I am exactly what you describe, a true Land Rover enthusiast, I have three Discos, 2 disco1s and 1 Disco 2, they all need work and I don't have the money to do them up, so two of them are SORNed waiting until I have the time and space to do it all myself while I keep my daily driver on the road. My remark was tongue in cheek and you know as well as I do that really we would rather see you stop suffering. Which is why we offer advice and nudges in the right direction all the time. I agree, it is unlikely to be a BCU issue. If it was, I doubt the vehicle would be driveable, but Sierrafery et al, would know more about it than me. Don't lose your sense of humour.
