Did completed re-calibration today. So here long feedback comes.
It was required because packed totally new OEM DCC set (shock absorbers, coil springs, repair mounting kit, anti roll bar links and bushes) that becuase fabric ones dead with oil blow after c.a. 150000km.... recommend using comfort mode moderately or not at high speed to avoid drastic drops... Is what mechanic said🤷♂️
Also found interesting thing, the % values in Adaptation: Adapting with deflected wheels, are stored fixed, logic not(?))), but how Understood that, was to measure them 4 time, with and without adapted - while leveled up and standing. (Attached pics)
That values are stored as base, which will reflect on power delivery adjustment when changing different DCC modes, this can be checked while running live test with sensors and drive.
Seems like rear right use default values making others reflect on it, maybe because fuel tank position, that sensor also shows available while others not possible in live data info, and it will not change after recalibration, or different way stored or somthing still to learn.
So, after adaptation, already made couple hundred km on highway, as well urban routes, same day)))..
There is difference YES even with OEM new pack, but many people saying/thinking see no issue no need to, so it's a big big miss if use low spring and not recalibrate !!!
As you can see on pics small % diferences but it results in more clearance and soft Comfort mode, while Normal mode has much predictions mean becomes ideal option, for the Sport gained even more hardness controll.
After discussion with dealer, they communicated that DCC calibration must be completed after any suspension works, and no way to use it without because reflects on wheel alignment (front / rear), ACC and lights too, all together to be adjusted, not cheap at all, but then you get the right feeling.
The DCC recalibration may be required twice, because when aligning steering/wheels the arms will push a bit the whole construction at least on rear side, so it's a complex procedure of couple hours, then having wheel aligned and DCC calibrated, it's time to proceed with beam lights and ACC adjustment.
Good if found a shop with all tools, else run across city, usually only dealer will have all this at one place.
