I've actually been phoning around today for similar. Mine is 3 yrs old at end of March so is due it's first MOT and it's 3rd service at 26k (previous 9k, 18k)
VW Cambridge quoted me £54 for the MOT and £192 for the service. Basically just the lubrication service and a visual check. Sounded steep to me so I phoned AMD Essex and they quoted me £120 for the service, or £205 for a full service which includes oil, oil filter, pollen filter, air filter, fuel filter, plugs and the visual inspection.
I've decided to go for AMD as I have read good things about them on here, and they seemed really helpfull on the phone. They are also fitting cruise control for me for £150.
It's a bit of a tough choice to sway away from a VW dealer as some people might be a bit funny about that when I come to sell it, but as I see it, it's probably going to be better looked after at AMD judging by all the tales of woe I keep reading about VW dealers cocking up various things and doing stuff like swirling washing your car even after being told not to.
Let me know how you get on.
