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.

check the E34 forums... I know some 95 540 guys went through this problem before.

1990 525 Alpine Weiss, Miller MAF conversion, Eibach springs, and Dinan cigarette lighter.

1991 M5 Sterling Silber with TMS chip, SLS delete, UUC SSK & DSSR, M Tech EVO II Wheel, Eibach springs, RD Bilstein struts and Stebro exhaust.

1991 M5 Alpine Wiess slowly coming together with a rebuilt MAF, M pars and a B&B exhaust

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.
