Component Location

A quick and direct guide showing you the exact location of the Positive Crankcase Ventilation (PCV) Valve assembly (often called the pressure control valve) on a 2006-2008 Audi A3 equipped with the 2.0T FSI (EA113) belt-driven engine. No wasted time, no endless talking—just a clear view of where to find it mounted directly on the very top of the plastic engine valve cover, positioned right on the front side facing the radiator and sitting just behind the main plastic engine trim cover.

DIY Friendly Repair Guide

If you are planning to replace this component yourself, knowing its precise location and how to safely unclip the brittle, heat-cycled plastic breather tubes without snapping them is half the battle. This video is designed to save you time and frustration before you even open the hood, making your DIY auto repair much smoother.

Common Bad Symptoms

When this component begins to fail, you might experience several warning signs. Common symptoms of a faulty PCV Valve include an illuminated check engine light (CEL) with diagnostic codes like P0171 (System Too Lean) or P0507 (Idle Control System RPM Higher Than Expected), a wildly erratic or surging engine idle, a loud whistling or hissing noise coming from the top of the engine, and a noticeable drop in fuel economy. Because a torn internal diaphragm creates a massive vacuum leak, a completely failed PCV valve can also cause high oil consumption, oil blow-by leaking past the engine seals, or an oil filler cap that is incredibly difficult to pull off while the engine is idling due to excessive internal vacuum.

Safety First!

Before you start working on your vehicle, always prioritize safety. Make sure the engine is completely turned off and cooled down before performing any work. Always wear proper eye protection and mechanics’ gloves, exercise caution when handling the delicate plastic retaining clips on the vacuum lines, and ensure your working environment is safe before performing any vehicle maintenance.
