Improved ECM software resolves concerns related to:a. Adjustment to OBD catalytic converter diagnostic parameter strategy.b. Cold start secondary air strategy.c. EVAP strategy change to prevent system testing below 5° C (40° F).d. Adjustment to EVAP leak detection strategy.e. Adjustment to diagnostic strategy tolerances for changes to air intake volume over time.Production SolutionSoftware concern was identified after production was concluded.ServicePROCEDURE:Tool requirementsVAS 5051 or VAS 5052 (with Base CD V.11.00 and the Brand CD V.11.79.01 or higher).“Update - Programming” (flashing) CD W42010418TSWU.Tip:Additional copies of the “Update - Programming” CD (Literature Number W42010418TSWU) may be ordered from the Volkswagen Technical Literature Ordering Center at www.vw.resolve.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.Note:Non–observance 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.• Ensure the following vehicle requirements are met:? Connect vehicle to a powered Volkswagen approved Midtronics/InCharge 940 (INC-940) tester/charger? Battery MUST have minimum no-load charge of 12.5V? Turn off the radio and all other accessories, and when necessary, switch running lights off? Turn off any appliances with high electromagnetic radiation (i.e. mobile phones)Engine Control Module Update - Programming (Flashing) using CDTip: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/TCM programming. A “TUNED” ECM/TCM is described as any ECM/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/TCM, prior to performing the “Update - Programming” (flashing) procedure:• Your Dealership should place the vehicle owner on notice in writing, that their ECM/TCM was found to have been tuned, and that any damage caused by the tuning of the ECM/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 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.Tip:Before update programming, delete the fault memory in the ECM. Update programming is not possible when an EEPROM fault is active.Reprogram ECM with CD - Part number W42010418TSWU.• 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.Tip:Once update programming is complete, switch ignition OFF for 30 seconds.After a minimum of 30 seconds, switch ignition ON.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.ModelEngineOld Software Part No.Old Software VersionNew Software Part No.New Software Version (or higher)New Beetle, New Beetle Convertible1.8L T06A997012All06A997012977706A997012A06A997012A977606A997012B06A997012B977506A997012C06A997012C977806A906032QA06A997012977706A906032PR06A997012A977606A906032PT06A997012B977506A906032PS06A997012C977806A906032EM06A906032EM977406A906032FD06A906032FD9773Tip:For vehicle with cold start misfire DTCs P0300-P0304, also add approved fuel additive to fuel tank before returning vehicle to customer. See technical bulletin(NNN) NNN-NNNNIf vehicle returns after software update and consumption of entire fuel tank with fuel additive with cold start misfire DTCs P0300-P0304, select the "Technical Assistance" tab in ElsaWeb and follow the instructions to obtain a 6 digit pin.WarrantyTo determine if this procedure is covered under Warranty, always refer to the Warranty Policies and Procedures Manual *Model(s)Year(s)Eng.
