E46 Electrical gremlins
Discussion
Hi guys,
A few weeks ago the outside temp sensor on my E46 330i went haywire and started to give a wide range of false readings, usually either plus 50 or minus 40 degrees. Last week it started to change it's mind virtually every second, usually reading a very large negative number and beeping loudly each time it changed (presumably the frost warning kicking in).
I was going to leave it until the next service but tonight the traction control light came on and won't cancel. I don't know much about the technology in the car, could I be looking at a new ECU? Happily I think I have a couple of months' warranty left on the car...
