Thank you for the tip!


I presume I need to remove the sensors to clean out in there. Are we thinking compressed air or will brake parts cleaner do the trick ?

I once had a wheel speed sensor going bad and it would randomly put me into limp mode. Was that happening to you when you lights came on? If I recall I couldn't go over about 4000 rpm.

Either way, I've had a rear sensor go bad for no apparent reason. Consider logging some wheel speed data and see if any of them are doing anything wacky. I my case, one sensor would give a couple intermittent readings that were way lower than the other 3 and causing the lights to come on. The issue became more repeatable as my speed increased.

I'm not sure - as soon as the dash lit up I putted back to the pits and parked it.


Thanks for the wheel speed tip!
