I used a bosch lambda, nr : 0 258 003 957, same as audi nr: 034 906 265 F.
I have to do a pressure test, then i know more.
I must have 2 bar turbo pressure, i only reach 1.5 bar.
The car loses much turbo pressure at 5000 rtm, at 6000rtm he has 0.9 bar.
My car has black smoke when I accelerate, he almost switch off when i use the clutch.
And my lambda is very black.Comment

tell you what.
look for a leak but replace the lamda again.when i had a different problem and my car was running very rich,i fixed the problem but the lambda was then shot and it had only 10000Kms only.so being rich for a while tends to destroy the lambda sensor.Comment
