There was actually nothing wrong with the brake pads. What they also found was a cracked shock absorber top mounting same side as the faulty sensor. In the E90, the front brake pad sensor is on the passenger side only whilst the rear sensor is on the rear drivers side. I actually thought it is on both front and both rear brake pads but its not.The service centre thinks that the front passenger wheel had a pothole impact that damaged the sensor and also the shock absorber top mounting. However, we don't remember the car ever having any pothole impact that can do this amount of damage, as it would have to be a very big jolt/pothole!In any case, they replaced both the sensor and L & R shock absorber top mounting under warranty. Now the idrive says the front brake pads only need replacing in another 25,000km, which is more like normal. Even managed to get the car back the same day. Just a bit worrying that the shock absorber top mounting is so fragile that a pothole can damage it???</blockquote>
