Well, decided to buy a couple of VW freewheels for the alternator & aircon on my T5 as the picture on the GSF website actually showed a VW original part. I didn't think it would be the VW OE one but I wasn't expecting the really poor copy that I drove to the Watford branch to pick up. The Watford staff were really good - when I expressed doubt they immediately responded with 'No problem, just leave them here' What would be much more useful is for GSF to specify WHICH supplier they are using for the aftermarket parts then you can make a better buying decision.
