Sorry I'm don't really know how to post on this forum properly so replying to my own thread!
My van is still as the body repair place, and still not had a yes/no response to my claim to VW customer services for a new pop-up roof from VW - being given the runaround despite being assured they would get back to me within 24 hours of 30th April...
Have seen several comments from people who have been happy to have their pop-up's repaired/resprayed, and I'm amazed! - Corrosion once in the aluminium will always reoccur!?! It would be completely unacceptable to have to buy a new roof in a year or so's time (as I'd then be over the 6 year 'paint' warranty) Nobody would buy a vehicle that had only a 6 year lifespan without having to replace the roof, whether it was a cheap car or a £40,000+ camper van. I have no intention of letting VW fob me off with that - Watchdog/Dom/The press will be my next port of call if they don't fully replace the corroded roof and give a full warranty to the repair... SHAME ON YOU VW
