Hi all, Just wondering if anyone could shed some light on my weird cars fault and why it could be doing this?? I have a 2003 e46 m3, currently looking for a battery drain issue atm so ive bought the hedgehog to replace (doing today), and while looking for the drain ive noticed that if the cars completely off and im sitting inside with keys out, i turn my lights on and the radio comes on!!!! Wtf! Could this be down to a bad earth somewhere?? Also, this has only just started to do this, wondering if somethings getting worse with the wiring.. Sorry for the long winded post but its bugging me sooo bad. Lol. Thanks. Scott.
