I am desperately searching your help and advise:
I own my Turbo R ´91 RHD VIN SCBZR04A5MCH35051 since 8 years now, however, I only had a chance to drive it occasionally. Many times in the past, I had removed the battery and connected it to my Ctek charger. Never had problems reinstalling the battery.
This time, putting the battery back into the Bentley, an alarm sounded, which I even didn’t know I have. After going through many of the respective posts here, I confirm, that I have the Alarm ECU under the top roll. I have taken it out and confirmed, that the installed battery was dead. No leak, no damage to the board. So, I have replaced the battery with a new one, put it back to the car, connected the car’s battery – and: the alarm siren under the right hand front wing went on: beep beep beep …
The switch in the glove compartment is in ‚isolate‘ position
I don’t have (never had) the Remote Control ECU in the luggage compartment behind the right hand side panel. There is only a wire loom and two connectors connected to each other, very similar to these of the Alarm ECU under the top roll. Neither do I have any control key fobs.
Interior lights are on, I can switch on the head lights, I hear the fuel pump priming when I turn the ignition key, I can hear the gear actuator working when moving the lever, however, the starter doesn’t move, no noise of any relay, no nothing. I have the resistance of the key when tuning to star, but nothing happens.
I have checked and cleaned all fuses and relay contacs.
Next, I have bridged the two white / yellow cables of the Alarm ECU, hoping this would bridge the burglar immobilzer – obviously, it did not ?
My questions:
Your feedback would be greatly appreciated.

My questions:
- how do / can I disarm the factory installed burglar system without remote control key fob ?
I could disconnect the siren wiring – this, however, would not solve the immobilation of the starter and bridging of the white / yellow wires going in and out of the Alarm ECU didn’t either.
- why this alarm / immobilisation of the starter never happend in the past ?
- which wire goeas from the Alarm ECU tot he siren – can I disable it ? So, I could continue trying whithout removing the siren from under the wing and without enoying the entire neighbourhood.
Your feedback would be greatly appreciated.
