clutch slipping?
Have a used 335i for last 4 weeks now and got a proceed. When I enable the Proceed i think the clutch slips under full throttle. I full throttle going about 60mph and the rpms jump about 500-750rpm and then drop down and the car accelerates? I've never seen a clutch slip for 500 or so rpms and then grip and be fine. Anyone shed some light on what is causing this? It has been a while since I have felt a cutch slip so I am not sure if it is slipping in this case or something else is going on. I am think of shooting some video of the tach if need be.

Ah I figured it out. It was the DTC kicking in. I was turning off DTC by pressing the button and getting the DTC light on the dash.....but that only turned off DTC at low speeds. To completely turn off DTC you must press and hold the DTC button until you get the circle light on the dash. End of problem.

You should make sure its not your clutch though, because as you described it that is what happens when you clutch slips. Easy test: on the hwy, put it in a high gear (4th or 5th), starting at low rpm, floor it, if you see your revs jump with no acceleration, then drop back down and then your car accelerates, your clutch is on the way out. This happened to me at ~21k miles. Problem is that it is hard to replicate without the Procede, but the dealer was still able to.
