Hello, my 80s is actually not really great since I did it, but I always thought it might not be better. But now I drove the one from a colleague (even unchiped) and must say that this one is better about worlds. So I did some troubleshooting. First I wanted to read out the engine control unit which did not work for inexplicable reasons, with the ABS control unit worked. Then I measured the charging pressure once. The result was mic h very surprised, when accelerating from approx. 2000 rpm the charging pressure goes short to 0.8 bar and then sinks immediately to 0.5 bar. If I accelerate from 1500 rpm then it does not rise at all higher than 0.5 bar. I then checked the Turbo, the AGR valve and the Wastegate and all this works perfectly. Then I put the hose off the Wastegate and thus the charging pressure also increased to 1 bar, but without which the performance has improved noticeably. he who wants, in my opinion the power would have to increase by a lot if the charging pressure rises from 0.5 to 1 bar. Or is there perhaps something else in the bucket? The engine control lamp burns in any case not therefore I do not think that it goes because of a defective charging pressure generator in emergency run. I hope one can help me here.
