Hi All.
First post -Yay!
Anyway, just bought a 96 E220 Coupe (124) bout 3 weeks ago. Had a 94 saloon before that.
Just wondering if anyone recognises the behavior of the alarm/immobiliser:
(The windows have the silver sticker with "Fitted with Mercedes-Benz approved alarm system" )
Car fitted with the Mercedes Infrared locking system. Switch-blade key, one button to unlock/lock
Alarm is not activated /deactivated by turning key in passenger side door.
Siren in engine bay beside ABS, has 2 ultrasonics inside (boxy ones not the small round ones, passenger side one has a tiny LED un top)
Red led just beside parking brake release.
Firstly the siren does not work, I can arm the alarm using the infrared key, leave the windows open, as soon as I put my hand into the car the indicators will flash etc. I'm presuming the siren has had it.
Problem is the immobilser, works like this:
Unlock the car using the infrared remote, lights blink twice, doors unlock.
You now have about 30secs-1min to start the car.
If you don't start it in time, the indicators will flash and the red LED beside the brake release handle will turn on. (also if you move in the car the LED ontop of the Ultrasonic sensor will flash, as you move.)
Now, if you do start the car in time and are driving along, when you stop, and turn off the ignition, (staying in the car) you have 30sec-1min before the immobiliser will kick in again. Meaning you have to get out of the car and lock /unlock it. - Pain in the ass! Especially when you discoved this in one of those automatic/drag your car along car washes
Just wondering, does anyone recognise this alarm / immobiliser? is it normal?
BTW, it does not have the control box under the floor plate on the passenger side.
Cheers for any help.
