Hi all,Has any1 experienced something like this? It stays on after the ignition and the key is pulled out.It used to be once in a while when it did that. Now it has become more prevalent and I think that was what drained my battery after 3 days of not using the car. The battery is just 3 weeks old.Previous battery would be dead even after one or 2 days. Changed the battery as I thought it has been in the car since i bought the car 2 years ago so could be on its way out anyway.But the radio will turn itself off perhaps after a minute or so. And it will turn on but delayed when I turned the ignition back on.Only the clock would come up.Sometimes I can hear the radio blaring inside after the car has been parked for hours e.g. after work and my assumption was it turned itself on while being parked. Another reason why the previous battery was drained overnight.Some other strange thing happened was the indicator arrow inside the instrument cluster sometimes won't blink and the tick-tock sound was muted even though the indicators outside did blink. So strange...What could be causing this? Read over the internet about this E39 electrical gremlins, check the fuses both under the glovebox and above the battery but all were ok,no blown fuses. Today I changed the ignition switch at Bomin for Rm340 as I what i read suggested the ignition switch was faulty. Turned out it was ok but John couldn't refund me as he took the part from elsewhere and it was me who insisted him to change even though he advised otherwise at first.BTW this all started after I installed the iPod/aux adapter from ebay to bypass my CD changer. Could this be the cause?Any ideas fellas?All advice kindly appreciated.Cheers all.
