I have some problems with starting my Bentley, but if I turn off the main switch for about an half hour and then turn the power on again. The car is starting without problems, I think is a immobilizer problem but not sure.
On my 98 Azure if you take take the key out you have to lock the car with remote and unlock and then put key in. As long as key stays in yo don't need to do it again. If you have an issue with immobiliser it gives a message 'check gearbox'. did have issues of being spiked by microwave masts or traffic light control in London. Wouldn't engage remote. I ended up sending the Iimmobiliser and remotes to Bowlings and they upgraded it. Plug and play. Perfect.
