Audi Crankcase Vent Valve 06E103245E | Vorsprung

Crankcase Vent Valve, 06E103245E

Rough idle, a whistle from the engine bay, or oil showing up where it shouldn't: a tired crankcase vent valve causes more driveability headaches than a part this small has any right to. It regulates crankcase pressure and manages blow-by gases, and when the diaphragm inside wears out or sticks, you'll feel it in how the engine runs.

The Vorsprung Autowerk 06E103245E is a direct replacement for the original valve on the Audi 3.2L engine, and it's also the valve most commonly used for PCV relocation on the Audi 3.0T.

Two Ways to Use It

3.2L Original Replacement: If your 3.2 has a failed or aging crankcase vent valve, this is the correct replacement part. It restores proper crankcase ventilation and should resolve the driveability problems that come with a worn valve.

3.0T PCV Relocation: The factory PCV arrangement on the 3.0T EA837 supercharged platform is a known weak point, buried under the supercharger where it's miserable to service. Relocating the valve to a more accessible spot is a popular, proven way to deal with it, and the 06E103245E is the valve most relocation builds are designed around.

• ✅ Direct OEM cross-reference: 06E103245E
• ✅ Correct replacement valve for the naturally aspirated 3.2L FSI V6
• ✅ The valve used in 3.0T EA837 PCV relocation builds, including our own
• ✅ A small part that prevents an outsized headache when it fails

Bottom line: whether you're fixing a tired 3.2L or relocating a 3.0T's PCV system, this is the valve for the job.

Signs Your Crankcase Vent Valve May Need Replacement

• Rough or unstable idle
• Whistling or hissing from the engine bay
• Oil consumption or oil residue in the intake tract
• Check engine light with fuel trim or lean-condition codes
• Vacuum or boost leak symptoms

Crankcase Vent Valve FAQ

Will this fit my A4 or A6 3.2L V6 as a direct replacement?
Yes. It's a direct OEM cross-reference (06E103245E) for the naturally aspirated 3.2L FSI V6 in the A4 (2005-2008) and A6/A6 Quattro (2005-2011).

Will this bolt straight into my supercharged S4, S5, A6, A7, A8, or Q7?
Only as part of a PCV relocation setup. It's the valve most 3.0T EA837 relocation builds, including our own, are designed around, but it won't drop into the stock PCV location on its own.

What symptoms show this valve is failing?
Rough or unstable idle, whistling or hissing from the engine bay, oil residue in the intake tract, a check engine light for fuel trim or lean-condition codes, and general vacuum or boost leak symptoms.

Do I need anything else to do a PCV relocation?
Yes. This valve is one component. Pair it with our PCV Relocation Oil Separator and Billet PCV Breather Quick Connect to build out the full relocation.

Is this a genuine Audi part or aftermarket?
This is an OEM cross-reference part, not an aftermarket reproduction, cross-referenced to Audi part 06E103245E.
