Disconnecting BMW immobiliser

Hi. After stuggling with an intermittent starting problem I am now down to trying to disconnect the BMW immobiliser. Does anyone have a wiring diagram for "CONTROL UNIT ALARM SYSTEM SYSTEM I 82119401487" (Realoem). Or any pointers on how to bypass it.
Thank you.

Hi Richard, please see attached.... according to the Electrical Troubleshooting Manual there are two systems (Alpine and DWA IV). I have extracted both for you which is from the 1995 manual. The Manual is not M5 specific.... Real OEM part you quote I believe is the retrofit kit. There is also Part Number 65 75 8 366 229 - DWA version which is the updated part number 65 75 8 355 139 for the control unit. I hope this helps you.

Steve

Thank you. I actually found a spare alarm system with the same part number and tried that but it didn't cure the problem. I will trace the wires just to check the connections though.
