Hello again. I hope you can help me. I have the following problem: As soon as the charging pressure indicator is in the middle and the turbo should be in use, it accelerates enormously power – it accelerates much slower than it should. Sometimes it is also short. Error code is not stored. What could be the cause? I think of something like solenoid valve for turbo control (N75) but measured it and the values fit. Membrane of the wastegate works.(tested with pressure pump) Mention the car still runs normally in idle run. Also when driving as long as the effect of the turbo does not use. Recently it was completely maintained…. was made: *Service incl. oil change, petrol filter… *complete ignition system new *dish belt incl. water pump *all vacuum hoses new *complete charging air penetration new *new air mass meter *new camshaft sensor *new turbo (18T) *crank housing ventilation incl. all hoses new *dail seal new, exhaust manifold seal new *complete charging air seal new *complete charging air seal new *new air pressure meter *new air meter *new air meter *new air meter *new air sensor *new air sensor *new air sensor sensor *new air sensor *new air sensor *new air filter *new air filter *new air filter
