Odd Random significant vibrations at high speed

My wife's RR L405 Supercharged (63 plate) has suddenly started to vibrate randomly.

The first occasion on the M11 I assumed it was a road surface issue but eventually pulled over to the hard shoulder and after checking tyres okay I pulled away and it had gone.

It's now happened twice more on the M40, second time it happened I had to pull over twice as the first time it didn't solve the problem.

It's been to two garages from the warranty company and neither really have any idea.

They say can't be wheel balance or prop as it would happen all the time.

It normally happens when travelling at about 85mph in the cruise and after about an hour or so but equally you can drive for 2/3 hours and not have anything.

Anyone have any ideas, the car did about 3 months ago pop up with a huge gear box error and lots of warning light but on turning off and restarted they all disappeared.

Thanks

Annoying and very distracting!
In a strong headwind mine can sometimes make a resonant buzzing/vibrating noise from the mid-upper screen area. I've examined all the screen sealing areas, airbox, etc but can't eliminate it. Once I'd figured out what it was, though, i became more relaxed about it.

A few questions about your situation, if I may, to tease out some more details:
Can you detect where the vibration is coming from?
Is the nature of the vibration one that you more feel than hear or vice verse?
If you increase or decrease speed does the vibration change or disappear?
Have you tried changing gear manually to see if the vibration disappears?
Does opening a window or manipulating the ventilator on controls have an effect?
Have you checked or tried varying your tyre pressures? 2006MY 4.2 SC

Have you had the engine mountings checked? I would. It's an expensive repair, hence why Warranty and Dealers are often coy about taking this repair on.

Sorry my answers below, I wasn't notified of any replies on the topic so forgot to check back:

A few questions about your situation, if I may, to tease out some more details:
Can you detect where the vibration is coming from? - No, it's not apparent to me.
Is the nature of the vibration one that you more feel than hear or vice verse? - More hear to start, there isn't huge vibration but once it's vibrating it just carries on and is very noticeable.
If you increase or decrease speed does the vibration change or disappear? - No it won't go away until the car is stationary and then one one occasion it start again as soon as I drove off so I had to stop again.
Have you tried changing gear manually to see if the vibration disappears? - No but will do.
Does opening a window or manipulating the ventilator on controls have an effect? - Don't know will ty.
Have you checked or tried varying your tyre pressures?
- No I haven't, I do have one tyre with a very very slow leak so that one I pump up every couple of months.

The one thing I do also think is new is the car makes creaking noises at low speed when parking which I don't recall it made before.

So just to update anyone who might be interested, I think the vibration was being caused by a failing tyre. That slow leak turned one day into quite a bit leak and we have to pull over and most of the inside tyre wall was torn. Pretty alarming really that this can happen.

Must say the 22" tyres are just a PITA, I've gone through so many of them failing, punctures etc... 1994 Range Rover LSE Autobiography

Had a very similar random vibration on my wife's Audi Q7 at certain speeds. Turned out to be a cracked radial belt in the tire. Nearly impossible to spot with my untrained eye b/c the tire surface looked perfectly normal. Replaced the tire and all was fixed.
