What to Compare Before Purchase

  • Match 04E103175AC exactly, or confirm the superseding number in a VIN-specific catalog.
  • Confirm the vehicle engine, market and production date.
  • Compare the hose-port count, diameter, angle and orientation.
  • Compare the housing shape, flow-direction markings and connection points.
  • Compare every product image with the valve currently installed.
  • If any detail differs, request fitment help before ordering or installation.

Diagnostic and Installation Note

A warning light, vacuum leak, oil-consumption concern or drivability symptom does not identify one exact valve. Diagnose the crankcase ventilation system first. Use vehicle-specific service information to confirm the valve location, flow direction and replacement procedure.

Product FAQ

Will this 04E103175AC valve fit my vehicle?

Catalog references associate this crankcase-breather valve family with selected VW Golf and Jetta, Audi A1 and A3, Seat Leon, and Skoda Octavia applications. Confirm the exact OE number or supersession, engine, market and VIN before ordering.

Which number should I match?

Match 04E103175AC. Some catalogs cross-reference 04E103175C and 04E103175M, but interchange should be confirmed for the exact VIN rather than assumed.

What physical details should I compare?

Compare hose-port count, diameter and angle, housing shape, connection points, flow-direction markings and every product image.

Does a PCV-related symptom prove this valve is faulty?

No. A symptom or fault code requires diagnosis and does not identify one exact replacement part. Confirm the system fault and the correct OE number first.

Can NexuParts help compare the valve?

Yes. Email the product link, VIN, original OE/OEM number, vehicle year, model and engine, and clear photos of the original valve to info@NexuParts.com before ordering.
