Can anyone tell me when a fuel filter should be changed on an '02 S4? I've been told as often as twice per year but there's no manufacturer recommendation that I can see. I was under the impression that if your fuel filter needed changing it would cause obvious mechanical problems.

once every couple of years or 3 its not specific in that way so basically its up yo you or if you start getting fuel related problems or it rusts away lolive seen them on much older cars with a few hundred Ks and still got the original filter on or the last one the dealers fitted in the service intervals
