Hey folks, need some advice here..
Few month ago I noticed that my car starts to vibrate every time the car drives at the 6th gear, somewhere between 80 and 100 Km/h, dealer investigated and after several fixes (trans oil change, programming, etc...) recommended replacing the gear box under the extended warranty which I accepted.
Now I got a call from them saying that they have replaced the gear box but they are still noticing a body vibration while driving around 80 Km/h, which is exactly why I took it there the first time. Dealer is now requesting to replace the engine mountings stating this is required to fix the issue but this doesn't make much sense to me since there is almost no vibration while driving at other gears.
Need your advice here if anyone has seen a similar issue and whether I should accept replacing the engine mountings which wont be covered by the warranty..

Wasn’t there a TSB about engine mounts on the X260.
The engine mounts and exhaust vibration dampers seem to be common topics for vibrations.

I recon the engine mounts might need replacement but still few miles in them. Car has only 40k so far… thought find it strange since these would normally cause vibration at idle and not while driving at a specific gear and not the others…

 

[MrKis]

Are they electronically controlled mounts?

Are they electronically controlled mounts?

have no idea, how do I find out?

 

[MrKis]

Are there wires going into them.
Or a vacuum line?


Doesn’t make much difference really. Might explain why it behaves weirdly.

car is with the dealer so cannot check.. so should I accept this replacement or is it a trial and error procedure they are following?

 

[MrKis]

I would. New mounts are nice to have given there have been issues with them. As long as it solves the issue your good.
However, if the issue is not resolved I wouldn’t be paying for them.
Request that they road test the car afterwards for the vibration and then do the same yourself before you pay for it.

thank you all for the comments, replacing the mounts solved the issue.

Hii Man did you figure out the problem yet? Cause I have the same problem here with my 2018 XF S V6

Did you see this.

[mohameddawoud87]

Did you see this.

Yeah just saw it now. I have exactly the same thing vibration at 80 - 100 km at only the 6th gear. So should I ask to replace the transmission as well?

 

[MrKis]

I wouldn’t. The gearboxes are very robust.
Your issue could lie with tyres, wheels engine mounts or exhaust vibration dampers.
I guess it could be the prop shaft too.

If your symptoms go away when a lower gear is selected, you can rule out a lot of those things.

Neither time from the seems of it..
