Hi guys new to the forum sorry to start with a fault but I have bought a Quattro Sport Cab (2003) with a roof fault. The roof retracts as you would expect until one of the roof bars catches on the front part of the storage compartment. This prevents the roof folding completely away. It all appears straight & lines up perfectly when you put the roof back up. Not sure how to remedy this and have searched for any previous problems to no avail.
