Attached is a link to a You Tube video I think you might find interesting. (There is a photo of the Grand Cherokee, but I think it is the 2.5l Cherokee.)



I love how the Jeep stealership wanted to replace the engine!



It just shows how hard it is to diagnose problems with these CRDs.



There are other videos on this channel which you might also find interesting.
