If you own your car I would stop dumping your clutch at 6K, your putting alot of strain on all of the power train system (Clutch, transmission, XDrive system). I mean you have a warranty, but no car deserves or can with stand that kind of abuse. I would also get an extended warranty to cover the car later on down the road. BMW will mostly know what you have been doing so i dont know what else to tell you. You can keep dumping the clutch at 6K and see what happens
