So...Quick update.
I had a call yesterday while the car was in Heritage VW (Yeovil) and they told me that the wing and boot lid had been previously repaired due to the paint thickness being uneven and thinner where the bubbling has appeared. i fully understand that they cant repair it under warranty because of this, but how do i know that a previous owner hasn't had VW do it under warranty before? and the rust is coming back due to a bad job done by them...?
Anyway, so i got to the garage and when i got there i asked to speak to the technician that carried out the work and he explained all of the above in 'slightly' more detail. when we walked around the car i noticed a hideous scratch on the left front wing and asked the chap if he noticed that before he started and he agreed that no, it wasn't there before.
I'm now waiting for a call from them to let me know how this will be resolved. so i might have a saving grace in that i can offer them to knock off the expense that it would cost to repair the scratch against the cost of a new wing to be sprayed and fitted.
who else has had this? because i seem to remember that pretty much everyone waits a few weeks for 'results' to come back as to whether its going to be under warranty or not.
