Porsche Cayenne 4.8L Oil Separator Diaphragm, 85 mm - 94810723602

When the oil separator membrane dries out and tears, it can admit air that the MAF has not measured. This separate 85 mm membrane is for the Porsche Cayenne 4.8L M48.01 oil separator; its membrane reference is 2000003187.

Vehicle Applications

• Porsche Cayenne 4.8L - M48.01.

When to Inspect the Ventilation Valve

• Whistling or excessive crankcase vacuum.
• Unstable idle.
• Increased oil consumption.
• Oil deposits in the intake.
• Exhaust smoke after warm-up.
• Mixture faults associated with unmetered air.

Confirm the fault by inspecting the membrane, ventilation housing and hoses before selecting a repair.

Additional Symptoms and Inspection

Difficult starting and misfires can accompany the air leak. A whistling sound near the oil separator calls for inspection of the membrane. A damaged membrane may also allow road dust into the engine, contributing to wear; confirm the fault before replacement.

Repair Scope and First Start

This separate membrane allows a failed diaphragm to be serviced without replacing a sound oil separator assembly. At the first start after replacement, the engine may run unevenly while the ECU adjusts its fuel maps. Allow it to run for a while and then restart it.

Important Before Ordering

Compare the installed assembly reference, membrane design and dimensions before ordering. Check the housing and ventilation hoses for damage; a membrane alone may not resolve a cracked housing.
