Deactivate immobilizer or code new ignition key for VW Caddy

Hi CDDHH, it's not recommended to disable the immobilizer as it's a crucial security feature of your vehicle. Coding a new ignition key should be done by a professional to ensure it's done correctly. However, if your vehicle starts and then goes off again, it might not be an issue with the key or immobilizer. It could be a fuel delivery issue, a problem with the ignition system, or even a faulty sensor. I would suggest starting with checking the fuel pump and the spark plugs. If you're not comfortable doing this, I'd recommend taking your vehicle to a professional mechanic. Please let us know how it goes.
