Condition

Update Programming for Engine Control Module and Transmission Control Module, Slight Hesitation Concerns

Tip:
This software update is designed to re-program both the ECM and TCM with new software. The reprogramming itself should carry out both updates without technician intervention. Please ensure both ECM and TCM software has been updated after the flash is performed

This software update is for slight hesitation related concerns for DSG equipped vehicles only.

Note:
The supplied software for slight hesitation is not associated with stalling or other performance issues.

If the ECM/TCM fault memory contains faults, these faults must be addressed before performing this Technical Bulletin.

If no fault codes are found in the ECM/TCM fault memory: DO NOT diagnose or replace any components before performing the update function as explained in this bulletin.

Technical Background

Service

Update-Programming Procedure:

Tip:
To Update-Programming using 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.

Note:
Prior to launching VAS-PC application and starting control module update process, confirm tester screen saver and power settings in accordance with Special Tools and Equipment - Service Information Circular # VSE-08-18.

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 6150/5051B or VAS 5052A tester in conjunction with a VAS 5054A wireless transmitter head for a flash procedure, please connect a USB cable between the transmitter head and the tester. Failure to do so
may lead to errors during the flash procedure.





^ Update the Engine Control Module using the SVM Unit code as listed in the table.





^ Update the Transmission Control Module using the SVM Unit code as listed in the table.





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





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