Coolant leak and oil leak. 2007 A6 3.2 quattro

My coolant is leaking and it’s not from the hoses at the top or the upper radiator hose because I just replaced them, is this is common issue that someone would know where it leaks from? Would really help
also
my oil is leaking I know that it is leaking somewhere from the top of the engine because when I look it’s leaking from the top and dripping all over everything to the bottom where the lower oil pan is
any advice on how to find out where these leaks are coming from?
I’m new to Audi’s but I usually always work on my own car so I’m trying to fix it without going to a shop. thank you for your time

EDIT:

Also if I let the car sit and not run it the coolant barely leaks almost nothing . Another thing is for the oil leak is it’s coming from the rear side of engine ,drivers side , when I point a flashlight from underneath I can see the oil is leaking not only on the bottom but is starting from the upper level too

For the coolant leak I have two suggestions:
1. I have "heard" people state that the coolant reservoir can have tiny cracks that could leak.
2. Check out your AC heater control valve for leaks. If it was worked on in the past and was not properly sealed, it could be leaking coolant.

For the oil leak:
Check out your oil filter housing cover.
