Another update...
This happened to 3 of my wheels
Blatantly the wheels had been repaired (badly!!) prior to me collecting the car.
Several phone calls to the supplying dealer (350 miles away from Newcastle) ensured that a goodwill repair was agreed.
The car went off to the local Lloyd's body shop and a full refurb was carried out (tyres off, wheels dipped / blasted, powder-coated and lacquered)..... all free of charge
Must be £400 worth of work for nowt!!
It also meant I was able to get my tyres changed on the rear - got some 5mm Dunlops off eBay for a mere £80 - should keep me going until after the Winter, when I will remove the Runflats and go for normal tyres
A slightly better picture..
Also, tried my £100 e-Bay bargain 1M xenon to see if it works (it does!) but just need to figure out the work involved now to get the eyebrow to light up....
