My park brake malfunction light came on after I swapped my tires (summer to winter on rims) yesterday. It was ok after the job was done and drove about 20 km then parked for 30 minutes. Get into the car after shopping and noticed the yellow PARK light stays on before starting the vehicle. Manually unlocked the park brake and drove home. I called the SA at local dealer and was told that was triggered by the tires swap ( 1st time in 3 seasons on my '08 X5). Is that true?
