I own a late '99 318i. Of late, the sensor panel has become a little temperamental.
- The handbrake light comes on when the handbrake is clearly not engaged
- The seatbelt light comes on when all seatbelts are connected
- The seatbelt light stays off when all seatbelts are disconnected (!!)
- The Stability Control light comes on when ASC it is not engaged
Turns out that after driving for a while, these lights randomly return to "normal" - i.e. correct operation.
I am unwilling to believe that all sensors have konked out at the same time.
Also, now my brake sensor is on and it hasnt been turning off for a while - so I am not sure whether I need a brake pad change or whether it is another false alarm!
Any suggestions? is there a way to reset the computer / sensors and start afresh - much like a reboot??
