I've got a 2005 signum 2.0 turbo .
My abs, esp, power steering, engine management, and battery light keeps coming on when driving and the power steering fails. Then it won’t restart for at least 20 goes then starts fine and runs fine. i had a garage read the fault code and it came up as the immobiliser.
Its going back to Vauxhall on tues to hopefully get sorted.
Any ideas what it could be?
