Default break wear indicator bypass D2 FL

due to a broken wire on one disc I have run for a long time with the break wear indicator illuminated ; if I understand correctly this will no longer pass the MOT
at the same time I have had an intermittent vibration on the front which I traced to the pistons on one brake not retracting [ temperature would mount to 400C as compared to 150C the other side ]

as the pads were about half worn I decided to have them changed at the same time ,hence fix the indicator

well the vibration has disappeared ....but the indicator has not ! the best laid plants of mice and men etc


so after a read of our colour blind librarian's sticky I decided a by pass was the best solution , stripped out the dash and tried to find the required brown and black wire ; can I find it , can I **** ; plenty of brown wires , some with other colours on them, but no black ; maybe I am developing colour blindness !


has any one else tried this on on a FL ? or does anyone know another method ?

as we say in france M'aidez ,M'aidez

The spelling differences could be due to a number of things. It could be to do with the region of the world in which the article was written (colour in the UK, color in the US), it could be to do with the author not having English as their native language and spelling the word phonetically (ax-el v. axle), or it could be my favourite and that is a combination of laziness and sending TXT messages. Since the advent of TXT messages and the abbreviation of every word, fewer people care if they spell things correctly or not, and will use the excuse 'they will know what I mean' e.g. 'break wear indicator'.

having tried without success to by pass this warning light I have read up a little on the reality of the MOT failure
having just fitted new pads [ not quite run in ] I find the following on a website called mottester

brake pad warning light illuminated is a failure......unless it can be seen that there is another reason

clearly that is the case here with new pads ......or is it ?

any comment appreciated

I guess that depends on the individual tester.

Assuming the problem is in the ABS sensor cable assembly and not the body harness, it would be possible to make a plug n play adapter that sits between the two connectors which completes the pad sensor circuit.

Or of course trace the fault in the wiring and repair it. Its usually corroded or loose pins in the connector at the caliper or the other end where it joins the body harness. I've seen one with a break in the cable assembly - if its got alloy hubs the ABS sensor assembly is cheap enough.

I meant to look up which connector it is on the cluster but I forgot sorry!

tks again mikki , but I'm not clear where the ABS sensor comes into this ; I'm aware of cars where the pad sensor is combined with a handbrake sensor but didn't think this applied with on the D2 ...are you saying that the ABS sensor is combined with the pad sensor in some way ? there is no ABS light illuminated
