I took my car into main dealer a few weeks ago, as sunroof wouldn't close. When I picked it up it had a two feet crack across the windscreen. They said I dropped it in like that. I would have seen a two feet crack, but I shrugged it off and got it replaced under insurance. Today I dropped it off for first service, oil change and filter, and they rang me to say they broke the oil housing, and it's an eight hour job to fix. They give me a loan Mini Countryman. It's a G31 540i. They say the oil change housing is commonly damaged; has anyone heard of this before?
