Go this yellow triangle warning today. Opened the cap and made sure it's tightenedbut itstill displays on the dash. Anyone get this warning before? Bad Cap? Just curious before I bring it in on Monday. TIA!

 

Likely your dmtl pump is not sealing. If your dealer is any good they will run evap self test watch it fail then clamp off hose to pump. It will then pass. They should then replace the dmtl pump and canister assembley.

 

Thanks; I am thinking the DTML pump the techs replaced needs to be replaced again or repair a hose....?
I will definitely follow-up.... Thank you again for your reply.

 

11yr old thread - now that's resurrection!

 

............... and the OP has a 2009 XF Supercharged so it's also transmutation.

Mine was the cap about 2 years ago.
