brake lining warning!

Pull the sensor connector. Short it (the car side, not the sensor side) with a piece of hard wire. See if the symptom occurs.

There's a rear brake pad sensor isn't there? Change that?

yup i did. it's the front thats having problems when i turn the wheel full lock on the right no brake lining msg. in the obc

Why did BMW decide to put sensors on just the left front and right rear brakes? Why not all four?

Why double the trouble?

Check round the back of the lead where is runs past the strut. Mine had worn through - any more and the circuit would have been cut. Result: brake lining warning. Would account for the 'now you see me, now you dont' warning

I took my car to the self-serve wash Friday and blasted my wheels to get the brake dust off and to remove some bugs that had overstayed their welcome.

When I started off again and got about 5 miles down the road, I got the Brake Linings message. The brake pads aren't that old. This weekend I'm going to give it a peek, but I bet I find a wire broken or something like that.

I had a problem with the warning coming on too, then I realized that there is a connector in the passenger rear right by the place that you would place a jack stand. I noticed it was loose, so I unplugged it, made sure it was clean and plugged it back in again, that fixed my problem with the sensor entirely!

I would figure that all you need is one sensor in the rear and one in the front, if your brakes are working right, both the left and right sides of the car will wear evenly and there is no need for a secondary sensor in that area.

Good luck, hope this helps!

found the problem! when i had my suspension serviced they left my brake assembly hanging with only a piece of wire to support it. the wire that connects to the sensor was stretched and probably cut inside. thanks for d reply guys

I suspect that piece of wire WAS your sensor wire
