Hi guys, I've just been out messing with a new head unit in the mk5 which is currently parked up and it's nearly killed the battery, when trying to start it does the usual half a turn then all the lights go off etc. This isn't a problem as I'll just put it on charge but when I got out my remote central locking isn't working at all, non of the buttons have any effect. Does anyone have any suggestions on how to sort it?
Cheers
