Hi Bigbud,
The issue with the queue is the availability of a loan Cali. Each of the 4 approved repair centers only have 2 loan vans each and this is holding things up. The vans are moved around the country by VW Rescue, now contracted to the AA.
The backlog of parts is resolved, by all accounts.
I was 82 on the list before I said I didn't need a loan van, then it was 'can we have it tomorrow'!
If you can do without a loaner, then contact Cannock direct, and they will probably schedule your repair in almost immediately. They will need to check with the dealer you used to register the fault in the first place, but this is just a formality. I don't think they contact VWUK customer service, at least Heritage in Westbury didn't for my repair.
Once the job is completed and signed off by you, the dealer will issue a warrantee note to you for the repair.
