b8.5 s4 coolant leak help

[audinoob45]

So i have a coolant leak and i wanted some input on common places these cars leak from. it is a slow leak. I started smelling it when walking in front of my car after a drive about a week ago, checked my coolant level yesterday and it there was allitle left in there. filled it up yesterday morning, drove about 50 miles, and only about an 8th of the tank was empty, the rest of it was still full. the interesting thing is that the leak spots are also on the upper part of the aftermarket grill of the car. i made a video of the engine bay of the car, can you guys please tell me where you assume its coming from? If you hear any abnormal sounds from the pulley or waterpump? This is my first audi and first supercharged car so i dont know if it sounds "normal". I have posted a link of the video below. I have also posted a link of a picture of the plastic cover which has some white coolant spots looking like some coolant had exploded on it.

I was in a similar situation, my water pump had a slow leak from a bad seal and was draining down the front of the motor and landing all over the plastic tray. Yours might be getting on the belt and splashing around. The SC has to come to change it. I think you need to do a good rinse down before trying to find the exact spot.

Look here for the diy on water pump and maybe you can pinpoint it.

I would be prepared for your WP to fail. When it does, you will be dead in the water. Be very careful not to drive anywhere off the beaten track until you find the definitive answer to where the leak is coming from. It might be a good Idea to replace the T stat if and when you have the SC off.
