OVERVIEW
Renew the specified fuel filter and regulator assembly
4F0-201-511-E is the Genuine VW/Audi fuel filter with integrated pressure regulator for the specified gasoline fuel systems. The assembly combines fuel filtration and the original regulating function in a metal housing with the factory line connections.
Correct filtration and regulator specification are both essential when replacing this component. A filter that connects physically but has a different regulating arrangement can be unsuitable for the fuel system. Match the complete part number and original connection layout before ordering.
Technical details
- Complete factory number: 4F0-201-511-E.
- Factory specification: factory fuel filter with pressure regulator, revision E.
- Design: metal filter canister with multiple fuel-line connections and marked flow direction, as pictured.
- Quantity supplied: one individual fuel filter and regulator assembly.
One individual filter/regulator assembly is supplied. Fuel lines, retaining bracket, pump, injectors and fuel are separate. This gasoline filter is not a diesel fuel filter.
Common reasons to replace
- The vehicle's applicable maintenance procedure calls for filter replacement.
- Testing identifies excessive restriction or a regulating fault in the filter assembly.
- The housing or connection is damaged.
- The original correct filter is replaced during a contaminated-fuel-system repair as specified.
Check the fuel-system pressure and delivery according to the engine repair procedure. Poor starting or lack of power can have several causes, including pump, wiring, injector and fuel-quality faults; confirm the filter/regulator is responsible before replacement.
