There are a variety of symptoms that can indicate that the time has come to replace your Audi fuel filter. These symptoms include a general sense of decreased engine power, a hesitation when you press the fuel pedal, particularly if you're making a sharp fuel demand, such as for passing, misfiring while in motion, a sudden surge of power that is not in response to you applying pressure on the pedal, but rather seems to come out of nowhere, and a distinct dragging and lagging sort of refusal to pick up speed that can be complemented with an increasing tendency to stall out. Not surprisingly, most of these symptoms reflect the engine's increasing struggle to draw the fuel it needs through a filter that is dirty or almost completely clogged. When an Audi fuel filter is in this condition, it can cause expensive damage to other parts of the fuel system, such as the fuel injectors, as their delicate inner parts will not tolerate the particles that a too full filter can allow to escape, and their tiny tips are easily clogged. If the Audi fuel filter becomes completely clogged, your vehicle may not run at all, as the combustion system simply won't be able to get the fuel it needs.
