Changed new front pad/rotor/sensor but reset shows 16k mls left???

Hi Guys

My front brake pads would usually show me 50K miles left when the dealer changed the pads/sensor out last time. That was several years ago. Now at 89k miles, the front pads were due and became overdue by 2000 miles. So I went negative 2000 miles (service due since...)

This weekend, I changed the front rotors, pads, and sensor then used the BavTool to reset the brake remaining life.

When I did that, it gave me only 16,000 miles!? How can that be? The rear sensor/pads that I replaced last week reset at 23,000 miles. We know the front pads last longer than the rear.

Also, I bought the sensor from eBay from a trusted vendor who sells BMW oem parts. So is it possible that the sensor is faulty? The sensor did look new and showed no wear and had life.

The bavtool has an option to "reset mileage to a specific value". But if I do that, I'm thinking that I might screw it up and trigger a "replace brake" warning again and have to "short" the two wires to get it to reset?

I suggest you just relax and let the system settle out. Going negative 2,000 miles probably messed up the calculation of the estimated pad life. All you need to know is when the wear sensor gets spent, it will trigger the indicator to change the pads. You know you have fresh pads and sensors, so there is no need to worry that the brakes are going to go past due. Once the sensor gets through the first stage, it will probably correct the mileage estimate.

Did you try resetting it using the stalk?
