Hi All,
I have been having an intermittent abs fault coming up for a week or two. Fortunately, it was not showing when the car passed its MOT a week or so ago. Now it is on all the time. What I've done so far:
Scanned with Vag-com - front left abs fault - mechanical problem.
Cleared faults - comes on again after a few yards driving. Checked fault codes again. This time it was implausible signal.
Cleared fault. Changed both front sensors. Cleaned down sensor hole with cotton buds. Same fault after a few yards.
Checked wiring to left front abs sensor - signs of previous repair so re-repaired.
Cleared fault and it came back again. Sometimes it says mechanical fault and sometimes it is implausible signal.
So, I figure it is either the front wheel bearing, or the abs controller itself.
I don't have the special tool for the front bearings, so I guess I'll have to put it in to a garage for replacement.
Anyone have any other clues for things to check?
Cheers, Geoff
