Well I am getting a little hacked off with my XF Since buying it from Jaguar Tamworth I have no end of issues with the navigation, a/c, control centre. This culminated with several visits to the garage, module changes and what I though was finally the changing of parking sensors. I was led into a false sense of " it all behind me now" not so..... The ?,?!.!,,,ing key fob now randomly unlocks the car, how crap is it that you lock the car and reluctantly walk off knowing that before you take 10 pace the car unlocks to the sound of the opening wing mirrors Ahrgggg. it teases me.. I am using the spare fob but has anyone experienced this before? Is the fob in need of reprogramming or binning, like I feel about the car right now? Any advise or experiences would be welcome. thanks in advance
