During a long drive yesterday prior to winter hibernation the ABS warning light came on after stopping to fill the fuel tank. It went out after 5 minutes. Checked and cleaned the contacts on the electrical relays on the hydro unit once they had cooled down, (they were very hot) but nothing visibly wrong. Moved the car this morning and all seems to be ok.
Tried to lock the brakes on the road, but failed, it just stopped very quickly as expected.
I believe a lit ABS and/or traction control warning light is an automatic MOT failure ?
Anything else to look for or is this a BMW dealer analytical system check.
