Reset brake wear sensor on 0, now get _ _ _ _ _ _

Post by 2ndclasscitizen » Wed Jan 10, 2018 11:18 pm

Hi people. I was waiting to pick the kids up and thought I'd look on youtube to reset the brake pads wear service interval. It had already hit 0 and kept popping up on the dash which was annoying so while I was bored sat in the car I thought it would be a good idea to reset it as I could see there was loads of meat left. Now every time I start the car I get the car on ramps and red brake service light on the dash which is even more annoying :banghead: .
Took it to a local 'specialist' in the hope they would be able to hook it up and reset it, however they told me it needs new discs/pads/sensors on the front, I don't believe it as I can clearly see the pads through the wheel.
I have done a search on here and believe that if the OBC has hit 0 on the brake service interval it needs new wear sensors? However, I've also read a post though that states the pad wear limit needs to be reset, this bit I'm not sure about... I've also read about shorting the sensors to trick the OBC as it needs some resistance so just wanted a bit of clarification before having a go at a problem that I created myself...

So, if I reset the on board brake pad wear counter at 0 and now just get _ _ _ _ _ _ _, will a new sensor/sensor sort it :? ? Is disconnecting the battery necessary to reset anything with it? Cars an '08 125 E82.

Many thanks.

You can't just reset the wear sensors willy-nilly, the car expects two wear events to happen in order::

You'll need one new front sensor now, disconnecting the battery won't help / isn't necessary.

Cheers marco-polo, it was one of your replies to another post that made me think I shouldn't have started played about with things... Just wanted to make sure in case I created further, unnecessary issues. The front and back both show the _ _ _ _ _ _ _ so I guess I'll need to do both then? I know the back were only replaced a couple of thousand miles ago and assume they are link together.

Thanks.

If the rear sensor is basically new it should reset correctly.

Was it a genuine BMW sensor? We've had loads of --.-- issues with cheapo aftermarket sensors which won't reset.

Don't know to be honest, it was done just before I purchased the car and I've only had it about 6 months.
