Replacement PCV Crankcase Breather Hose for Audi PCV Relocation, 06E103217M

Your factory PCV breather hose has one job: keep your crankcase ventilation system airtight. After a decade-plus of heat cycling, oil vapor, and general neglect, most stock hoses fail at that one job. Cracked, brittle, leaking vacuum where it shouldn't be, throwing fault codes you didn't ask for. Sound familiar?

The Vorsprung Autowerk Replacement PCV Crankcase Breather Hose is a direct, OE-matched fix, built around the same quick-disconnect geometry as OE part 06E103217M. On its original 3.2L V6 platforms it's a straight stock-for-stock swap. But where this line really earns its keep is on the Audi 3.0T Supercharged, where it's become the go-to hose for custom PCV relocation and catch-can builds. If you're routing your 3.0T's PCV setup away from the factory location, this is the hose we built it for.

Why Your Stock Hose Is Probably Already Failing

Factory breather hoses are made to survive the warranty period, not your ownership period. Constant exposure to oil mist, fuel vapor, and under-hood heat breaks down the material over time until it cracks, splits, or just stops sealing. The result: unmetered air sneaking into your intake, erratic idle, oil mist where it shouldn't be, and a check engine light that shows up right when you don't need it.

Key Features & Specifications

• ✅ Built for 3.0T PCV Relocation 
• ✅ Direct OE Fitment (3.2L V6) — Replaces factory part 06E103217M (and supersessions) exactly on its original platforms, matching the factory quick-disconnect geometry for a secure, leak-free lock.
• ✅ Thermal & Chemical Resistance — Built from heavy-duty, reinforced polymer engineered to shrug off high under-hood temps and constant exposure to oil and fuel vapor. It won't turn brittle on you two summers from now.
• ✅ Emissions & Performance Protection — Maintains correct crankcase pressure regulation, stops oil mist seepage, and keeps unmetered air out of your intake tract where it causes idle and fueling headaches.
  

Bottom line: whether you're replacing a tired stock hose on a 3.2L V6 or relocating your 3.0T's PCV system for a catch-can install, this hose seals it up and stays out of the way.

Note: This hose matches OE part 06E103217M. Always confirm your chassis code and intended routing before ordering to ensure the fitting works for your specific build.

Fitment

This hose is a direct OE replacement across Audi's 3.2L V6 lineup (A4, A6, A8, and their S/allroad/Cabriolet variants), and is also widely used for custom PCV relocation and catch-can builds on the Audi 3.0T Supercharged.

Confirm your chassis code and intended routing before ordering — several PCV hose variants (06E103217L, 06E103217AA, 06E103217AF, etc.) exist across model years and are not interchangeable.
