Squirm on high speed bends?

Trying to determine whether it is a trait of the car or something wrong with mine.....
Overall the handling of my L494 is incredible and defies a car of its size...however a couple of times it has behaved in a slightly disconcerting but very subtle way...on a long bend, such as a long motorway access ramp and when pushing on the car gives a little squirm or shimmy mid bend as if it's got active steering ....... This is in normal setting and not in Dynamic mode...

Anyone else had it? It is almost like a worn bush feeling that alters the track during a long radius bend....why it's disconcerting is it almost feels if the car is momentarily losing traction on the rear end...like hitting a wet drain cover... But nowhere near as dramatic as that.....

Thoughts on a postcode? Car is a 64 plate with 20000 miles...

I have noticed this on motorway exits, it only happen in normal mode, when in dynamic mode on the same exit, I can go faster without any issue, so I assume it must be car taking action to reduce the body roll and keep it stable. According to LR Experience Instructor, active roll bars provide small amount to body roll prevention even in normal mode, maybe its only when car has rolled beyond a certain amount that it kicks in unlike the dynamic mode where its works full time.

Could it be a side effect of the "torque vectoring" that L494 has? I Haven't noticed in either my RRS2 or in the Evqoue with which also had Torque vectoring, but maybe I am not driving it fast enough on sweeping slip road bends........... 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

of course you could just leave it in dynamic mode - makes the bends better, and use your flappy paddle if it doesn't shift to 8th for cruising..... just saying... Whistle

If you go in Sport Dynamic on nice bit of B road, you can really feel it doing it's stuff, but then circa 6200 rpm in third is PDQ! 5.0 Ltr Superchrged RRS2, Chile Red, Sideways out of junctions!
TDV8 HST Stornaway on a 08.. remapped.. now gone and replaced, was a mighty fine car..

You're all bad men! ..... I think udash is probably right..it feels like something is altering and probably firming the settings up...
But in doing so it alters your line slightly!
I love Dynamic mode but it's also quite hard which is brilliant when you want to push on but for cruising to the office it's a bit hard core!

I'm glad someone else has experienced this problem!i thought it was me going mad! Thanks for your thoughts....

Interesting, and causes a question from myself:

I can discern no difference in ride "firmness" between "auto" and "dynamic" whatsoever, although I do notice other subtle changes.

Wonder if the 20" wheels on my car are smothering any change in ride stiffness?

Or is "dynamic" just not working? MY2016 HSE D SDV6 - gone due to fuel dilution problems.

There is a definite hardening of the suspension, the steering firms up and the responses are crisper.....should be quite noticeable....

i find use of dynamic over normal quite a difference - and actually unlike some tend to be in this mode most of the time, as the body roll is significantly reduced - i tend to then flit between sport / non sport on the gearbox as takes my fancy and depending on what i am doing.

i am though running on 22" wheels

I tend to find switching everything off has the same effect 😄🏁 but then I am on a test track when I do....

I had 2 moments which can be described like yours. Both in a long sweeping bend, driving fast but not "on the edge" (around 70 mph and both bends were slightly downhill)

Good....that's not just me then...exactly the same not pressing on to much and between 60-70 on a long flowing left handed bend both times... It's not dramatic and a tiny squirm but just enough that your reactions are ready to kick in...

At first I thought it was loose wheel nuts and either the wheel moving on the hub or play in a bush which suddenly takes up...

..I had an old 928 many years ago and it did it the same ..I think they called it active steering and it was just a mechanical linkage under load....
