Hello, I built another engine in winter in meien 1.8ter a4, namely a 96er 1.8T With 150hp (AEB engine) normal without tuning. Now everything went after some minor problems. Now to my problem: Sometimes, when accelerating the charging pressure stopped at approx. 0.3bar, when I am from the gas and then immediately gave gas again it is again high to approx. 0.7 bar. But since last Sunday the charging pressure does not exceed 0.2 to 0.3 bar. The acceleration is like as o b amn only drives quarter or half-gas, and I think the engine sounds funny too. I checked the following: Blow off (switch valve) ok. Charge pressure control valve n75 ok. Charge air system on tightness ok. have already installed new ignition plugs The error memory also gives no information, sometimes the throttle valve is in it, and namely throttle valve potentiometer unplausieble signal (but he had that from the beginning and it is not always in it) Furthermore, I have the measurement value blocks of the L MM read out, but these don’t go higher than 70, can it be because it doesn’t run properly and doesn’t build up any pressure? Please help me to reach icq too, NR: 179042367
