Oh no, new owner same problems!

After a few weeks with my Z4 I have had the dreaded bong!

The roof bong! Everything seems to be working ok, yet when you start the car the roof bong happens but then disappears after 5 mins?

Hit a bump in the road and it came on again?

I have tried searching the forum, and luckily the car is still under warranty, but any ideas, has this happened to anyone before?

Thanks in anticipation.

probably any one of the many sensors in the roof mechanism

Cheers. I’ll try and get a bmw diagnosis before taking it back to the garage

Why? Won't BMW charge you for that?
Just take it back under warranty and let them bear the cost.
