Mines had a problem with the starter!
Only bought it the yesterday, took it from garage around the corner to fill up and it wouldn't start. Phoned the garage and they said it will be the immobiliser, I said I'd tried it a few times and it was the immobiliser.
They sent one guy around who messed about with the key fob and then phoned his mate, he got told it was probably the immobiliser. After another ten mins another two guys came out. They tried exactly the same thing with no luck, tried the battery with a jump starter no luck then one of them got under and tapped the starter whilst someone turned the key and she fired up.
Got home and it was fine for the next two starts then today at work I had to get someone to turn the key whilst I tapped the starter. The garage are taking her back in on monday to replace the starter so that should end that problem....
Fingers crossed, in the mean time I've got a small metal bar with my keys just in case.
