Just wondering what kind of immobiliser it has, the standard sigma one has two circuits, one is obviously for the starter motor as it won't turn over with it activated, not sure if the second is on the fuel pump or ignition live. In the old days they were nothing more than a relay which were notoriously unreliable, I'd like to think the more modern ones are solid state so there is no wearing out or dirty contacts. Is there a cam sensor that sits near the turbo that could be getting hot and starting to break down, just a thought as I'm really no expert on these things? Must be worth going round all the connector plugs on any engine wiring and giving them a clean.
