Update Programming for ECM part number beginning with "07K"
Updated ECM software resolving various powertrain concerns.
Technical Background
Note:
Prior to performing Update Programming, please inform the customer that this software update addresses all of the concerns listed above. Once the Control Module programming is complete, the module cannot be returned to its original state. Please inform the customer that their concern addressed by this technical bulletin will not be resolved without this software update. Do not perform Update Programming if the customer does not want the Update Programming installed in their vehicle.
Updated ECM software that addresses:
^ Speed regulation of the camshaft adjuster.
^ Incorrect algorithm used in ECM software.
^ Exhaust popping noise is an exhaust resonance that becomes more audible under certain RPM and load ranges during the catalyst heating phase of cold start.
^ Engine Control Modules Affected:
Production Solution
Update software addressed in production as of:
Service
PROCEDURE:
Tip:
Update programming procedure has been revised for vehicles equipped with the higher speed diagnostic CAN bus.
Note:
The programming for this procedure is designed to work with the diagnostic CAN-BUS. The New Beetle and New Beetle Convertible is an older platform which does not support the use of CAN-BUS, instead, the New Beetle and New Beetle Convertible relies on the K-line for communication. BEFORE attempting to flash these vehicles, remove Pin 6 from the Data Link Connector (T-16) using special tool VAS 1978A. After the programming procedure has completed, re-install Pin 6 into the Data Link Connector.
Engine Control Module Update - Programming (Flashing)
Tip:
Update programming procedure has been revised for vehicles equipped with the higher speed diagnostic CAN bus.
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.
Tool requirements:
^ VAS 5051 or VAS 5052 (with Base CD V.11.00 and the Brand CD V.11.79.01 or higher).
^ "Update - Programming" (flashing) CD W420607A5SWU.
Tip:
Additional copies of the "Update - Programming" CD (Literature Number W420607A5SWU) may be ordered from the Volkswagen Technical Literature Ordering Center at --> http://www.vw.resolve.com/, or by calling 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:
^ MUST have minimum no-load charge of 12.5V (failure to maintain voltage during update process can lead to ECM failure) (use an approved battery charger INC940 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:
Before update programming, delete the fault memory in the ECM and TCM. Update programming is not possible when an EEPROM fault is active.
Reprogram ECM and TCM with CD - Part number W420607A5SWU.
Note:
TCM reprogramming is only necessary if the feature for update programming is available.
Insert the programming CD into the VAS 5051 / 5052, and access the ECM.
Tip:
If the update programming button does not appear, the latest version has already been installed to the level below.
^ Programming starts by pressing the "Update Programming" button and following the on screen prompts.
Note:
Once update programming begins, on NO occasion should the Cancel button be selected.
^ Press the "Update Programming" button.
^ Once ECM update has been performed, access TCM and perform "Update Programming" if the VAS 5051 / 5052 shows the "Update Programming" feature.
Tip:
Once update programming is complete, it is recommended to use 1001- Compiling Services prompt to clear faults stored in various control modules.
^ Reset readiness code.
