There is probably another thread on this issue that I missed, but just in case....
Speaking to a dealer this morning there has been an issue with the company that supplied alloy wheels to Burstner and Hymer in that some batches developed corrosion (looks a bit like worm trails on the alloy). They will be replaced under warranty, but there may be some people who haven't noticed the corrosion and their warranty is due to expire. In that case, its worth a check just in case.
