Just starting on this (again!) and would really appreciate some advice. The front panel was repaired within the 3 year warranty period (by Preston VW Van Centre where we bought the van new in Sept 2010), but is now showing corrosion coming through again. Is it best to contact Preston, which is 50 miles away and a bit inconvenient, Grange-over- Sands VW dealer (where they sell and service vans, have some experience of Californias, but don't sell them), which is nearby, or VW Customer Services direct?
Am I right in thinking that they will check the main roof panel if they accept responsibility for the front panel, if you so request? I'm a bit nervous about pulling back the rubber seal myself having tried fairly gently.
Many thanks in anticipation!
