Hi folks, Just a quickie .
I have a 2003 B6 Avant and would like to give the battery a wee top up charge as its getting cold but with all the electronics hanging off it......
what is the correct procedure to charge it.
Do I need to disconnect Both terminals, will it cause any problems if I leave them both on while charging. Could I get away with pulling off the Negative only ?
Any advice gratefully recieved ..I don't want to blow a module through stupitity....

Thanks
Mike
