Ok I've managed to turn the immo off.
The problem is now i can't see the ecu through the obd2 port.
Any ideas?

Looking at the wiring diagram for this car, there's no K-Line from the ECU.
The ECU has a W-Line which goes to the immo box, then the immo box has the K-Line.
As i've removed the immo box there's no K-line path from the obd2 port to the ecu.
I'm wondering if i simply short the W-line to K-line it will work?

In case it helps anyone, shorting K-line to W-line does restore communication from OBD2 socket to ecu.
I'm not sure what W-line actually is and how it differs to K-line, but whatever works.
