Hello

I have recently bought a 1996 S320. I am experiencing confusion with the electronic engine immobiliser. According to the handbook, it should only engage when the car is locked with the remote control. However, it seems to come on whenever the engine is turned off, even if the key is still in the ignition. I then have to lock and unlock the car with the remote control before the engine will re-start (even though I am sitting in the drivers seat!). Sometimes I have to do this twice.

My dealer has checked the circuitry and says that the device is working correctly. My request is simply this: Does anyone have any correct documentation for the immobiliser on a 1996 S class, so that I can clearly understand when the device will engage itself.


Thanks in anticipation.
