Hi all first post !! Just purchased a 60 plate C180 and love it. Just 1 problem , the command works fine until you put key in then only works for about a min then switches off and does not work again . Read through posts and google can't find any help . Phoned the last owner and he said it started doing it intermittently with him he said "Pre-Safe not working see manual " warning on dash started to appear about the same time and thought it might be linked? Read people talking about taking fuses out but not sure which ones to try ? Thanks for any ideas or help Martin
