Hello......as of late, I've been having an issue everytime I go to add gas in my XE. It does not want to start immediately, but after about 5 minutes of multiple tried, it will finally turn-over. The warning light states "Tighten Gas Cap". I've had a leak test (Jaguar Service) and it passed. I am assuming that it is my Purge Valve staying closed after refueling, Does anyone know where the location is. A picture would be greatful. Thank you in advance.

 

Going to need more information. What kind of engine? Any codes?

 

Thank you for the response. Yes, the Code is P0442 and I have a turbocharged Petrol 2.0 Liter engine.
