My local VW garage mentioned that they had a software update for the parking brake when providing a quote for my 3 year service. Trouble is a non VW franchised garage I use for another car is offering to do the same service for £200 less but they are not up to speed on this update. My parking brake is working ok as far as I know. Has anyone had the upgrade and is it necessary etc as the information on the VW site is crap. I am having the service done by the non franchised garage of course! Thanks
