SERVICE

REQUIREMENTS

Vehicle must meet ALL of the following criteria.

Procedure is valid only for vehicles that show the OE code in the OTIS View Campaign inquiry screen on the day of repair.
Vehicle must be within the Limited New Vehicle Warranty.
Procedure must be performed within the allotted time frame stated in this Technical Bulletin.

TIP: Procedure must also be performed on applicable vehicles in Dealer inventory.

PROCEDURE

Raise hood, inspect for white dot located on accessory drive belt tensioner.

Fig 1: White Dot On Accessory Drive Belt Tensioner
If white dot is present, close out the Required Vehicle Update in O.T.I.S. Input appropriate code.
If white dot is not present, follow instructions to perform update programming (Flashing) of transmission control module.

NOTE: When performing the reflash procedure, ALL DTCs for all systems are erased. DTCs linked to Guided Fault Finding function tests will be lost. Therefore, always address stored DTCs for Customer concerns unrelated to the reflash procedure first.

The following "Update - Programming" (flashing) process may overwrite any "TUNED" ECM or TCM programming. A "TUNED" ECM or TCM is described as any ECM or TCM altered so as to perform outside the normal parameters and specifications approved by Volkswagen of America, Inc.

If you encounter a vehicle with a "Tuned" ECM or TCM, prior to performing the "Update - Programming" (flashing) procedure:

Your Dealership should place the vehicle owner on notice in writing, that their ECM or TCM was found to have been tuned, and that any damage caused by the tuning of the ECM or TCM (including any adverse emissions consequences) will not be covered by Volkswagen of America, Inc. warranties.
For any repair requested by the owner under warranty or outside warranty that requires flashing, which will automatically wipe out the "Tuning" program, your Dealership should advise the owner of the above and get his written consent (see attached ECM / TCM Tuning form) to the flashing procedure.

TOOL REQUIREMENTS

VAS 5051 or 5052 (with Base CD V.08.00.00 and the Brand CD V.08.64.01 or higher) with old diagnosis logs erased prior to start.
"Update - Programming" (flashing) CD W42TOURBMXSHIFT.

NOTE: Additional copies of the "Update - Programming" CD (Literature Number W42TOURBMXSHIFT) may be ordered from the Volkswagen Technical Literature Ordering Center at vw.ddsltd.com, or by calling 1-800-544-8021 from 8:00 a.m. to 8:00 p.m. EST Monday through Friday. This number can be dialed in both the United States and Canada.

VEHICLE REQUIREMENTS

Battery MUST have minimum no-load charge of 12.5V (failure to maintain voltage during update process can lead to ECM / TCM failure) (you must use an approved battery charger to maintain battery voltage).
VAS 5051: connected to vehicle and to 110V AC Power supply at all times during procedure.
VAS 5052: connected to vehicle with battery voltage requirements met.
Any appliances with high electromagnetic radiation (i.e. mobile phones) switched OFF.
No Stored DTC's, erase any stored DTCs.

NOTE: Non-observance of the following points may lead to ECM / TCM failure! VAS 5051 or 5052 must always be connected to the approved power supply at the approved voltages. Under no circumstances should the power supply be interrupted or the diagnostic connector unplugged during the flash procedure. Any appliances with high electromagnetic radiation (i.e. mobile phones) must be switched OFF.

"UPDATE - PROGRAMMING" (FLASHING) PROCEDURE, CHECKING FOR UPDATE MATCH

Switch ignition ON.
Switch VAS 5051/5052 ON and insert flash CD into CD drive as soon as start screen appears.

NOTE: You must return to the start screen before starting a new (flashing) session, otherwise the flashing CD will not be recognized by the tester.
Select "Vehicle Self Diagnosis" mode.

Similar screen appears. Using the scroll bar to the right of the screen:

Select "Update - Programming" option at bottom of screen (arrow).

NOTE: The "Update - Programming" function is only available when the inserted flashing CD level and current vehicle TCM level are different.

If "Update - Programming" does not appear:

Programming (flashing TCM cannot be performed, continue to diagnose condition.

If software level DOES NOT match the level indicated on Flashing CD:

"Update - Programming" (arrow) appears.

PRIOR TO PERFORMING PROCEDURE TO "UPDATE - PROGRAMMING" (FLASH) THE TCM

ALL fault memories must be interrogated and erased.

NOTE: Failure to erase ALL fault memories may cause "Update - Programming" (flashing) procedure to fail!

Select Diagnosis function 06 "End output".

The previous data in the control module is erased and the new data is being transferred to the module from the flash CD.

NOTE: Once "Update - Programming" function has been started, switching ignition OFF or disconnecting the diagnostic connector may completely destroy the TCM.

TIP: If, during the "Update - Programming", a fault message is displayed:

Fig 10: VAS Display - Fault Message

Confirm that VAS 5051 or VAS 5052 diagnostic tool power supply is adequate and that ALL appliances with high electromagnetic radiation (i.e. mobile phones are switched OFF.
