It is remotely possible an amateur mechanical friend of the owner replaced the rear pads, and I can believe he might have left the sensor wrong there but it doesn't explain the front brakes which I can't believe after just 30k would need changing in less than 5k. This why I posted about this something doesn't make sense with the cars stats. Well I will inspect and sort it out and report here. Sounds like a sensor may be worn ... but those I believe were replaced by bmw when bmw did the brakes.
I did 40k on fronts, 55k rears.

The sensor is not a 'meter' that measures wear. There are two contacts that get 'broken' as they wear- the computer int he car uses the first 'break' to adjust the multiplier on its internal wear calculation- then when the pad is fully gone the second sensor is broken. You get a "brake service due" red indicator for that.

As above, do not assume the dealer or whoever replaced the rotors or sensors as they were supposed to...
