Hi, it’s been a while since I was on the forum. I picked up a caddy mk2 van recently and have been trying to sort out an ignition issue... I have searched online/Facebook model groups etc but haven’t found much of an answer.

It starts fine, really nicely in fact. But when you turn the key to the off position it doesn’t stop until I remove the key from the ignition. I have replaced the ignition switch and the problem persists.

Looked at an Elsa win wiring diagram and all wiring seems in order. I am at a loss as to how I should tackle this fault. I have a spare immobiliser coil and key but no barrel unfortunately. The only think I can think is that the barrel has some immobiliser bits inside of it that have stopped working? Can anyone help please? I’d rather not open up my ecu to see if there is any damage as I think the problem is simpler...
