Purchased xjr sport new from dealer in April 2017, however gradually became aware of the famous popping from the sunroof. In May 2018 I took it to dealer who following workshop checks, said all was o.k and noise was something detached in spare compartment. Well to say the noise is worse is an understatement. I fell in love with this car and it still makes me smile to look at it but the noise really is annoying and spoiling my Jaguar experience. What is the consensus about the fault, can it ever be truly fixed, is it a design fault, what could or should Jaguar do about it? Your thoughts / advice would be appreciated
