Audi PCV Pipe - Genuine Audi 06E103207AP

Product Information

PCV Pipe

The PCV pipe carries pressurized crankcase gasses from the PCV valve (air/oil separator) to the intake side of the engine, where they're burned off as part of normal combustion. It's a small part, but a critical one: when it hardens, cracks, or splits, the resulting vacuum leak throws off the engine's fuel trims and idle quality.

This pipe sits in a hot, oil-vapor-rich environment under the supercharger, which is exactly why the factory plastic becomes brittle over time. It's a common companion failure to the PCV valve itself, and a smart add-on any time the supercharger is off the car for other service.

PCV Pipe Failure Symptoms

• Cracks, breaks, leaks: Constant exposure to oil vapor, heat, and pressure slowly breaks down the plastic, eventually causing a vacuum leak.
• Broken connectors: The plastic clips and connectors become brittle with age and are easy to snap during removal or other nearby service work.
• Check Engine Light: Unmetered air from a cracked PCV pipe commonly triggers a CEL for an air intake leak or related airflow fault.
• Rough idle or misfire: A large enough vacuum leak throws off idle quality and can cause a misfire, especially at low RPM.
• Oil residue on or around the pipe or adjacent components: Escaping crankcase vapor tends to leave visible oil residue on the pipe itself and the parts around it.

PCV Pipe FAQ

Is this a genuine Audi part or an aftermarket reproduction?
This is a genuine Audi OEM part, part number 06E103207P, not an aftermarket reproduction.

I have a 2013 S4 or S5 — is this the right pipe?
It depends on when your car was built. Most 2013 S4/S5 take this AC pipe, but early-production 2013 cars take 06E103207P instead. If you're not sure, check our genuine 06E103207P listing or send us your VIN and we'll confirm which one you need.

How do I know if my PCV pipe needs replacing?
Common signs are a check engine light for an air intake leak, rough idle or a misfire, and visible oil residue around the pipe or adjacent components.

Is this a direct bolt-on replacement?
Yes, it's the genuine factory part and drops in exactly where the original pipe lived, no modification required.

What should I inspect while replacing this pipe?
Check the surrounding clamps, the PCV valve itself, and the PCV-to-supercharger adapter pipe at the same time, since brittle plastic in one spot usually means the neighboring pieces aren't far behind.

Complete Your Build

Already in the valley? Pair this genuine pipe with:

• OE Ultimate Under Supercharger Kit (B8.5 & C7) — if you're already replacing the PCV valve or thermostat, do this pipe in the same service window.
• Genuine Audi PCV Pipe (06E103207P) — the correct part for early-production 2013 S4/S5, instead of this AC version.
• Vorsprung PCV Pipe, 06E103207AC cross-reference — a lower-cost cross-reference alternative to this genuine part, same fitment.

Drive the difference. Drive Vorsprung.
