At the mo my car is on finance too but I intend on paying it back sooner so I can own outright. Hence no mods on the car until then, which'll hopefully be in 10-12 months time.
I've heard of some dealers not twitching when Revo remaps have been mentioned. Is VWUK likely to be in the same boat as SEAT uk? Especially given that they're all part of VAG?
This is also one of the reasons I had against buying a mkv. If I bought a mkiv GTI, I could get it serviced locally for a cheaper rate and still be able to modify it without hassle.
....I bought my car for cash outright, no mucking about, but I still discussed my wish to remap with my VW dealer
before doing so. They asked who....I said Revo....and they said no problem. They have absolutely no problems about any of my other mods either - They have even fitted some of them! The only warranty issue they couldn't resolve was the white worm on my 18's and that was only because my car was registered with VW UK with 17's - They tried and I tried direct but we couldn't do anything about it.
Their attitude is that I'm a friendly and very understanding customer who is totally honest with them and they do all they can to support me and they really look after me well. If I published some of the stuff they've done to help me, I might get them into trouble!
VW UK can be very tricky though. The best way is not to rely on warranty income to solve any problems on your car. If you mod your car, think of a successful warranty claim as a bonus. There is one underlying legal principle in your favour and that is that the aftermarket modification has to be a
direct cause of an issue; BUT, you pay first and argue to get your money back after!
I hope this helps!
