Thanks Joe, I had to replace the gear shift console. I put the car on the diagnostics and it found four faults regards gear shift unit apparently Jaguar knew there was a fault with them after production and recalled the faulty units back to main dealers. As for me I'm out of pocket by the tune of £491.25 plus VAT for the unit. Bit of a fiddly job as I had to remove most of the WHOLE console lol, but all done now and working fine. Thanks again Joe.
