Is it OK to leave OBD2 reader under the hood while driving

I have a 2000 W202, C240. Unfortunately, unlike America, in Europe it was not a standard to have OBD2 port in cars built after 96, so mine doesn't have it either. What I have is a 38 pin diagnostic port under the hood. I've bought a 38 pin to 16 pin adapter so that I can connect to my WIFI OBD2 reader. I have purchased DashCommand app that really does a great job. But lots of features like average fuel consumption are only available while driving. I was wondering if it's OK to leave the OBD2 reader connected to the diagnostic port while I'm driving? Can it harm the system somehow?

So long as you secure it so it can't come unplugged, you'll be fine. Underhood heat will kill it, though, so don't drive too long.

Good luck.

I am driving with ScanGauge plugged all the time.
It is scanner with 4 gauge display and endless options that helps you observe sensors and car performance while you drive.
Obviously with OBD plug it is mounted inside the cabin, but the 38 pin plug, just like car computers are behind heat shield from the engine.
