Anyone found RHD foot rest ?LOL... I'm surprised at Kidlington, I thought they were a little more switched-on than that.
Personally, I got mine from VAG parts (http://www.vagparts.co.uk) - probably cheaper too.
These are the part numbers they use (no guarantee these will work for a VW main dealer):
Parking brake: parkbrakepad
I'd go with VAG parts, they're very good and friendly.
