On Friday when i left for work, my rear calipers also seized, it was -10, took the first corner out of the estate, hit a snow bump and my rear end kicked out, im glad ive been practicing on a deserted business park :lol:
But then the Traction control light was permanently on all day as was the ABS warning light. They were both off the next day dunno..
Im guessing it was the rear calipers having seized coupled with the freezing cold playing hell with the electonics.
