I am having a e39 528 yr 2000 model. the radio was fine before servicing my car but after service, my mech told me that the radio can't work becaus kena aircon water! well i think it is totally bull so i insist him to open the radio and try to check the connector and out of suprise, the radio suddenly works again!Yesterday while i was driving, the radio died on me again!!! hmm....has anybody having this issue before? i look at the radio the other day and the radio connector is fitting very fine and what could be the problem?????

For my experience if your radio connected with pre-amp and that pre-amp connected to main amp with low power, the system might be halted. When the temperature hot the system will cut off the radio source of supply which direct from battery to the computer control unit. This is why your radio will flat with silence.

Is that radio ON but no sound, or completely OFF no power to radio?

They must have over-stretched the cables or knocked some electronic connector out of place. Very tricky territory there.

You'll need to get a multimeter, a radio wiring diagram and then eliminate the possibilities one by one to find the culprit.

woh......start to get complicated already....

I have not really fixed this issue yet, and just by luck, open and close the connector at the back of the radio a few time, the radio come back to live again.

This after when i started to 'blast' some bass music, the radio suddenly off! i was knnccb but suddenly the radio come back to live again!!!!!

so now cannot play heavy bass music with high volume......

Dude... check if your bimmer has contracted Alfa Romeo sickness... the same stuff that makes the car "have character" or usually referred to as dodgy and unreliable.

Oh, all those love-hate relationships I've had with my Alfas

check the ground wire and the fuse holder to the radio (HU).

If either that or the HU is kaput. BTW, do you have keep in the "RESET" or "password" when the HU come back alive.
