However, I do know that from experience they can just randomly "lose" the connection to the speed sensor. I have only had this happen once though and typically it was on my way to the 'ring (and the first time I was taking the CSL), so I was reluctant to run it with out traction control operational for my first outing there in a new to me car.
I was really lucky (like Craig) that there was a guy there from Scotland with his own E46 M3 who was a whiz with INPA and had his lap-top with him. He plugged it in and immediately diagnosed that it was one of the wheel-speed sensors, where the DME had somehow become confused and decided it didn't want to communicate with one of them. He reassigned it and it's never been a problem since (and that was 8 years ago)....
Total cost - I had to give him a passenger lap  . |
Mine would reset then soon as car moved went off again, so trailered back to my house in France, by the very helpful Delta racing on there way back to Gurnsey
