All done. It wasn't battery related. It wasn't gear control related. Let down by multiple independent mechanics who claimed to have Jaguar training. Issue was wiring to comms module broken due to water coming in! Very happy with Jaguar dealership servicing for identifying and repairing. Obviously expensive.
Well, it's definitely not battery related. Had new one fitted and all issues remain. So got original battery refitted. Mechanic !Removed! off.
Car totally stuck. Will need lifting onto truck I guess and delivered to Jaguar.
Thx again. Please excuse my rampant stupidity, but do you have an idiots guide on how to charge the battery. I am clearly non technical. Can it be charged in situ or has to be removed. Apologies
