Fuel filter Audi A6 C7 (2011–2018)

About this part

The fuel filter stops dirt and water before they reach the injectors. Modern injectors work to tolerances of a few thousandths of a millimetre: a particle that gets through wears them, and an injector costs far more than a filter.

The usual interval is between 30,000 and 60,000 kilometres, and on diesels it often coincides with a major service. An engine that misfires under load or starts poorly may have a clogged filter. On diesel engines the filter also separates condensation water, and in winter a clogged filter is the most common cause of a hard start.

It can be inline, a cartridge, or part of the pump module in the tank. Connections and flow rate matter, and on diesels also the water separator and any sensor. On a vehicle that is a few years old, after standing for a long time, condensation and deposits can build up in the tank: the filter is the first thing to check.
