Hi Jappo,
Sorry for starting my thread in your topic. I'll get the hang of this eventually.
I contacted the factory today and discovered that wheel arch detachment has been a common problem recently. Dealership confirmed this. The solution is to take it in (booked for next week - 24 hours for the Glue to set before sealing the edges)
Apparently they have to take the liner off completely and if not servicable, replace the liner.
A Two part adhesive is used to attach it apparently and sealant applied around the edge.
I presume the problem could appear on all recent Mogs of all types, not just trads. It may be worth a look at yours ?
Happy Days and Thanks for the use of your thread.
