I've just had this issue with my car.
MOT failure as ABS warning light was ON

Recently sometimes the ABS warning light comes on, then just goes off from time to time.
Cost me £65 for a diagnostic test to reveal something is wrong with the rear-offside system. Could be the toothed wheel, sensor unit, sender box or system wiring.
Cheapest potential solution £312 for fitting a replacement sensor unit, worst case scenario was fitting a replacement toothed wheel kit at £1200
Let me add that this is an error code dashboard light.
The brakes function correctly and exceed all MOT and safety aspects. The ABS system is working..............but the warning light comes on and goes off from time to time.

Very frustrating situation.

I always use my local garage for MOT's and repairs, but they just couldn't access the ABS system to read the error codes due to software blocks. That's why I was forced to use the local dealership (stealership )

My local garage told me that they MUST test the car as presented so I waited and waited until the ABS warning light was 'out' then took the car down for an MOT test presto presto.

As the car was being moved on the ramp the darned light came on again. Fail
As I was driving the car home the light went out again, so back I go to the garage.
This time the light stayed out for the duration of the test.
MOT PASS

That warning light stayed out the whole of that day and the next.
Over the weekend it came on again, Tuesday went off and yesterday came on again.

Graham if you have any words of wisdom on how to stop this darned warning light from causing such stress, please can you share ???

I have no problem to spend £300 if I really really must, but it was such a frustration and stress with the timing of MOT.
I do have a problem to spend £1200 if the 'system' needs replacing.

Any help from the pistonheads out there much appreciated.
Oh BTW, any break in circuitry will cause the warning light to come on. (so just disconnecting the sensor will not work)
Removing the tiny bulb in the warning lamp will cause the ETS warning light to come.
