Without knowing too much about the car itself my buddy had a bmw 3 series from 10'or 11' and his cooling fin had a chip in it(not likely due to leaks). The gaskets on bmws from what I know are known to have a "hairline" break to them. Notoriously on any bmw I've ever seen or looked at, the block itself has been pretty solid so I'd be leaning more towards the gasket with what information has been provided
Do you know all the tips on getting home with an overheating car?
Also if you like German cars Audi is the way to go(my personal opinion), haven't had anything other then scheduled maintenance on my car and knock on wood no problems
Sorry for any mistypes I'm on my phone
