Missus calls on the way to work today, stuck in the snow. I go out to rescue in the Z3 Anyway get her unstuck, wave her happily off as she drives into the distance.....then I get stuck ~x( Anyway after about 30 mins of rocking backwards and forwards etc I finally get going, but....... my ABS and traction control lights have come on???? Checked for any ECU faults and there are none. Left the car for an hour or so, tried again still no luck. So any ideas why getting stuck in the snow could do this? My thought is a sensor somewhere has got water/snowed up, hence why I left it to defrost on the drive. But still got the problem (although it wouldn't have dried off, just defrosted possibly) Other question, is there a hard reset I can try? Ie maybe the sensor has water ingress and needs resetting? Any help would be really appreciated, I'm really p***** off as I'm in the process of selling the car so could really do without lights on the dash!!
