Having watched some other topics on vibration and watched a YouTube video where another forum member had a similar thought I am now thinking engine mounts?

I am becoming very tired of the XE in 3 months of ownership its had:

New battery completely understandable

New starter motor at 21K

and now quite possibly engine mounts.

My weekend car is a Brera S seems more reliable!

Seems unlikely that the engine mounts would only be an issue when on an angle though? Also not sure how common the engine mount issue really is so should be fairly unlikely. From what I’ve seen online the engine mount noise and vibration isn’t subtle at all and would lead to the whole car shaking fairly violently.
Engine mount issue has been fairly common on early cars which this is. The slope could be causing the revs to drop slightly lower than normal. The whole car doesn't shake when the engine mounts go wrong but it normally causes the exhaust or heat shield to vibrate.

It seems the engine mounts are not conventional, in that that are fed / regulated by a vacuum system. I noticed today putting the car in reverse holding it on the brake the rumble occurred albeit it softer than when actually moving. I know it sounds counter intuitive in that it would suggest the gearbox but in a threat about noise I watched a YouTube clip and it was exactly that engine mounting not able to maintain their vacuum.

Does anyone have a guide on how to replace them. My mobile mechanic is self isolating for a month. I have just purchased both sides and am hoping its quite easy. Would also benefit from having the torque settings too.

Thanks

Nick you can get a copy of the workshop manual from this post.............

The job seems a bit large tool orientated ie garage lift equipment

Does look like a big-ish job. OP, do you have a recording of what yours sounds like, or did you get this diagnosed anywhere yet?

Haven't had it diagnosed but listened to similar noises on YouTube recordings and other posts. Only occurs in reverse at the moment or on first start up when coming to a junction. You can just detect it moving from reverse to drive. Had it testing at a high street outlet. They confirmed noise is not driveline related nor steering or suspension.

I have looked at the repair manual guide and am thinking it might be possible to complete but just unbolting each mount at a time and jacking the engine slightly and removing rather than actually moving the mount location on the engine.

If you have a recording you could upload I’ll compare to mine. It doesn’t make a real loud noise but I do feel a slight vibration and have a bit of noise a little after startup, my drive is also sloped.

I am replacing the engine mounts tomorrow and will report back if that has cured it. I do hope so loathe the thought of it going into Jaguar for a diagnosis.

Good luck. If you have time to do a before and after recording I think that will really help others in the future to diagnose the issue.

Great news, I am really starting to consider whether my car has this issue.

I've struggled to find valid examples of the engine mount issue specific to the XE, don't suppose you have links to the examples you used to diagnose yours, or if you know of any sure fire way that I could diagnose the issue.

The car doesn't shake wildly or anything, but it does sound like there's a sort of mild rumble/vibration that starts a few seconds after the car has been started. I don't know much about engine mounts in general, but believe the XE mounts are a form of dynamic mount that adjusts in different situations.

That dynamic nature is making me think that maybe the mounts are an issue on mine, with it seeming to start a couple of seconds after the engine is fired up, which would be when they would probably be moving into whatever the "idle" position is.

Would a video of the engine when the accelerator is quickly pressed (sort of a stabbing of the pedal) be useful for example, would it potentially show excessive movement of the engine when revved?
