....if your QP has skyhook, you will also need error cancelling units as the skyhook system will expect signals back from the skyhook CANBUS connections....
Indeed.Yes the 'plug-in error message cancellation kit' is £375 from these guys. Presumably this is some electronics that tells the system that there is Skyhook 'really' and it is responding to commands.

I had tramlining for months and the dealer could not solve it. Indeed it turned out to be tyres - went away when I switched all four to Pirelli PZ4s. It can be surprising that even though the tramlining can feel like it’s happening from the rear, can start from the behaviour of the fronts. Assuming basic play issues have been ruled out, tyres may well be the issue.I'm not an expert or a performance driver really, but my issue is that Skyhook seems to be too soft and wallowy in 'Normal', and too firm and crashy in 'Sport'. I think I preferred my previous non Skyhook QPV. Also, I would like to cure the rear tramlining if possible, but that may be more of a tyre choice issue.

It was at its worst on my previous QPV with Pirelli PZeros! I wish I understood this stuff better...
Mine tramlined and skipped about on Pirelli. They are just s**t.Firstly mechanical play should be ruled out. For example in the bearings and tie rods. Or worn out bushings. It can also be related to wheel geometry.
If it’s not mechanical, for tramlining it’s not so much the brand per se, but more related to the age, deterioration, stiffness of the rubber in the tyres - with less give, the tyre will transmit tramlines directly to your vehicle. Our cars are high performance beasts with low tolerances. Out of interest, what are the ages of your tyres? You should have a 4 digit number indicating the year and week of manufacture e.g. 2201 would mean it was made in the first week of 2022.
Both statements may be true but not related.Mine tramlined and skipped about on Pirelli. They are just s**t.
There is a very good description here:So how does Skyhook work? Is it as simple as two settings within the shock controlling the size of a hole though which oil can flow? Large hole is soft, small hole is harder? And is it the springs or the shocks that determine the ride. Ie could you just get stiffer springs and keep the shocks?

That is hideousSounds like you need to sell up and buy a Citroen Mark. Hydraulic cushion suspension for those who don't like the sport button.

Well it's that or put a cushion on the seat. I will take the hard ride option thanks.That is hideous
