SERVICE

REQUIREMENTS

Vehicle must meet ALL of the following criteria.

  1. Procedure is valid only for vehicles that show the OE code in the OTIS View Campaign inquiry screen on the day of repair.
  2. Vehicle must be within the Limited New Vehicle Warranty.
  3. 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

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:

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.

  • 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".
    Fig 5: VAS Display - Select Diagnosis Function
    G04580035
  • Select Diagnosis function 00 "Collection services".
  • Select "Check DTC memory - complete system". which will interrogate all fault memories.
  • Erase ALL fault memories.

With all fault memories erased:

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

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:
