MAHLE KX178D is the correct “2-hole” (A-style housing) fuel filter element for many 2005–2013 Volkswagen 1.9L/2.0L TDI applications. It’s a direct-fit replacement that meets or exceeds OE specs and is built to MAHLE’s OE filtration standards for clean, consistent fuel delivery.

• Direct replacement for VW TDI A-style (“2-hole”) fuel filter housings
• Designed to meet or exceed factory filtration performance

Selector note: This is the A-style / “2-hole” filter. The housing has a star-shaped top with individual tabs for each cover bolt. If your housing does not have individual tabs, you likely have the B-style (“1-hole”) housing—see KX228D instead.

Specs (from supplier listing): Height ~142 mm overall; sealing Ø ~38 mm. (Dimensional values from listing; verify against your housing before installation.)

FAQ

Check your filter housing lid: the A-style (2-hole) has a star-shaped top with individual tabs for each bolt. If that matches, KX178D is the right element.

Yes, if you have the A-style housing on the Jetta (’05–’13), Jetta SportWagen (’09–’13), or Golf (’10–’13) with BRM/CBEA/CJAA engines. Always compare your housing style before ordering.

Yes—vehicles with the B-style housing use MAHLE KX228D (“1-hole”).

Most quality elements include required seals. Inspect the kit on arrival and replace all seals during service to prevent air leaks.

Prime the system per VW procedure, keep the housing clean, and torque the cover evenly. Dispose of the old element responsibly.
