I keep getting the 441 error code on my 2000 A6 Avant, referencing to insufficient purge flow. Does anyone have a hint as to what to look for??

Thanks!!

 

Evap purge valve stuck closed or a broken vacuum line from the purge valve to the engine. Do a search in the a6 and a4 forums. Operation and location is the same on both vehicles and theres plenty of posts to help you along.

 

i just replaced all vacuum lines, but i will ckeck for the valve.
thanks for the input!

 

If yo ujust replaced all the vacuum lines you may have one incorrectly routed. Also make sure the purge valve is plugged in. Both mechanically and electircally.
