Update Programming To Eliminate Slight Tip-In Hesitation (GROUP 01, NO. 06-11)

UPDATE - PROGRAMMING (FLASHING)

TIP:  When performing the update programming 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 update programming procedure first. The following "Update - Programming (flashing) process may overwrite any "TUNED" ECM programming. A "TUNED" ECM is described as any ECM 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, prior to performing the Update - Programming" (flashing) procedure:

Your Dealership should place the vehicle owner on notice in writing, that their ECM was found to have been tuned, and that any damage caused by the tuning of the ECM (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 update programming, which will automatically wipe out the "Tuning" program, your Dealership should advise the owner of the above and get Owner's written consent (see attached Control Module Tuning form) to the update programming procedure.

TOOL REQUIREMENTS

VAS 5051 or VAS 5052 (with Base CD V.08.01.00 and the Brand CD V.08.69.01 or higher).

"Update - Programming" (flashing) CD W42SWU96229623. See "Required Parts and Tools.

TIP:  Additional copies of the "Update - Programming" CD (Literature Number W42SWU96229623) may be ordered from the Volkswagen Technical Literature Ordering Center at www.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

1. Battery MUST have minimum no-load charge of 12.5V (failure to maintain voltage during update process can lead to ECM failure) (it is advised to use an approved battery charger to maintain battery voltage).
2. VAS 5051: connected to vehicle and to 110V AC Power supply at all times during procedure.
3. VAS 5052: connected to vehicle with battery voltage requirements met.
4. Any appliances with high electromagnetic radiation (i.e. mobile phones) switched OFF.

When performing the update programming 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 update programming procedure first.

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

• Switch ignition ON.
• Switch VAS 5051/ VAS 5052 ON and insert update programming CD into CD drive as soon as start screen appears.
  1. Wait for CD-ROM light to stop flashing before proceeding.
     Fig 1: VAS Display - Start Screen

     

TIP:  You must return to the start screen before starting a new (flashing) session, otherwise the update programming CD will not be recognized by the tester.

• Select "Vehicle Self Diagnosis" mode.
• Select vehicle system "01-Engine electronics".
  • Program checks software level.

If software level of ECM MATCHES level indicated by update programming CD:

• "Update - Programming" (arrow) will not appear.
  Fig 2: VAS Display - Select Diagnosis Function

  

TIP:  The "Update - Programming" function is only available when the inserted update programming CD level and current vehicle ECM level are different.

If software level DOES NOT match the level indicated on update programming CD:

• "Update - Programming" (arrow) appears.
  Fig 3: VAS Display - Select Diagnosis Function

  
• If "Update Programming" does not appear and the ECM software level is an older level than the update programming CD level, select "06 - end output". Select vehicle system "01 - engine electronics". By reinitiating communication, "Update Programming" should now appear.

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

• Check and print ALL fault memories as follows:
  • Select backward arrow button
  • Choose "Gateway installation list"
    Fig 4: VAS Display - Select Vehicle System

    
  • Select the first Control Module for which "Malfunction" appears
  • Select "02 - "Interrogate fault memory"
  • Select "Print" and "Save result"
  • Answer "yes" to "erase old log?"
  • Press backward arrow button twice.
  • Repeat the preceding steps for all remaining Control Modules indicating "Malfunction". However, for the remaining Control Modules, answer "NO" when asked "erase old log"?

1. When all faults have been stored:
   • Select "Print" and then select "Self Diagnosis log"
2. Once ALL fault memories have been inspected:
   • Select vehicle system "01-Engine electronics".
     Fig 6: VAS Display - Select Vehicle System

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

"UPDATE - PROGRAMMING" (FLASHING), PERFORMING

After selecting "Update - Programming" function, new program version as listed below will install:

Fig 8: VAS Display - Update-Programming

By selecting the forward arrow button, the programming procedure begins.

Similar screen appears:

Fig 9: VAS Display - Programming In Progress

The previous data in the ECM is erased and the new data is being transferred to the module from the update programming CD.

• Approximate flashing time is 5 minutes.

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

• 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.
• The "Update - Programming" (flashing) process must then be started from the beginning using the "Repeat" button (arrow). DO NOT  use the "Cancel" button.

1. Once "Update - Programming" (flashing) is complete:
2. The tester requests you to switch the ignition OFF.
   Fig 11: VAS Display - Switch Off Ignition

   
   • Switch ignition OFF.
3. The tester requests you to switch the ignition ON.
   • Switch ignition ON when prompted.
4. After switching ignition ON, the ECM has been re-initialized, however, fault memories must now be erased.
5. Similar screen appears.

TIP:  ECM Part Number and new software level is displayed at (arrows).

• Select the "Print", then "Screen" button.
• Attach print to vehicle Repair Order.
• Select the forward arrow button to continue.

FAULT MEMORIES, ERASING AFTER "UPDATE - PROGRAMMING" (FLASHING)

Due to the CAN bus system, fault messages will be stored in various Control Modules during programming.

1. Erase ALL fault memories as follows:
   • Select the backward arrow button again.
     Fig 13: VAS Display - Erase Fault Memory

     
   • Choose "Gateway installation list"
     Fig 14: VAS Display - Select Vehicle System

     
   • Using the scroll bar, scroll down and select "19 - Gateway" as the first Control Module memory to erase.
   • Select "02 - interrogate fault memory"
   • Select backward arrow button.
   • Select "05 - erase fault memory"
   • Press backward arrow button twice.
   • Repeat the preceding steps.

1. Once fault memories have been erased:
   • Finish update of the ECM by selecting the backward arrow button.
2. Update programming CD can now be removed from VAS 5051 or VAS 5052 Diagnostic tool.
   • Attach prints to vehicle Repair Order.
   • Select "Go to" then select "Exit".

TIP:  It is not generally necessary to encode the ECM following the "Update - Programming" (flashing) procedure.

It is only necessary to set the readiness code if faults were present in the ECM before update programming. The update programming process does not create faults in the ECM or delete the readiness code.

• Use VAS 5051 or VAS 5052 to set readiness code.
