Yes, tyres seem to be one area where there is some variation as well. I did try 255/60s, they were a bit more compliant but a bit squirmy under braking when compared to the 50s I have now.

Careful running lower pressure as it will cause uneven and premature wear at the tread edges. I had this inadvertently as my tyre inflator was reading 2-3psi over the actual pressure. I now run 37psi all round and it’s not harsh (225/55 R20 Verde). 2012 TDV8 Vogue (L322) |

I think if this thread sticks to the “can it be switchable” part of the query, not saying it should… but not sure how any external influence switch or feed might affect DSC etc, as I thought they sort of worked together? Maybe you can treat it as separate systems and feed into the 3 specific wires from each shocker for the dynamics and leave the height feeds as is, as there are 6 wires on the L322. Might be harder on a 405 as those have both systems combined on the 3 wires. That said, there are also accelerometers etc. My M5’s had switchable settings and you could tell the difference.

My Audi had selectable settings for sport and comfort as well as auto. One thing I forgot to mention was mine did improve when I changed a failed front height sensor. Once removed the pivot was very stiff which I assumed had been that way for some time before the electrical part failed. A sticky action or a loose pivot would send erratic signals to the ECU possibly making its control less than optimal. Maybe worth going round each one and detaching the mount to the moving suspension arm and checking for both stickiness and any looseness? 2012 TDV8 Vogue (L322) |

My understanding is that the adaptive dampers are by default in their stiffest setting, and that to soften them, the ECU applies current to the damper ... vary the current, vary the damping. You can see it in this vid I made ...

Contrary to what others have reported, I used the Gap tool to set the CVDs to calibration mode which persists for approximately 30 seconds IIRC to adjust the ride to my liking once the shocks lost their ability to control the vehicle adequately. Setting calibration mode whilst stationary made the ride very harsh (I didn't reaslise that the vehicle should be moving) and setting calibration mode whilst traversing a very rough track (my farm driveway) made the ride very soft and unable to provide adequate control over some bumps. I eventually found that travelling at 80kph on a particular section of a local sealed yet uneven secondary road created the best ride for me.

I tried recalibration last week but didn't notice any difference but the ride was not harsh at the time so maybe worth trying again if I notice it deteriorating. The CVD calibration is one data set that the GAP tool records for later recovery so it may well be important? 2012 TDV8 Vogue (L322) |

Tried another calibration today. The procedure only lasts 10 seconds so not sure what it can actually learn in that time. 2012 TDV8 Vogue (L322) |

I'll give that a go, have to get out of town in the morning for a less than smooth road to set it off though, will se what happens.

I recalibrated it this morning out on a country road about 50mph as the city streets are smooth exepting a few speedbumps.
