07K103495F – PCV Pressure Control Valve / Oil Separator – Audi RS3 8V.5 & TTRS 8S – DAZA / DNWA
This genuine Volkswagen/Audi PCV Pressure Control Valve (Oil Separator) is designed specifically for the 2.5 TFSI DAZA and DNWA engines found in 2017–2018 Audi RS3 (8V.5) and Audi TTRS (8S). This component manages crankcase ventilation, controls internal engine pressure, and recirculates oil vapors — essential for preventing blow-by, boost leaks, and carbon buildup.
A failing PCV unit is common on tuned or higher-mileage DAZA vehicles and can lead to boost issues, erratic idle, oil leaks, or drivability problems. This OEM part is the correct replacement for all pre-2019 RS3/TTRS models.
