I have a 2005 M5. About 2 weeks ago I decided to be Nigel Mansell and turned of traction control, but the gear change setting to the max and had power on. After redlining it and changing gears got the engine fault, DSC malfunction and limp mode. Go it home which was a block away and turned it off. Turned it back on and it was fine. Drove it for a few weeks in power and reasonably hard acceleration and it was fine would have been a few redline gear changes but DSC was on. Then a few days ago did the nigel mansell setup again, everything max, DSC off, hard acceleration, redline gear change and got the DSC malfunction again….Any thoughts….All the other DSC malfunctions i have read on hear sound different….
