Apologies in advance if this has already been covered, but I think this is a bit of a strange "problem".
The car is a 2006 Grand Scenic (Phase 1)
Basically, sometimes when the parking brake is applied, if you open the boot and close it, the parking brake whirs tighter again. If you open/close the boot again, it whirs again, and then comes up with "Service, Check Parking Brake", and the dashboard beeps continuously. The fault disappears then after about 30 seconds or so.
This doesn't happen all the time, however, I am a bit concerned in case the unit is beginning to fail.
Also, most of the time when the parking brake is applied, once it whirs, there is a click from the back of the car, presumably from the braking system?
Also, if you start the car with the brake, the handbrake whirs tighter too.
I was wondering if anyone could tell me if this is normal behaviour? Or is it a sign of something about to go majorly wrong?
