Here's the link on the fix to the immobiliser. Read WillPassat's post. I fixed mine by taking the upper shroud behind the steering wheel off and tucked the wire and its plastic casing running from the airbag to the instrument cluster area behind the shroud. Never had any problems since.

If your immobiliser light (orange light with car and key symbol) is not going out your car will never be able to start. If it goes out then replace the camsensor then crank sensor (not that its worked for me!)
