Genuine Audi Volkswagen Engine Sealing Gasket 06M103517B

Genuine Audi VW PCV Valve Gasket 06M103517B - Oil Separator Seal for 2.9T/3.0T Engines

The Genuine Audi VW PCV Valve Gasket 06M103517B seals the positive crankcase ventilation (PCV) oil separator assembly to the engine. This small OEM gasket sits between the oil separator and the cylinder head cover, keeping crankcase gases, oil vapour, and vacuum pressure contained inside the PCV circuit. Whenever the PCV unit is removed for service, this gasket must be replaced — refitting a compressed, heat-aged seal is one of the most common causes of repeat oil leaks on Audi 2.9T and 3.0T V6 engines.

On the B9 and C8 generation Audis, the PCV oil separator is a hard-working emissions component. It separates oil mist from blow-by gases before they are recirculated into the intake, and it operates under constant heat, oil exposure, and vacuum load. The 06M103517B gasket forms the airtight joint between the separator housing and the engine. When this seal hardens or takes a permanent compression set, the joint no longer holds: oil weeps down the engine, unmetered air enters the crankcase circuit, and the engine management system can flag lean-mixture or PCV performance faults.

A failing PCV gasket usually announces itself gradually. Look for a faint oil weep or dampness around the oil separator area, a whistle or hissing sound from the top of the engine at idle, fluctuating idle speed, or check-engine warnings related to crankcase ventilation. Because the leak path is small, drivers often notice a burning-oil smell before they see any drip — oil mist escaping the joint lands on hot engine surfaces. Replacing the gasket with the genuine 06M103517B during PCV service restores the sealed joint and eliminates these symptoms in one visit.

Genuine VAG gaskets are engineered for this exact joint. The 06M103517B matches the original seal profile and compression behaviour, so it seats correctly against the separator housing and the mating engine surface with no trimming or sealant. It is specified for the oil and heat environment of the 2.9T/3.0T V6 crankcase circuit — the same part fitted at the factory. For any engine work around the top end, our Engine Parts collection carries the related genuine seals and service hardware your technician may need alongside.

Replacement is a technician-level job performed whenever the PCV oil separator is removed — which is exactly when this gasket should be fitted new. The separator is unbolted, both mating faces are cleaned of old seal residue, the new genuine gasket is seated in its channel, and the unit is refitted and torqued to the manufacturer's specification. Never reuse the old gasket: once compressed and heat-cycled, it cannot reform a reliable seal. Pair it with a fresh Genuine Oil Filter for Audi, Volkswagen 06D115562 during the same service for a complete oil-circuit refresh.

Why Choose European Auto Spares

Built for Oil and Heat

This gasket lives in hot, oil-laden crankcase vapour. The genuine OEM specification resists hardening and swelling through heat cycles, keeping the PCV joint airtight between services.
