i would say yes go to store, but i probably would get owned by everyone on these forums.* so go to the dealer pay the extra 5 bucks and get some coolant for you bmw

just b/c it came from a european mechanic shop doesn't mean they would put BMW coolant. I go to a european mechanic as well (obviously since it is a bmw) when i have certain problems when tools are not at hand and they dont even use BMW coolant. Trust me, just flush it out and use bmw coolant. I had my coolant flushed out 6 months ago and when i found out they put some green crap coolant in my car i flushed it out myself and put bmw coolant. you dont want phosphate deposits lurking in your engine.

thermodynamically increase in coolant temperature increases coolant pressure... Coolant flow is driven by pump... so coolant temperature and pressure must fit the pump requirement...
Basically we can't judge how good or bad is the refrigerant, one good way to see its performance whether it suits ur car is by running ur engine and observe the temperature raise behaviour. If ur car'e temp reading shows rapid increment when u start ur engine, u gotta watch out... then if thing seems normal, simply run ur car for few hours in ur spare time and observe again...
Some may say the coolant may damage ur pump, that's right if u put freak crazy wrong coolant (in this case i would rather say refrigerant)... For example, if u change ur coolant with comercial air cond refrigerant, u may damage ur pump... like u pump up swamp using water pump... but in ur case, u say u go to one proper autoservice, i believe u r OK.
One good news for u, coolant is not simply used as a engine heat exchanger, the same flow is also used in ur car's air cond system... normally car has about the same air cond output let`s say 20degrees C then the vehicles' manufacture may use about the same pump and coolant... slight different does not matter... like u pump up coconut juice with water pump =) see wat i mean?
U dun have to go to BMW house for every single problem... like when u change ur oil, u can use Shell, BP, Caltex, etc...slight different makes no big deal... (you are not performance racer) =)
