I have a 1998 audi a4 2.8 code po441 keeps coming up could tell me what it means


This is what I got from a google search;
p0441 (vag 16825) = EVAP Emission Contr.Sys.Incorrect Purge Flow
The evap system has several valves and solenoids that control purging of evap gases from the fuel system. Most likely one of these valves is not opening/or is stuck open. If something is stuck open it could actually lead to the above 16839 fault code.
Hope that helps.

was told computer diagnostic tool woul not tell me exactly whats wrong with my evap emission control system


Most of them acually do now-a-days. It sould at least tell you if there is a vaccum leak...of course you may be able to hear that anyways. I have a 2001 VW Passat, and my computer gives codes for all the EVAP systems...EGR, vaccum, O2 sensors...
