Quick question for the experts - how do I re-program the immobiliser code ? The owners manual is missing in this car (something I also want to rectify at some point) and I didn't have an immobiliser or alarm on my other S1.
I ask more so that I know how to avoid accidentally changing the code through fiddling than some burning need to change the code right now
Also if I disconnect the immobiliser will it remember its code if I ever reconnect it ? Is the code stored in the immobiliser unit, the engine ECU, or both ?
One more question while I'm at it - where is the keyhole that enables the siren ? I noticed when I set the alarm off from disconnecting the battery the headlights flashed on reconnection but there was no siren...
