Hello to the diesel experts among you. I have the following problem since 3000 km: If I drive for a long time at constant speed e.g. in column traffic and then want to accelerate in 4th or 5th gear, I have no power. The engine then increases very hesitantly at speed. Only if I step the clutch and let the engine drop to idle speed I can fully accelerate again in the same gear. I would be interested if someone knows this phenomenon and knows how to it can fix. Greeting Holger
