I stand corrected.
Here's one thread on hard ride I recall reading some time back: https://www.disco3.co.uk/forum/hard-ride-110686.html2016 Skoda Octavia VRS Estate

Re: Seriously hard ride

Over the past year I have replaced all the suspension components on the car apart from the ride height sensors and the cross link valves, the car goes up and down ok no fault codes but it’s like being in acces over every bump or crack in the road I have also just replaced all the tyres, all pressures are correct it’s driving me mad, I’m considering lifting the car, using the iid to vent all the air then making sure the centre of the guns are at the correct height undoing and re tightening all the nuts holding the arms on as the suspension is so hard, does anyone have any ideas before I proceed
Hi
Hope this doesn’t sound daft , what is ur suspensions pressure plse
Here’s also a chart
What size 19 tyres did u fit plse and what pressure did u pump them up to , have u tried letting them down a little to see if it makes any difference
Max pressure 1782 then when exhaust vents it’s 277 but that’s only in the compressor i think, if I press off road height the compressor kicks in at around 1480 it raises to off road in about 10 seconds then the pressure raises to 1782 in a few mins not sure how quick this should be.
Tyres are standard HSE fitment 255-55-19 33psi front 36psi back, I’ve changed the pressure and it’s still like I’ve got sport car springs if I hit a pot hole or a rough surfaceRange Rover Westminster 4.4 TDV8 what a car

Hi
Nothing obvious there then
I replaced my front struts with Dunlop’s and been really happy with them
Trying to think of what could be causing the ride quality and indeed must be frustrating
Suppose the only thing I can think of is the bushings , if there RRS ones
Know when I done mine I replaced all my drop links but that’s of course just to deal with the cornering
Wonder if it’s worth undoing the wishbone bolts and rechecking the heights ?????
Know when I installed my wishbones I didn’t realise at first the white bits of plastic that where on the bushes were the bump stops , are they in the right position ???
Assume the ride quality was bad before u fitted the new tyres
Know that’s not much help to u
Plse let us know if u make any progress and hopefully someone will have the answer
PS, are all the pipes in the correct position on the valve blocks ??
Have u tried disabling the DSC and seeing what it’s like , just generally thinking
All arms and drop links from AF were D3 ones not RRS I’ll give disabling DSC a go but I think undoing and re doing the bolts will at least rule those out, I may even mess with tyre pressures one thing I did notice was if the car is fully loaded it’s much better over the rough roads which is oddRange Rover Westminster 4.4 TDV8 what a car

That almost sounds like its oversprung, ie springs to hard for their job, which is what you got in the old days of leaf springs, the vehicle was specced for loaded condition and when it was empty it was a terrible bouncy ride.
Question, did it ride bad before the new arms?

Hi
At least u know it’s quality parts that you’ve fitted
Indeed see what happens if u undo the wishbones set the height and do them back up again
Believe when the DSC is disabled it makes the suspension act the same way as a live beam axle would, by opening the valve blocks to allow air to go from one to another
Assume it was the same before u fitted the new tyres
