Silly question but is the solenoid plugged into the electrical system? Also check a patch lead hasn't been used by the factory (to extend a shorter, common loom so it reaches the position of the VVT solenoid on your engine) and wasn't disconnected by the people that did the timing chain work. Also try resetting the codes, it may have been the garage forgot to reconnect when they did the timing chains and because the fault code didn't show immediately, didn't clear it - a historical fault can sometimes show later and cause problems.

The original fit on your X Type would have been Pirelli P6000J - the J denoting Jaguar. Sadly these are no longer available, i've used P6000s (the generic P6000 rather than the "J" type) on other cars and they've been really good tyres. I have a pair of (10 year old) P6000s on the front of my S Type and because of their age, their grip is reduced. On the rear are (5 year old) P7 Cinturatos, not impressed with those either! I'm looking for a set of tyres to replace all 4 on mine but with yours being AWD, you'll have to renew all 4 at the same time with the same type all round to get optimum results. There used to be a brand known as Corsa, these were old-pattern Pirelli tyres, made by Pirelli, i put a set of these on an old Volvo 740 about 18 years ago and transformed the car. I know with Jaguars in general, having the same type of tyre all round is more important than other cars but with any AWD/4WD it's also important to have them all wearing at the same rate to avoid transmission wind-up. I'm currently looking at a set of : https://www.ebay.co.uk/itm/144518219295 for mine, surprisingly good reviews for a "budget" tyre and not being impressed with the Pirellis (first time ever Pirelli have failed to impress me) they're probably a reasonable bet. Will be interested to know what you finally decide on. 😉 😄
