Your first Mercedes 300D. YOur car may be operating and driving normally. These are a different beast to dirve than any American car you have driven. First your turbo gate does not open until 2000 RPM. So you will notice this boost at 2000 RPM. MAKE the car shift to get the engine in the 2000+ range. You pedal has a downshift switch. Satrting at a light I floor the pedal. As the rpm's incresase I may let up opn the pedal but not much. This will be the first car that you dirve where you floor it all the time. If at speed and you want to accelerate, press the pedal to the floor and force the "downshift swithc" to downshift the tranny. Dont' be afraid to drive the engine hard, they like it. As I said you want to keep the enigine in the 2000-4000 rpm range for best acceleration.

What he said, if your not flooring it daily your probibly not driveing it hard enough and building up carbon. Diesel or not, they like RPM. I'd be afraid to trust the governer to keep it from over-reving, or the trans, but there not *suposed* to let you.
I know with the shift lever in 1st mine will shift to 2nd on it's own anyway with enough RPM. Learn the feel of the shift gates and beware there is no safety lockout to keep you from nuatral or reverse other than the gates.(which is a fine thing in my opinion).
