Q7 2013 v6

Hi everyone, I have the usual coolant leak from somewhere on my 2013 q7 3.0 tdi.

It doesn't seem to lose it when just running around on short journeys , but on a 50 mile trip or something like that it loses some coolant. The car runs absolutely fine and at the correct temperature.

Has anyone else has this type of symptom?

If so ,what was the fix?

Everything I read online is say about looking in the v for coolant but you can't seem to see anything as it's so tightly packed in there, the only place I've seen coolant is down the right side of the waterpump as you look at it dripping down slightly, the car was facing slightly down hill and leaning that way. I have also noticed the pump has a broken bolt on it so will taking it of to remove that aswell. So not sure if it's coming from that, but it doesn't look like it. Thanks 👍
