Handling on bends
Hi guys ,
Increasingly over the past few weeks there’s a problem occurring when I drive into bends to hard or go round roundabouts to fast , the vehicle kind locks up and makes a funny groaning noise and the yellow triangle inside the circle warning light on the dash starts flashing ( traction control I think )
Anyone got any ideas to steer me in the right direction to investigate ?

DSC is kicking in ...options are, you are a maniac, tyre pressures low or a suspension related issue.21 year LR veteran > D2 GS 2003 > D3 S 2006 > D3 HSE 2009 > D4 HSE 2013 > D4 HSE 2015 > D5 HSE 2018 > DS HSE R-Dynamic P300e 2021

Incorrect Steering angle calibration will also give these symptoms, can come loose .

Lol possibly maniac
But at the start the problem occurred when driving into bends hard now it happens at just normal speed going round roundabouts

I had this in Switzerland driving on RH side of road , turned out to be worn rear suspension bushes. Turned DSC off on twisty sections until I got home. Also had same problem another time when steering angle sensor came loose.
Does it happen on both LH and RH bends or just one hand?

Errr that’s a good question, not entirely sure, both I think 🤔
What would be the significance if it was just on one side ?
Where is the steering angle sensor located ?
Start with tyres, are they at the correct pressure, decent amount of tread & even wear.
Then all of the above need checking in sequence.

Interestingly I've only ever had this happen once (for the benefit of the poster above who it seems is also from Herefordshire, it was on the road between Monmouth and Chepstow). There is a particularly long and fairly tight bend, but not tight enough that you can't take it at about 30 or 40mph. Anyway, on the outward journey a few weeks back a little triangle light flashed up for a split second as I was going round it and the car rolled.
A few hours later heading home on the exact same bend the car rolled and the light came on, followed by a bong and a message saying suspension de-activated, or normal mode only or something. Stayed on for about the next 5 miles until I pulled in and got lunch. After lunch it was gone out and it's not been on in the subsequent 3 or 4 hundred miles since. So I am assuming it's just down to me driving like a maniac around that one bend as somebody mentioned. (I have since driven the bend a few times, much more slowly, and it's been fine!).Discovery 3 XS - sold

What NJSS said. Jut had 4 new tires fitted and the difference is incredible even though 2 of the old tires were only worn on the outside shoulder.
The car used to pitch and bounce, even on slow corners if they were tight, and the handling was very vague, as if the tires were severely under inflated. It drove like this even after I'd checked and topped pressures up as necessary.
My wheel alignments were also poor, particularly camber, but it's the front and rear toe that wear the tires mostly. Since it's all been corrected the car feels planted and the steering much more direct. Because these things deteriorate gradually we get used to them and only realise the extent of the problems after they've been fixed.VR6 > 330D Touring > D3 HSE > !?XC90?!

I had this with mine after having the tracking done. It turned out that wheels straight ahead showed on the computer as 16 degrees, interestingly it only happened on specific bends that were fairly gentle so it must have been the perfect setting to really upset the systems. All sorted by having the steering angle sensor calibrated. It's very disconcerting.

Further to the above it also seems to have been the cause of my occasional warning chime followed by 'special programmes off' then 'HDC unavailable' and finally suspension lowered which I got in and out whilst driving on long A30 runs. This hasn't happened since the calibration so (fingers crossed' it was connected.

+1
Especially the upper rear arm "rear" bush. If this is shot the car will roll heavily onto the offending side!yµ (idµ - eAµ) ψ=mψ

Update
Ok bit of an update and additional questions/ advice needed -
It appears my DSC problem was accentuated by a slow puncture/ soft wheel but I believe there is still an underlying problem there apart from a soft wheel as the DSC still kicks in slightly on bad bends ( only on RH bends ) .
While driving the disco it doesn’t feel anchored to the road , there seems to be a slight swaying side to side and the body seems to bob side to side , ever so slightly, you only realize it’s so bad when you get into another vehicle and drive it to notice the difference.
So I’m thinking it’s either the bushes ( all round ) - the wheel bearings - or the shocks .
How do I check all of the above ????
