I had swithered about just going to a garage, but the chap at BMW said if I fit the part propertly the computer should pick up the part and reset the fault light for the brake wear sensor.
Can anyone confirm this? Is there a best place to buy the brake wear sensor to be sure the Car Computer recognises it?
Any advice would be appreciated.
Thanks again - great responses - helpful forum.
Yup the car will detect the replacement sensor. I've always bought mine of E-bay and never had a problem yet- they're a fairly simple electrical contact which completes a circuit when the caliper moves sufficiently towards the disc so there ought not to be anything particular about which one. I've yet to buy one for my 1-series but by 6-series were about £12 from memory.

p.s about £6 on E-bay so if you can get a BMW OEM part for £7 - go for it!

Got some work done at the Garage for the MOT, but the lights are still on (amber) for brake stability. Had a look at the break wear sensor, tried to remove the one that was in place (front offside), but couldn't get it to budge., Any ideas?

Which end? Disc or connector block?

Yes

They're embedded into the pads themselves so when you replace the pad you're also replacing the wear sensor, (which is basically just a metal rod with a wire at the end of it), as the warning light is a result of that rod touching the disc to earth it against the car and complete the circuit.
Sure?? (It pains me to question your impeccable electrical credentials :roll: ).

On E38 and similar you can get the brake sensor warning to go off by just turning the key to II and back three times (provided you have put a new sensor in or just removed the broken one). Having a broken sensor as you called it earlier wont put the light on, it only cones on when the sensor touches the pad.

I'm not convinced the sensor is your problem. You can just take them off and see if you can get the light to go out, no harm in not having them fitted.

The sensor just unclips from the pad. It's a spade like fitting and just pulls out.

No they're the same. The 7 pad sensor just pulls out as well, I did mine a few weeks back.

When you buy new pads they don't come with a sensor, you can use the old one or buy a new one. Same on the E36 which I did last weekend. Have you got a funny variant or are we getting our wires crossed (no pun intended)?

Yep, don't recognise the diagram but the picture is right. I have only done E36 and E38 which is the same as the picture of the caliper you posted, on both the sensor just pulls out of the pad. Maybe the 1 series is different.
