I saw a Carwow review (iirc) where the charging speed at a rapid charger was slower than expected but the reviewer later clarified that it was due to the battery not being pre-conditioned for optimal charging.
Is this correct and if so how is the preconditioning activated?
If it is accurate, I could understand if it was automated from selecting a charger from Mercedes Me / navigation services, but for ad hoc charging or charging where the location isn’t supported by MBUX is there a manual way to activate it? (If indeed it is ‘a thing’)

No manual way on any EV.
Evens so, you must drive a lot (with the charging location marked as destination/waypoint in MBUX navi) in order to have the time to precondition the battery.
