Replacement Radio Head Unit after dead battery?

[robbieboy]

Hey guys,

I have a 2007 325i E92 (only done 100,000 km), which was parked in the garage for a couple of years whilst I was overseas.

When I finally returned, it wouldn’t start and wouldn’t charge.

To cut a long story short, after trying a number of things, I ended up getting a new battery and had the repair shop do the electrical repairs, reprogramming and coding.

They got the car going, but the radio head unit is still dead. I would have expected that this would have all come back on after the work they did, but they are saying that it needs to be replaced.

The unit was working perfectly when I parked the car in the garage 2 years ago. I just don’t understand how it can just die like that.

Do you think it really could be dead and needs a replacement? (If so, it’s going to cost a fair bit of money) or could there possibly be something else going on? Could a dead battery trigger this to die/malfunction? Or is it just a coincidence?

Thank you

I'm having the exact same issue. Dead battery that's been replaced, radio is completely dead. No display at all, tried a bunch of things. Let me know if you've found a fix please!
