So a couple of months ago my coolant thermostat got stuck open (diagnosed at auto zone) the attendant said that I can’t drive it at all until I get it fixed but my mechanic (not bmw mechanic) said it isn’t a problem, I’m skeptical because my mechanic has messed up a previous car I asked him to work on because he didn’t know how to work on it (it was a Nissan and he works for Mazda)
