RVU Update Programming to Eliminate Poor Throttle Response (OJ)
Tip:
Technical Bulletin Expiration Date: August 24, 2008.
Note:
BEFORE performing this update:
^ Inform customer the update addresses poor throttle response concerns they may have with the vehicle.
^ Inform the customer that, after the update, the gear display feature in the MFI while in Drive "D" (e.g. 1, 2, 3, 4, 5, 6) will no longer appear. This update is not reversible and the feature cannot be turned back on.
^ DO NOT perform Update Programming if the customer wants to keep the gear display feature. Code "Customer Refused Repairs" as per claiming instructions in this bulletin.
Technical Background
Updated ECM and TCM software that addresses:
^ Poor throttle response
Engine and Transmission Control Modules Affected:
Production Solution
Software concern was identified after production was concluded.
Service
Requirements:
Vehicle must meet ALL of the following criteria:
1. VIN must show (OJ) code open in ElsaWeb on the day of repair.
2. Vehicle must be within the Limited New Vehicle Warranty.
3. Update must be performed prior to expiration date listed in this technical bulletin.
Tip:
Procedure must also be performed on applicable vehicles in dealer inventory.
Tip:
Update programming procedure has been revised for vehicles equipped with the higher speed diagnostic CANnostic CAN-bus.
PROCEDURE:
Update - Programming (Flashing)
Engine and Transmission Control Module Update - Programming (Flashing) Using Software Version Management (SVM)
Vehicle requirements
MUST have minimum no-load charge of 12.5V (failure to maintain voltage during update process can lead to ECM failure) (use a Volkswagen approved Midtronics/InCharge 940 (INC-940) tester/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.
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.
Note:
Nonobservance of the following points may lead to ECM failure!
^ VAS 5051 or VAS 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 update programming procedure.
^ Any appliances with high electromagnetic radiation (i.e. mobile phones) must be switched OFF.
Tip:
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. For further update instructions and troubleshooting, refer to SVM Technical Bulletin Instance 2014603, in ElsaWeb.
^ Update the Engine Control Module using the Software Version Management (SVM) and the SVM Unit code as listed in the table shown.
Note:
It may be possible to set a communication fault in the parking brake module that will not be erased by Compiling Services. If this occurs, remove the ignition key for one minute and then cycle the key on and clear fault.
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 Control Module Tuning form) to the update programming procedure.
