❓ FAQ

A metal-free diesel fuel filter element for the four-cylinder TDI engines. It goes into the filter housing on the engine, so the housing itself is reused and only the element is replaced at service.

1K0127177B, 1K0127434B, 1K0127400K, PF9861, 33832 and C10448. Read the number off the old element before ordering, because the same engine bay was built with more than one filter format.

No, and it does not need one. The body is the element and it seats into the housing already on the engine, so there is no second part number and no plastic lid to order with it.

The multi-layer media holds the fine particulate that would otherwise reach the high-pressure pump and the injectors. A worn nozzle seat shows up first as an uneven idle and rising consumption rather than a fault code, which is why the interval is worth keeping.

Description

Product Overview

The PU 936/1 X is the diesel fuel filter for the four-cylinder TDI engines that VW put in the A3, Beetle, Caddy, Golf and Altea. It is a metal-free element: the body is polyethylene rather than a steel can, which is the format these engine bays use — it slides into the housing on the engine and the housing itself is not replaced.

Filtration on a modern diesel is not about keeping the fuel looking clean. The injectors on these engines work at pressures where a hard particle small enough to pass the nozzle clearance will erode the seat and change the spray, and the first sign of that is usually a rough idle and a rising consumption figure rather than a fault code. The multi-layer media in this element is built to hold the fine end of that range, not just the visible debris.

It replaces 1K0127177B, 1K0127434B, 1K0127400K, PF9861, 33832 and C10448, which covers the numbers the element is commonly listed under in Europe and North America. Read the number off the old element before ordering, because the same engine bay was built with more than one filter format across the model years.

Key Features

Metal-free element — a polyethylene body instead of a steel can, so the housing on the engine is reused and only the element is replaced at service.
Multi-layer media — several layers rather than one, so the coarser debris is caught early and the fine layer is not loaded before its time.
Six cross-references — 1K0127177B, 1K0127434B, 1K0127400K, PF9861, 33832 and C10448, covering the numbers this element is sold under.
Direct fit in the factory housing — the element goes into the existing filter housing with its own seal, without an adapter or a change of lid.
Protects the injectors — the fine layer is what stands between the pump and the nozzle seats, which is where a worn seat turns into a misfire and a smoky cold start.
Correct for the four-cylinder TDI — the 1.9 and 2.0 TDI applications listed here, not the larger six-cylinder units that use a different filter.
Service item, not a repair — an element costs a fraction of one injector, and it is the least expensive part of the fuel system to renew.
Cold-start behaviour — a filter left past its interval restricts flow when the fuel is thick, which is why hard starting in winter is often a filter rather than a glow plug.
No housing to buy — because the body is the element, there is no second part number and no plastic lid to order with it.
One box, one element — supplied on its own, so a service does not need a kit.
