I just bought my s4 as is it has 88 thousand miles and the valves were never changed and i noticed oil and coolant all under the front of the car but not pooling more like a slow steady leak could it be the pcv valve or something else major i’m new to the s4 platform and don’t know to much about the car

The PCV is a common coolant leak concern on the 3.0T, as it sits in the V under the supercharger and has coolant routed through it, I assume to keep it cool. There's threads about the CCBA/CGXC/CTUB (whichever 3.0T you have) PCV out there. Also, you might find more activity at this B8 S4 forum: https://www.audizine.com/forum/forum....php/163-B8-S4 The one here seems pretty quiet.
