C class 2017 1.6 diesel coolant leak

[Flatlander]

Hi
I've just bought a 2017 c class 1.6 diesel I believe it's the Om626 engine
It's loosing coolant I've checked it for external leaks but can't see anything
It doesn't pressurise the system or overheat on the gauge
I'm very concerned it's an internal leak
I'm going to do a road test top it up before hand the check the loss after a few miles to get an idea

Has anyone any experience on this issue please?

I bought it from a dealer but know it will be a bun fight ref warranty
