Between 2005 and 2010 Volkswagen used two different fuel filter types, and it can be hard to tell via VIN which filter is in your car. The easiest way is find which filter you have is to look under the hood at the filter cartridge shape.
The two filter designs we call “Early” and “Late”. There are two different VW part numbers that correspond to the two designs.
EARLY: 1K0127434A (sometimes the “A” is omitted)
LATE: 1K0127434B
