Ok, so this is a strange one. My (factory) radio loses all reception but still shows the station, only when the engine is on! If I press the window button it comes back but only if the window is up or down (not while going up or down). From all I've read it sounds like BCM/BEM as my battery would die after a few days if I didnt start it so often too. Any help would be greatly appreciated.

Not sure on this one but clean and inspect all your earths including the ones on either side of the dashboard.Check your charge rate and make sure the drive belts are tight.Charge up your battery using a decent battery charger because just starting and running the car isn't going to give the battery enough charge.ok ?Kevman.
