John, that's very helpful thanks. interestingly my 2 issues dating from when I bought my car, appear to have resolved themselves with more regular use! My vehicle had, I think, been standing unused after the death of previous owner, and had had all the usual Jaguar gremlins; new battery fixed a few, but the touchscreen issue and the problems with filling the tank/ frequent cut outs nearly drove me nuts! Did a long trip, requiring multiple tank fills and began to notice the issue was "going away", and now touch wood, have no problem with that. The touchscreen occasionally misbehaves, so on a run where I am not using any functions, I switch it off; instant re birth when I switch on again. Moral of story, like lots of other things Jaguar, give the ECUs time to re set and sort themselves out?
