2005 A6 C6 sticky console switches
I've just purchased a 2005 A6 and it is suffering 'sticky switches' in the centre console that houses the handbrake and gear shift. I have a suspicion that someone in the past has placed a drink in the cup-holder just behind the console and that this has spilled over the '<', 'Return' and '>' switches, with the result that they all stick a little, and the '<' particularly badly.
Any suggestions as to how this can be fixed, since I suspect a replacement console will be expensive. And I can't see how to remove the swiches for cleaning, so guess this is probably not an option.
