NOTE: This TSB only applies to MY20 & MY21 Atlas and Atlas Cross Sport vehicles with 2.0T engines.

One or more of the following fault code(s) must be stored in the ECM:

DTC DESCRIPTION

DTC	Description
P052A	Cold Start "A" Camshaft Position Timing Over-Advanced Bank 1
P054A	Cold Start "B" Camshaft Position Timing Over-Advanced Bank 1
P0300	Random/Multiple Cylinder Misfire Detected
P0301	Cyl.1 Misfire Detected
P0302	Cyl.2 Misfire Detected
P0303	Cyl.3 Misfire Detected
P0304	Cyl.4 Misfire Detected

NOTE: DO NOT diagnose or replace any components for the above fault(s) before performing the update function as explained in this bulletin.

TECHNICAL BACKGROUND

Improvements made to ECM software for better combustion stability during catalyst heating and engine warmup, and changes to misfire detection thresholds for improved misfire recognition during catalyst heating.

NOTE: Volkswagen has implemented a 15 year/150,000 mile extended warranty covering a one-time software update in the event these fault codes are stored. See Warranty Policy Bulletin VWP-23-08 for details.

PRODUCTION SOLUTION

Improved software implemented into production.

SERVICE

Procedure:

Inspect the software level of the ECM and compare to the software table below. If the software level in the vehicle is current, this TSB does not apply and further diagnosis is needed.
If the software level is not up-to-date, continue with the software update as listed below.

NOTE: Repairs outside the scope of this TSB are not applicable and not covered under this warranty extension. Refer to VWP-23-08 for additional details.

Update-Programming Procedure:

WARNING: Critical Warning : The Midtronics battery charger must be connected to the vehicle battery for the duration of the programming, to ensure the battery state of charge remains above 12.5 volts during the update process. If the battery drops below 12.5 volts, the programming could fail which may result in damage to the control module. Control modules damaged by inadequate voltage will not be covered under the warranty policy. The technician should verify the vehicle voltage prior to starting the update process, and should monitor the voltage for the duration of the update.

WARNING: Radiator Fan(s) may cycle ON high speed during the Update Process! There is a risk that personal injury may result if contact is made with spinning fan blades.

Keep hands and all objects away from Radiator Fan(s) during Update Process!

CAUTION: Prior to launching the ODIS service diagnostic applications and starting control module update process, confirm tester screen saver and power settings in accordance with Special Tools and Equipment - Service Information Circular # VVT-12-02. Failure to do so may result in the tester entering power save mode during data transfer, and subsequent control module failure.

When using a VAS 6150/X or 6160/X tester in conjunction with a VAS 5054A wireless transmitter head for a flash procedure, connect a USB cable between the transmitter head and the tester. Failure to do so may lead to errors during the flash procedure. VAS tools must only be used with their power adapters plugged in. Under no circumstances should they be used on battery power alone during the programming procedure.

To Update-Programming using Software Version Management (SVM), review and follow instructions in Technical Bulletin Instance 2014603 "Software Version Management".

The SVM Process must be completed in its entirety so the database receives the update confirmation response. A warranty claim may not be reimbursed if there is no confirmation response to support the claim or action is carried out that is not explicitly stated in the Technical Bulletin.
Update the -J623- Engine/Motor Control Module using the SVM Unit code as listed in the table below:

2021 Atlas Cross Sport	2.0T (DCGA)	3CN 906 259 F	0001	3CN 906 259 F	0002	4548

NOTE: The procedure can be found in GFF under Functions/Component Selection, Software Version Management, Adapting Software.

Ensure attached ECM/TCM Tuning Form has been completed and signed by customer as required in SVM Technical Bulletin Instance 2014603.

Perform a road test of the vehicle. If faults return, further diagnosis is needed and is not covered under this TSB.
