Re: 2006 3 litre crd Grand Cherokee
That does seem unusually high if you are not towing or driving in hot weather. A stuck open egr valve could cause high temperatures but i would expect some other error code. Have you checked it over with an obd2 code reader? The dealer diagnostic computer would be needed to read the egr.
