Looks like I have messed up my post -sorry for that
I have read a lot about E60 M5 clutch problems on this forum, although haven’t found any post corresponding to the one I am experiencing, so I created a new post. I own a 2008 M5, EU specs 80’000 km, spirited driving – rear tyres ARE consumable. Never used the launch control. Very happy about the car (although 200HP short or 500KG too heavy).
For a few month now, there is something slipping when I accelerate. This happens essentially in gear 4 to 7, above 3k rpm. It’s like a quick declutch, letting the engine taking about 500 rpm while the car accelerates a little, then gripping again for a full acceleration. The symptom is the same in p400 and p500 mode, with or without the TC. I’d tend to think the clutch is dying, although when fully accelerating in gear 1-2-3, I “seem” to get full power and full traction and don’t really feel such slippage even flat out on P500. I’d expect to get rather more slippage in lower gears where the transmission is in principle getting harder punishment if it was the clutch.
I have no error message, the only issue I recently had was with a lambda probe, that I just had replaced. I have re-calibrated the clutch several times. I don’t see any difference if engine is cold or at temperature. It doesn’t smell anything but rubber after a hard drive.
So the questions is, has someone ever experienced similar behaviour? If so was this diagnosed as a failing clutch? Could this possibly (hopefully) be an electronic problem?
Any advice or feedback is welcome!
