My guess is that most Vw trade in the UK is three year pcp. The extended warranty will be underwritten by a UK insurer, maybe even actually fully provided by one. For this deal to work, the insurer will be looking for volume and I don't think Vw UK customers are providing this volume because of our love for pcp
Volume might play a part for pulling it (a VW UK decision, as VW GmbH are still making it available for other markets), but the factory extension is (was) provided by VW directly- you could only spec it prior to delivery of your car. I recently had an extended warranty claim on the Golf - there was no authorisation required through a third party for the VW confirmed fault (complete loss of DAB signal). Work was authorised straight away and parts ordered immediately.
I wouldn't have though any more people buy Audis for longterm use than VWs, yet you can still get a factory warranty extension for your soon to be delivered Audi. Same parts, same likelihood of failure on that Audi.
I'm going right off VW for the way customers are getting treated aftermarket.
1. VW knowingly sold me my Polo with a safety design flaw middle rear seatbelt likely to detach in full occupancy (3 in the back). They were aware of this issue in April 18 and carried on building MQB A0 designated cars with the issue until October 18 (mine included). In the meantime, I was not informed not to use the middle seatbelt until a recall notice was issued in Feb 19.
2. Go to a dealership now and you're warned of the potential to be hit with a £60 diagnostic fee if they can't prove your reported fault. VW UK clearly aren't covering the diagnostic cost for a fault the car doesn't log anymore. The burden of proof lies heavily with the customer. I have an issue now with our Aug 18 Polo GTI+ - about half the time the car is started from cold, the virtual cockpit doesn't fire up, so I'm driving with no indication of speed. I have videoed the fault to safeguard me from the £60 charge when it goes in for diagnosis and fix next week.
3. Ask for a courtesy car now for a warranty claim and many dealership groups are now charging admin fees that amount to full blown rental charges. VW UK clearly aren't supporting the cost of maintaining a courtesy fleet for warranty purposes. My local Looker group want £12 a day "admin fee" for their "free" Up! courtesy cars, plus £5 a day "admin fee" for insurance.
The Lookers Audi dealerships don't charge, so I'd assume that Audi UK still contribute to the courtesy cars for warranty use.
It seems that VAG are trying to widen the gap again between the VW and Audi aftersales experience, not by making Audi better than it was, but by making VW worse than it was.
