The clock on my A6 seems to be gaining about 1 minute every couple of weeks or so which whilst not serious is irritating, Before I head off to the dealer to get it looked at does anyone know if this is something that can be corrected with a simple adjustment or will it require more radical work? Cannot understand why UK spec Audi's do not use the RDS radio to control the clock (or indeed the UTC time feed from the satnav).
