Hi, does anyone know how to remove the central air vents in a mk3? I've got a broken slat on the left hand vent and have the part to replace it (don't ask how it was broken but it didn't involve a stiletto heel!). Looking at parts on eBay the whole surround with both vents comes out once the head unit is removed but there looks to be clips and I don't want to damage it or the dash. Otherwise it's a trip to the dealer or an independent (if anyone knows a good one around Manchester). Thanks!
