BMW E60 525i 2006 - Radio downloads 7A, iDrive - black screen

Hello everyone,

car bought a week ago, the previous owner took out the fuse responsible for the radio (F34 from the fuse console in the passenger compartment), because the radio consumed electricity all the time despite turning off the ignition. Except for the backlight of the radio and its fan on, the radio and navigation cannot be used.

I measured the current power consumption of the radio and it is 7A. All other fuses (both in the passenger compartment and the battery) measured, all functional. From the initial search for a solution, I bet on the CCC motherboard as the culprit.

Is there anything I should check before removing the module and trying to repair the motherboard.
Is programming necessary? If so, which interface and program should I use? I have an interface on RS232, INPA, NCS and DIS.

I intend to undertake the repairs myself, the service on site (Australia) wishes for the repair service PLN 3,000, buying stimulants from Poland odapa, due to the significant shipping costs.

I'm counting on your help.

1600 PLN radio + 120 shipping.

If in that money they would fix CCC, it's not so bad. Because it is an expensive audio system even in Poland.
All for around 10 PLN.

Don't overdo it - unless you mean new.

I gave up playing with shipping - too much risk and it is finally expensive fun.

I would like to fix it myself. If someone does it, why should I not do it with your help?

I have access to BGA and x-ray. I worked on motherboards from laptops in my time in Poland and I have experience.

If you have access to service websites or are able to write what to check in this case and what signals I would expect it would be very helpful.

Problem solved. Subject to close.

You're good.
