This car has been nothing but a nightmare but slowly I'm trying to get it up and running and to pass inspection. Trying to knock out check engine codes one by one.
I recently replaced the Mass Airflow Sensor, Coil Pack and gave it a full tune up. There is 1 check engine code still remaining P0441. From the research I found I changed the gas cap but the code is still there. Any information would be greatly appreciated! Thx

 

what did you ever find out about the p0441 code? i am having the same problem wih my 2006 tourereg.

 

I replaced the charcoal canister and the pressure valve off the intake manifold. U also may want to consider a smoke test. It could be a hairpin leak in any of the evap hoses. Id do that first before spending money on replacing parts. Just a suggestion.
Good Luck & let me know how u make out.
