Audi A4 B8 A5 Q5 A6 C7 TT VW Beetle 1.8 / 2.0 TFSI Oil Separator 06H103495A / 06H103495B

Product overview

A new oil and gas separator for 1.8 and 2.0 TFSI petrol engines, cross-referenced to an extensive list of OE-reference numbers: 06H103495A, AB, AC, AH, B, C, E and J. This crankcase ventilation unit separates oil from blow-by gases. When its internal diaphragm fails, owners often notice a high-pitched whistle at idle, an unstable idle speed, rising oil use or a check engine light.

Vehicle compatibility

The listing model list covers the Audi A3 8P, A3 Sportback and Convertible, A4 B8 sedan, Avant and Allroad, A5 coupe, Sportback and Convertible, A6 C7, Q3, Q5 and TT/TT Roadster 8J with 1.8 TFSI, 2.0 TFSI and 2.0 TFSI quattro engines, from approximately 2003 to 2017. The part listing also references the VW Beetle, and the fitment table includes Volkswagen, Skoda and Seat TSI and TFSI models. Entries for diesel and BMW models appear in the extended table but do not match this petrol component and should be disregarded. Please confirm by OE-reference number or VIN before ordering.

Technical specifications

Installation requirements

The separator mounts on the side of the cylinder block. Depending on the model, access may require removal of the intake manifold or surrounding pipework. Clean the mating face, fit new seals and tighten to specification. Installation by a qualified mechanic is recommended. Clear stored fault codes afterwards and confirm a smooth, quiet idle.

Fitment checks before ordering

Separator revisions differ between early and later engine generations, and the external hose connections can vary. Please send your VIN or the number on your current unit so we can confirm compatibility before ordering.
