or exchanged? Test?


Now the guess remains engine bearing:

It is and remains the error "magnet valve engine bearing right, short circuit after mass". The right motor bearing does not "click" in the actuator diagnosis either. On the left the "click" is clearly audible!

Was wir hier bisher probiert haben:

New engine bearing purchased for testing, not installed but plugged in. Mistakes BLIEB present! We deleted it and it was back immediately, although a factory new warehouse was hanging on the cable! So camp returned and made the following:

We have then measured whether something arrives at the line to the engine bearing, since with the measuring instrument also signals are detected. So the line is definitely not dead!

Now we have put the engine bearing on permanent plus and then on permanent minus. It would have to be "soft" in some state and not transmit the vibrations, would it?

It definitely didn't do anything, the vibrations are still there and easy to feel...

It kind of bothers me, you don't notice it when you drive, but you can feel it clearly in the stand.

Maybe someone else has a tip for me!

Thank you and have a nice Sunday from Austria!
