Cabrio roof recommendation

Anyone know of somewhere that are good with a cabrio roof? Not the roof material but the mechanism.

Ive an 05 A4 Cabrio and the roof is uneven. It closes down fully on the drivers side but the passenger side sits up between a quarter and half an inch. You can see when it comes down, at the point the drivers side makes contact with the top of the A pillar, the passenger side is noticeably higher. Both latches are operating but the passenger side the roof sits out of the channel .

Its something I've lived with since I got the car about 15 months ago and always created wind noise at motorway speed, but now its starting to regularly throw a "roof not secure" error on the dash and beeping loudly every time the car stops moving and starts again. A quick shove on the on the top at the passenger side sorts it for a bit but I want to get it fixed.

Is there anyone in Ireland thats seen as an expert with this sort of thing?

EDIT, Im also very much in to DIY'ing it if someone knew it was a case of there being an adjustment built in to the roof mechanism.
