Hello all. I have an E60 2003 Years 530D

Two weeks ago, the car battery ran out. I was able to run the battery after recharging. Then the black screen problem started.I hear disc noise. Starting-Turning repeats always. Disc eject button won't working.Lights on CCC working. I tried reset iDrive with eject mute combination. No response.


I checked on Rheingold Ista-D software. M-ASK or CCC doesn't see in control unit tree.Just I see M-ASK-GW and can reach functions(Read hardware number,change fan speed,show voltage) And I can reach to MPM but show fault's. Also on Ista-D I can check MPM module (Read hardware number,relays,show voltage). All fuses are OK.

I saw an error today in Ista-D "E184 CD / M-ASK / CCC / RAD2 / CHAMP -GW K-CAN line Fault "



Where should I start to check? My CCC is Dead or it's can be wiring fault or what?

Sorry for my bad English.
