I have had misfire on cylinder 6 & 8 and now 8 is gone after replacing both turbos, both injection valves to the cylinders , all spark plugs. Also checking compression test on all cylinders and testing the coils with good results.
cylinder 6 misfire is still there and the engine runs very bad. I have changed oil, oil filter and air filter, also poured in 20l of good fuel.
What could I do more?

What does the diagnostic scan show? just the cylinder misfire? Swapped coilpacks from good one to no 6? Have you checked wiring with a load test?

Yes only misfire on 6. What is a wiring with load test?
Audi checked all the coils with a “ociliscope” or something called like that and they were okay.

Interesting, if you were at Audi and they can’t solve a problem
