my 1999 xj sports had the message come up. it is intermittent.when my jag man read the diagnostics it said coil pack but i was advised that if it became permanent the coil had water in it and not need replacing(about £60 labour included)after a few days ok.

 

Just to save someone else having to tell you this, your post needs to be on the X308 forum?

 

THANK YOU
