Hi All,

Recently bought a Hartge H27 in the land of the rising sun, and wouldn't you know it, 4 days into ownership the long time inactive alarm/immobiliser decides to take a new lease on life.

Whilst I'm trying to get on to BMW in the hope of purchasing a replacement key, I am hoping to get around this problem another way. As most of you know, auto labour in Japan is ridiculous, and I am a little suspect about theyre know-how in this application anyway.

And yes, up above I said key, not remote. This BMW alarm has an extra key hole in the drivers door with a red LED. I'm hoping someone here has had a similar experience. I suspect there in no remote function, and that the alarm was fitted prior to original delivery. It really is quite well integrated. For example, the horn (not siren) had a security cage bolted around it to make shutting it up that much more difficult. The wiring for the alarm also ties into the ECU and body harness in numerous places. Also, the key barrel isn't an easy fix either as it is not of a mechanical nature (possibly magnetic) and is connected to the alarm module via a 14pin connector, which must convey a fully sequenced signal to the alarm module.

So guys, i'm looking for any way around this that you can suggest. Whether it be in regard to whether these keys are available, or simply where the hell the ignition relay is. I can smell fuel, so am hoping that a previous owner has rectified that immobilising point. Starter kicks, but I have no spark. It does concern me that the alarm module has lines going to the ecu though...

Thanks in advance!!!!!

I dont think it is ecu controlled on the e30's although I could be wrong you will have to find the alarm box and trace the cable and disconnect as and when and reconnect to remake the circuit I'm sorry I cannot be more help
Bollocks to this 24v scrap!
