Purchased a 16 Countryman ALL4 S CPO and noticed a popping noise when driving in the roof above the rear passengers door. Dealer said they have a TSB and corrected it. It did reduce the popping sound by 50%. They said next step is to contact Mini field engineer for direction.

If you experienced this please share if it was successfully resolved.

 

UPDATE: The field technician inspected and they will attempted to repair again today and tomorrow. If this doesn't correct, they will send to a bodyshop.
