Can you make the service reminder go out if you reset it manually or can it only be solved by the dealer?
For the sake of £360 (assuming that is the only issue) I would be happy to reset it manually each time, as it only takes a few seconds. (check the forum for instructions on this).
As TT says, might be worth going down the route of speaking to VW warranty/technical to see if there was a software update.
As it would happen, I just had a new dash pod fitted (thankfully under warranty). Different issue though, the highline display had pixel loss.
