Oil Pressure Relief Valve — VAG 1.8 TSI / 2.0 TSI / TFSI GEN2 | Audi, VW, Skoda, Seat
Fix Oil Leaks from the Valve Cover Area and Protect Your TSI Engine from Pressure Damage.
Oil leaks from the cylinder head area, oil pressure faults, or a soaked valve cover gasket on your 1.8 or 2.0 TSI/TFSI? The oil pressure relief valve is often the overlooked culprit. When it fails or sticks, excessive oil pressure builds up in the cylinder head — forcing oil past gaskets and seals.
This is a direct OEM-spec replacement valve for the GEN2 VAG 1.8 and 2.0 TSI/TFSI cylinder heads — one of the most common fixes for persistent oil leaks on these engines.
Why Replace the Oil Pressure Relief Valve
- Stops Oil Leaks: A stuck-open valve lets oil pressure exceed design limits, forcing oil past valve cover and camshaft seals.
- Protects Engine Seals: Correct oil pressure regulation prevents premature seal and gasket wear.
- Common TSI Fix: On GEN2 TSI/TFSI engines, this valve is a known weak point — replacing it is often what finally stops a recurring leak.
- OEM Spec: Direct replacement for 06H103156.

Pro Tip: If you've already replaced the valve cover gasket on your TSI and the oil leak returned, the pressure relief valve is the next suspect. A new gasket won't hold if excessive oil pressure keeps pushing through it.
