16825/P0441/001089 - EVAP Emission Control Sys: Incorrect Flow
Possible Symptoms

Possible Causes

Evaporative Emission (EVAP) Canister Purge Regulator Valve (N80) faulty/jammed
Evaporative Emission (EVAP) Canister Purge Solenoid Valve (N115) faulty/jammed
Evaporative Emission (EVAP) Canister Sealing faulty

Possible Solutions

Check Evaporative Emission (EVAP) Canister Purge Solenoid Valve (N115)
Check Evaporative Emission (EVAP) Canister
Perform Basic Setting

Special Notes

When found in the NAR 1.8T Audi A4 1.8T check TSB 24-08-78 or 2010268/3 or Pass-Thru equivalent TSB
When found in the NAR 1.8T VW Passat 1.8T check TSB 01-09-09 or 2005554 or Pass-Thru equivalent TSB
Note: The Passat 26E5 or "R5" recall includes the same software update
Make sure the quick release lines for the N80 valve and vacuum line to LDP are not crossed.
This can also make the engine hard to start after filling up the fuel tank.

Good luck.
