Twice in a month my CEL has illuminated for no apparent reason.

Also, the demonstrator I test drove last Spring also had the CEL illuminated.

That would mean Jaguar has had a year to find the fault without success.

Also, after shutting off the engine I heard a faint whine or buzzing noise from the gas tank area which stopped shortly after I opened the gas cap.


Car runs fine at least.

Same issue as before, no fault could be found. The fault occurs only around my local town according to Jaguar. Gasoline formulation is suspected to be involved.

computer. I believe certain faults are retained by the OBDII memory only for a particular length of time and then the CEL goes out if the fault does not recur.

Is anybody reading this board anymore? Is everyone totally happy with their XF or just sold them right away?
