You may want to consider leaving you car in gear when parked. This week I came out of the house to find my V40 D2 SE had rolled down the slope outside my garage and planted itself into my garage door! The result is body damage to the rear of the car and to the garage door. When I got inside the car the handbrake was still applied with the handbrake lever up as I had applied it. I parked the car the previous evening at 6:45pm and believe the car rolled into the garage at 10:30pm (3 3/4 hours later) when my daughter heard a bang 'like a car door being slammed' on the driveway. The car is booked into a Volvo garage next week so I will post what the response is. I thinked the brake discs released as the brakes cooled down - a common problem when disc rear brakes were first introduced. Not being hopeful I have also kicked off the insurance claim. :huh:
