Hi, I am new to these forums...Love your enthuseasm about the Lovely, Beautiful, XF (I feel tyhe same). I have previously owned from new, 3 X Types, a 2.0L Petrol, a 2.5L- AWD Petrol (what a Road Hugger) and lastly a 2.2L Diesel "Sovereign". Unfortunately, I am finding my XF very "Harsh Riding" after my "Sovereign. I can understand that the suspention needs to be "Harder" on my XF but when I traverse some undulating roads at low speeds, the XF bounces about so much so that it becomes very, very uncomfortable as I get thrown violently from side to side in my very comforatable seat. When I had a test drive in a 3.0L D XF and I did not notice any of this unwanted action at the time. I also experience a sort of "Wallowing" feeling on some main roads. I have contacted Jaguar Head Office, who state that this should not be happening and the result is that my XF is going back to the dealers next week for inspection. Is there any chance that you have come across this problem with your XF.....Happy Motoring in your Lovely XF......BillyBoy
