Fumes coming from filler cap

Recommended Posts

Has anyone else noticed this. Just recently I’ve noticed blue(ish) coloured fumes coming out of the diesel filler cap when I go to fill up. I wouldn’t think that there is a problem but I’ve had diesels for the last 15 years and never noticed it until I bought my XF. Any comments greatly appreciated.

Update, it only happens when I’m putting diesel into the tank

Mine does this too although only picked the car up yesterday so can’t say if it’s repeatable issue...
