Folks
Just returning from hols and ABS light flashes intermittently on motorway. Next day on a few short journeys - no flashing - any guidance would be useful - including ignoring it until it ever returns!
We returned last Saturday night which was particularly steamy if peeps remember and we we were on a ferry where the car deck was amazingly hot and humid - perhaps water penetration/oxidisation on the contacts?

Hi Paul,
I've had this happen and a good clean-up of the "Dragons Teeth" (ABS Sensor pickup rings) on the hubs often works. If they get a bit rusty and dirty, the signals can be a bit ropey and the ECU logs a fault. On the fronts, it's also a good idea to give the end of the ABS sensor a good clean to remove any muck from its pole-pieces.
A read and reset of the ABS ECU is not a bad idea as it can be quite a surprise just how mny intermittent faults it can collect over time. It'll also give you a clue as to which wheel sensor (or sensors) is complaining.
Disconnect the battery for about 15 minutes to give the ABS ECU a good reset. I'm not sure if this will clear the stored faults though.

The ECU clears faults as soon as you hit 20mph- as long as the fault is no longer present.
My guess is that one of the rings is cracked and/or running out of true. That's what it was on mine. It eventually shed the ring altogether and I had to replace the entire CV joint.
