Hey all,

I got in a e60 2005 530i recently that was stone dead apart from doors unlocking, parking lights, hazards and steering and seats adjusting.

*Terminal 30 show 12.83v
*Terminal 15 remains dead regardless of position of key
*Cluster Dead
*Radio and Idrive Dead


I can connect to OBD and access the various modules but cannot activate anything that relies on Terminal 15


DME Scan reveals:
1) Battery voltage 62.89v
2) Code D904 CAS K-CAN line fault

I discovered that the alternator cable was disconnected - attempting to reconnect resulted in a shower of sparks - alternator dead short

Even with key off - something is holding the DME open as the idle control valve continues to buzz.

What I have done:

1) Left alternator disconnected
2) I swapped out the ignition key sensor (screwed to back of switch) - no change.
3) Checked all fuses and relays
4) Disconnected IBC
5) Disconnected MPM
6) Swapped out instrument cluster


My thoughts:

1) One of the modules is corrupting the K-Can Line
2) CAS/EWS/Key is faulty and not activating T15

Your thoughts?

Cheers

Andrew
