Hi guys. I have S3 8l 2001 AMK .. There is a problem which I cant handle with .. The car is still stock , and I have a boost loss , what I mean is that ..
When I start to accelerate hard it has no problems , the boost gauge shows like 0.7 bar's of boost , but when I took my foot of the throttle the problem kicks in and its like no boost , I mean the gauge shows 0.3 bar's of boost maximum ..
When I turn the car OFF , then ON , there is no problem till the next time with the hard acc. The DV is Bailey DV26 dualpiston , have no boost leaks between components , seems like I have no vacuum leak too ..
I have tried with another MAF from S3 8l AMK , the MAP seems to be OK , N249 bypassed , although I have tried with another DV Forge .. Do you have any suggestions ??
Thats the code what VCDS give - Pressure drop between turbo and TB ( I have cleaned the TB - needed no adaptation !!! ) When we clean the code on a running car , it seems to be okay , but then the code appears again ... What shall I do ??? Sorry for my bad English , greetings from Bulgaria ))
