My car throws water from the exhaust

Friends car is coming from the exhaust water, I wonder why this can happen? This situation has been around for a very long time. People around you notice and say.
Vehicle 2011 MODEL 206+ at 40000.

Water coming out of the exhaust indicates that the vehicle's engine is good.

Isn't there a problem? Would the trip computer fail if there were trouble?

The vehicle burns cig gas in the first works. I got 307 in the exhaust inspection. I came to the water.

Then there is no problem to worry :) I suspect there is a problem. Thank you very much friends ..
