Hello, I’m new here and I would like to introduce myself briefly, my name is Christoph is 21 years old and from Austria.. I bought a Volvo 850 T5 last year was quite happy with the vehicle until after about 8000km one of the Pleullager failed, well then I put the engine and the turbo again and sealed off.. At the beginning everything was good and after about 3000km I wanted to try the turbo and quickly noticed that he did not build a charging pressure, then made the py-pass membrane new and washed out all the underpressure lines and the charging pressure control valve with cold reamer, the first 100km was all perfekt until then short from 4500 rpm a whistle was heard and the engine stuttered, ignition shut out immediately from the there is all new up to ignition cable and ignition module, error code was also negative. My thought out are the charging pressure hoses could cause the problem..
