Hello, I have recently finally replaced the throttle valve, since then the Dpf regeneration lasts only 10km. But: The first km after cold start stutters the gas acceptance, not as violent as with the regeneration with the old flap, but every time after cold start. If I give a little bit more gas, it is short away. At over 70km/h no tingling, the engine is absolutely never warm (different from the old flap). The speed does not fluctuate. When changing, I noticed that the In addition, the left vacuum hose from 120km/h has slipped down to 100km, where the turbo fails. With a mini cable tie it remains on it, can it be that too much pressure is built up? Is it simply the intake air temperature sensor(31216702) or the suction tube pressure sensor(31216185,8670292)? Or does the whole thing come from a different sensor. Coke EGR flaps (have never been cleaned, but do not travel short distances). Last guess, the air mass meter ?
