    Hello,

    First BMW, and from day one have had interference on radio if Rear Heated window switched on. Last week Rear heater packed up all together. Have checked fuse but it is OK. I could replace the window, but it may not require it as it may be a wiring issue.

    Any help will be appreciated.

    An arc/spark between a broken element will cause radio interference when rear demister is switched on Steve. My friend RichardP will confirm

    This is a pretty common problem in the E46.

    First the radio reception goes when the rear heater element is on, then the element fails. As far as I know the only solution is a new rear window. The only other likely failure is the diversity antenna amplifier in the C pillar, but that should not cause the heated element to fail.

    Of course it could be wireing, but the heater element would be my guess.
