Bring to a reliable workshop and have the mech check it out asap. As long as you top it up regularly it should be safe.

But I suspect somewhere is leaking. Had the same problem twice.

Mine is a 2011 523i. Today sent to munichauto for servicing asked for them to check as coolant kept having to top up. Apparently they claim coolant leaking at radiator. As under warranty they will be changing the parts for me. Didn't ask what they changing.

What type of coolant is best fit for the 6 inline f10 523i ?
