Check Fuel Filler Cap is on?

Hello,
My Check Fuel Filler Gap light is on (2009 XF Supercharged). I had a new DTML pump put on a few weeks back--and I have a new Jaguar Gas Gap--from an authorized Jaguar Dealer, so why would the "gas cap" light come on?

just a guess but recall a gent on the X350 forum who had a gas cap error code. Turned out the cap retainer plastic was preventing the cap from sealing properly. In any event, check the seal.

But also this from the threads below:

Welcome to the forum kenmicn,

I've moved your question from General Tech Help to X250 forum. This is the place to post technical questions about your model.

I had this exact problem with my S-Type. Every year or so the gas cap light would come on. I had my local mechanic take a look but cause was not apparent. So I just decided to replace the cap with an OEM one. That ~$30 brought me peace until it happened again...
