A couple of months ago my Jag ( 20 mod. XE Dynamic S ) started to get a progressive worse vibration noise from my exhaust, got the car put up on the ramps ( at my local tyre dealer ) and found it to be a rubber bush with a steel liner on a setup of two pins at horizontal opposites ( not connected to anything ) that were welded on at the front of the back box. I duly took the car to the local Jag dealer and they fitted a new rubber bush ( only necessary on the one side, on driving it home the car was vibrating a bit so I called the dealer and said the vibration was worse, I was told to bring it back in ( 3 weeks between appointments ), they reset the exhaust system hangers but again on driving home the vibration was still there, this time they collected my car and gave me a loan car (delivered to my house as I was fed up driving the 18 odd miles to them ), they said they would contact the factory for advice, the advice they got was to remove the ( dampeners ?) completely as new one's were not now fitted to new Xe models. I got it back after 4 days then a couple of weeks later I got a call from the dealer to see if I was happy with the repair, I replied that there was an occasional ripple vibration that went through the car but being fed up with all bother I would just live with it.

 

I have the same problem since we bought our xe. Thought is a bush gone, but looking at the engine revs, it keeps around 720rpm, when engine cold in the morning keeps 850rpm and does not have the vibration on the exhaust. 
Think my engine revs are quite low, surely should be around 8-900?

What is everyone else's jag xe 2.0 engine revs once its warmed up?

I still get vibration when the engine is when Idling after a hot run, the rev counter is showing 700rpm.which sounds a bit low for a diesel, I will follow that up with the Dealer after the festivities are over, my mileage is just over 8000, the car is 22months old and the engine could just be freeing itself off.
