DIAGNOSTIC TROUBLE CODES

DTC	Description
P0441	EVAP Emission Control System Incorrect Purge Flow

TECHNICAL BACKGROUND

Production tolerance in Diagnostic Module Tank Leakage (DMTL) pump could cause a false flow reading.

PRODUCTION SOLUTION

Updated DMTL pumps as of pumps' production date September 2012. (Pumps marked with a dot (color may vary blue, green, white and yellow), implementation dates from plants unavailable at this time).

NOTE: Dot color may vary blue, green, white and yellow.

SERVICE

NOTE: A completed DMTL function test is required for reimbursement.

Perform the following steps to test the DMTL system.

Start Engine.
Connect VAS-Tester to vehicle.

Start "Vehicle Self-Diagnosis".
Open "On Board Diagnostic (OBD)".
Start Diagnostic session with "01 Engine Electronics".
Select "011 Measurement Values".
Select "MVB 30".
Make sure the second "0" from the right in row one changes to "1".
If the bit changed to "1' or is already "1" exit MVB.
Enter "006 Basic Settings".
Select "Basic Settings 70".
Select "Activate".
Check maximum value in row one (lower window).

Tip No engine restarts necessary!

If maximum value is less than 70%, DMTL is OK, replace the Purge Valve.

If maximum value is greater than 70%, DMTL is not OK and needs to be replaced.

If maximum value is close to 70%, rerun the test 2 more times to get a more accurate reading.

NOTE: If percentage value is in question, please contact the Volkswagen Technician Helpline for further instructions.

NOTE: When replacing the DMTL, ONLY replace the pump and not the whole assembly. Claims with DMTL assemblies will be subject to warranty review and potential debit.
