Replacement of the fuel filter

The fuel filter in Audi A4 is designed in such a manner that it does not need to be changed throughout all life of the engine. It is very good, as for filter dismantle it is necessary in quattro to disassemble all fuel tank. And it in turn demands dismantle of the back bridge.

Therefore replacement of the fuel filter is necessary only in case of functional infringements.

The fuel filter (2 – with pipelines 1 and 3) in models with a drive on forward wheels settles down precisely before the right back wheel niche on the car bottom.


The fuel filter (2) models quattro is established on the right forward end of a fuel tank. Besides, by figures are shown:
1 – топливопровод from a fuel tank to the filter; 3 – топливопровод from the filter to injection system.
