    Hi Chaps,

    Was giving the car a bit of 'run' over the weekend and up popped one of the orange brake safety lights. Its just a round circle with a half arch either side of the circle. I'm assuming it's indicating a problem with the pads but as I had the discs/pads replaced only 2 thousand miles ago they can't be low.

    Assuming it's a loose or broken sensor has anyone had any experience fixing one of these before? If I have to remove the pads and discs it's probably not something I am comfortable with.

    Cheers
    Leon

    Whip a wheel off and see if a sensor plug has disconnected itself or snapped or something. The brake sensors are normally shorted, so as soon as there is a break in the loop (pads warn and sensor wire has been worn snapped, then the light will come on

    front left side is where the sensor should be
    its only on the one side on my A3 so i assume same on S3.....very flimsy wire and could easily have broken

    Took it into audi in the end as it was chucking it down with rain when I got home, and I'm doing a 200 mile drive on Friday so wanted to be sure the brakes were OK.

    Nothing was broken apparently, all they did was re-seat the pads and give them area around the sensor a clean and the error display has now gone away. It's annoying really, that it's cost me 1 hour labour for something that isn't even a fault. Maybe they should have a sensor to detect faulty sensors.....

    Paid Finchley Road Audi £120 for 1 hours labour to 'fix' the issue with my brake warning light yesterday (which they blamed on poor fitment of the pads AMD did over 2000 miles ago!). 3 miles later the light is back on. So it's probably a dodgy sensor which I thought was the case in the 1st place (as the wiring is apparently OK).

    They are consistant I'll give them that. Consistantly rubbish in all the dealings I've had the misfortune to have with them.

    Why oh why didn't they just replace the sensor when they couldn't find a problem. I know the answer, it's because they don't have customer interests at heart. Had they told me they couldn't find a problem, I would have said do it. Now I've got a big argument with them to have and all the aggro that comes with it.

    Are BMW any better generally as I'm thinking of going the M3 way....?
