Have just checked the climate sync.... on start up this morning, nope, its forgotten about it.
It also forgot the "air care" setting I had enabled the other week.
On my Mk7.5 these settings were persistent, whether or not by design they should be on a Mk8.... I don't know.
The user manual is utterly crap, hardly telling you anything at all - suspect that is deliberate now everything is in software...
