Agree that pad change intervals depend a lot on the driver.

But at the same time, I wouldn't put any stock in the computer reading until it gets closer to the pads being worn out, or at least half worn. The brake pad sensor is a two-stage sensor on the E70, with a trigger for partly worn, and a second trigger for time to replace. Apart from those hard-wired triggers, the computer estimates mileage (for the distances between the trigger points) based on brake usage. I think the default at the start is 60,000 km on my 535. After 3.5 years of driving (with no hard brake use) the computer is still showing 60,000 for the fronts. When it hits the first trigger it will jump to a half-life measurement. My rear sensor is showing around 30,000, even though the rears are worn less than the fronts.
