Hi all. 3 weeks ago, my 2018 750 with 22,000km gave me a low coolant warning. There was no sign of a leak on the garage floor.

I went by the dealer and they topped it up without noting any issues.

I got the same warning again today. Again, no sign of a leak. It's been hot outside so contraction in cold weather wouldn't explain it.

And I drove 2 hours home from the cottage without any overheating.

Any thoughts? The dealer is closed until Tuesday because of a holiday.

Thanks in advance.
