Hello Guys

I am facing two issues with jaguar xf 2013 base model

1. The car starts vibrating when it reaches 100Kph. It also makes an echo sound in the cabin. The mostly vibrations starts from the accelerator and goes to steering wheel. At 100Kph it changes the gear and vibrations frequency get low but doesn’t fade out.

2. I am experiencing jerks at slow speed. For example if I am turning a round abouts or in traffic jams.

if someone can advise me on that it would be great help.

My best guess is either worn out engine mounts and/or cracked/worn giubos (flex discs at each end of the driveshaft).

I'm following this in case one of my symptoms is same.
Its described similar, not 100% same.

I have a strange "feeling" at the start of a full stop. I considered maybe timing or supercharger coupler, but just had both replaced.
I'm "catastrophizing" when I say I fear gears busted in the rear end, but it has a mild grindy sound. When I say feel I mean its there but not really translating to steering wheel or pedals.

Anyway, love to follow the comments responding to the original post'er

Can you post what engine and miles the car has?
We need the most details as possible.
