    Red Brake Light and Red Car on Lift Light

    Like the title states, the read brake light and red car on lift light just turned on today when I started my car this morning. I looked at all the brake pads and they seem to have lots of life still in them. Do you guys have any idea what the problem can be or how to reset this light? I've googled and tried to reset the light, but still could not get it to turn off.

    That means the brake pad sensors went out...There is usually quite a bit of life in the pads even once the sensors go off...BMW purposely does it early bc almost everything they do is overengineered/overkill...Maybe a money grab for brake pads/sensors from the dealer who knows?

    The only way to get rid of the light is to replace the sensor with a new one (~$21) and then clear it in the dash options...or splice the old worn sensor and then reset

    Brake sensors. You can easily reset it (if you know someone with the proper BMW tool) The light will indicate it again after ~100 cycles.

    Do you have to have a special tool or can you reset it in dash?

    I have had this same issue abt once a year. And sometimes I can reset it with the BT tool and sometimes not, Not sure why. It's not the sensor, the first time I had this issue was a week after I had the rear pads replaced by the dealer.

    When you look at the service menu in the dash computer does it just give dashes ------?

    I had the dashes you speak of and my wrench was able to clear/reset it. Happens about once a year also.

    It might be a warning that comes up that is brake related. If the pads are fine its a warning that the brake fluid needs to get changed. I think the spec is every second year it has to get flushed.

    Pads still have a good amount left in them and the fluid was changed last year about 10k miles ago when I bought the car.

    Bavtec tool in the conditioned based service area, you should be able to bump out the service interval and help the light go out.

    Brake Pad Sensor --- Had the same thing happen to me. Car went in for service, completely fine on the ride home, next morning I wake up the same lights were on. Took the car right back to the dealer, rear-right sensor got damaged when they replaced my rear brakes.

    Replaced the sensor, lights went away

    I reverted to an older BavTech version 1.8.5.1 and it worked just fine.

    Interesting. I just replaced my lines on the M3 with stainless (great upgrade btw) - and I just got this warning. I am pretty sure the pads are fine, but the warning is for the rear pads, and they are hard to see without taking the wheel off. I am guessing this is the same issue - just replace the sensor, and all will be well?
