Actually joined the group for a mechanic friend in the Northwest of England - no access to a computer, or desire to learn to use one - who is having major problems with his 1999 Volkswagon T-4 Caravelle - 8 seater mini-van. He's convinced that the reason the van will not stay running is the immobilizer. It will run on brake fluid. He is a qualified motor mechanic but is not conversant in the electronics. Any ideas???
