I hope some one on here can help me I went to my mates garage with TC ABS lights on used his snap on scanner no faults found but the lights went out now I get a noise from the front of my disco and the TC light comes on then goes out and filles as the breaks are comeing on then clears.

check sensors, might be dirty. may need resetting after you have checked.
one way to test which wheel is to lock up one at time on wet grass ect
