Sorry to resurrect an old thread, but I'm wondering about this recalibration thing.

GraemeS, what were your symptoms and did recalibrating them solve it? Mine seems to roll more than I would expect (to the point where my wife gets travel sick) and cornering at speed is uncomfortable and not very confidence inspiring. I'm sure my P38 was much better in this respect which is a bit surprising. Does this sound damper related?

I get the impression that the problem is more at the rear than the front if that makes any sense. If they were a sensible price I'd be tempted to just replace them, but I'm wondering if it might be worth looking at this route. 2010 4.4 TDV8 Vogue SE

Mine no longer felt tight, tending to not absorb smaller bumps and generally rolling about more than it used to. I followed the suggestion on a Jag forum to switch DSC off to stiffen the shocks and found that the ride firmed-up considerably, indicating that there was more life in the shocks and therefore worth recalibrating. Be aware though that once recalibrated, there is no easy way to reset to the factory defaults which would be required when fitting new shocks although a recalibration with the new shocks on the same surface should produce the previous ride, but probably a better overall ride due to the shocks not worn at all. I tried a few different stretches of rural roads near me, usually with the resultant ride too firm so kept trying slightly better sections. I have yet to discover if reloading the software will also reload the default values but would have to get a fresh copy from GAP to try it. I sometimes feel that mine might not be as good as when new but they're much better than they had been and certainly don't warrant the cost of replacements yet. My big heavy tyres can wreak havoc with the shocks when they've collected mud, putting them out of balance.

The Jag forum thread was in regard to fitting a single new shock that was very stiff initially, but reportedly softened over a number of weeks while DSC was switched off on every drive. The thought was that driving with DSC off caused recalibration gradually but I can neither support nor contradict that thought. I tried driving for a few days with DSC off but the shocks didn't feel any different by the end.

Thanks for that. Not entirely sure they're the same symptoms, but will try the DSC trick to see if that makes any difference.

I have 21 inch wheels which seem to transmit up every bump in the road but the rest of the suspension seems to be so soft that I seem to have the worst of both worlds!

I think I'll hold off on the recalibration though - thanks for the very informative response! 2010 4.4 TDV8 Vogue SE

Well that's interesting. I've been running it with the DSC off for a few days and it's transformed it! The suspension is just how I would expect it to be, the throttle response is better. In fact everything is better (except perhaps for the brakes, which seem less effective).

So, where does this leave me? I don't really want to leave it in DSC off mode indefinitely.

I can't quite work out how the adaptive dynamics operates. It's as if it wants to set all of my settings to jelly mode. From what GraemeS said, I don't really want to go down the recalibration route, but it's tempting if it could improve the ride as much as switching DSC mode off has (although that won't sort the throttle response out). 2010 4.4 TDV8 Vogue SE

I haven't noticed any change in throttle response with DSC off but apart from power reduction when loss of traction occurs, I hadn't expected any change.

Note that enabling cruise control will switch DSC on and that DSC cannot be switched off if CC is already enabled.
