Their website says AC (on any car not just Volvo) can lose up to 15% coolant per annum, whether that's true or simply something to encourage business I really don't know.

No it is not possible that the factory did not put enough in , the factory AC filling machines sent the exact amount of gas used to the cars build sheet file which is viewable at every dealer . I'm sure the dealer would have done it at no cost goodwill so soon out of warranty . My local dealer wouldn't, a complete waste of space, hence why it's serviced by one some distance away. 60 mile round trip on the off chance of goodwill or £69 for a home visit, hmmm let me think?
I guess you will know if you have a leak in 2022 !

Someone might but it won't be me as it roughly coincides with the next D4 major engine rebuild being due for the gunge build up which I'm fairly sure Volvo won't pick up the tab for next time around.
