B. V011231 dated October 24, 2012 to add additional text about readiness codes on UDS vehicles. TDI Clean Diesel I/M (Inspection Maintenance) Testing Issues due to Readiness Not Set DTCs were recently erased from the vehicle’s engine control module (ECM). A Volkswagen TDI clean diesel is not ready for I/M (Inspection Maintenance) testing due to readiness codes not being fully set. Tip: This does not indicate any technical problems with the vehicle, only that more driving may be necessary to set full OBD readiness. Certain environmental conditions and customer driver profiles may extend the drive time required to fully set readiness on TDI clean diesel vehicles. Fully setting the DPF monitoring function requires a cycle of building soot and burning the soot off during a regeneration process. Tip: If possible, advise customer not to service vehicle directly before I/M inspection. If the readiness bits are reset, this can create a condition where extensive driving is required prior to setting full readiness. Page 1 of 9 © 2015 Volkswagen Group of America, Inc.

Technical Bulletin Technical Background Some readiness codes on TDI clean diesel vehicles require special driving conditions to be set. If DTCs have been recently erased from the vehicle’s ECM, it may take additional driving under different conditions to fully set OBD readiness parameters. MVB 89 (on non-UDS protocol ECM’s) will store correct data concerning OBD readiness. Figure 1 illustrates how to manually read OBD readiness codes. Figure 1. An example of a possible MVB 89 reading. Actual values will depend on vehicle tested and OBD readiness status. Tip: To check readiness code status, verify ODIS is at the latest software level and utilize the following: From the control module list view, right click on the ECM and select Vehicle OBD. Then select OBD customer service. Left click on Mode 01: “Check current diagnostic data. PID 01”. Click on each individual selection to verify status.

Technical Bulletin Additional Information: Interpreting Bit Values: MVB89 is displayed as an 8-bit value. Depending on which diagnostic tester is used, the measurement value may be displayed as follows: „1010 0100“. All positions in the measurement value are described in bits, where Bit0 is the rightmost position and Bit7 is the leftmost position.

Technical Bulletin Production Solution No Production Solution required. Service 1. To check the correct status of OBD readiness, refer to MVB 89 and the supplemental information in the Technical Background section (applies to non-UDS protocol vehicles). For ECMs with UDS protocol, readiness status can be obtained by reading the Mode 1 – Mode 10 data within the OBD section of the scan tool. 2. If any OBD system indicates incomplete monitoring (“1” shown in Byte 4) with no DTCs stored in the ECM, no repair is necessary. Tip: There is no need to repair any vehicle system due to readiness not being set. Repair work is required only if there is a relevant DTC stored within the ECM and the MIL is illuminated. Ignore pending DTCs. Tip: Do not reset the ECM unless a DTC is saved in memory and the MIL is illuminated. Ignore pending DTCs. Resetting the ECM will erase the readiness codes and additional driving will be required to set the readiness codes. 3. The vehicle requires additional driving to complete the OBD readiness checks. Drive the vehicle until all required monitoring systems indicate complete readiness before attempting emissions testing. Do not send a customer to I/M testing until the readiness meets the minimum state requirements. 4. Contact the VW Technical Helpline (TAC) if there are difficulties setting readiness on a TDI clean diesel vehicle. Procedure: Required conditions for running this procedure: Switch OFF accessories (ex. Heated seats, rear defroster, climate control, lights, etc.). No fault entries recorded in the Engine Control Module (ECM). Driving profile requires approximately 60-90 minutes. General procedure in order to achieve “Readiness” (diagnostic checks complete) The engine should be running (leave ignition key “on) during the entire procedure so that the driving profile is not extended unnecessarily. Some of the bits described in the table may be set by driving the vehicle a certain way. In this case, the corresponding test procedure steps can be skipped.

Technical Bulletin Procedure for Diesel Particulate Filter (DPF) Regeneration Only one DPF regeneration is necessary per driving cycle. This means, if points 1-7 need to be carried out, only one DPF regeneration is required. In order to carry out regeneration: Start adaptation channel 13 (DPF service regeneration) with security access. The DPF light switches ON and stays ON for the entire time during regeneration. If the light switches OFF, then the regeneration process is completed. During regeneration, the vehicle needs to be driven at constant speed (50-70 mph or 80-120 km/h), preferably using cruise control over a stretch of highway or country road. Periods of vehicle acceleration or coasting should be avoided. Note: Obey all local and state traffic laws. Description of Table 2 The column “NO.” shows an optimal sequence for conducting the readiness vehicle profile split into individual “readiness categories”. The “Number” stands for a particular “readiness category”, and the “Letter” stands for a “subcategory” which needs to be set in order to test the “readiness category”. The column “MVB 89 Ok = 0” describes the “readiness category”. This bit = 0 when this category has achieved readiness. The “subcategories” belonging to this “readiness category” no longer need to be carried out. The column “MVB 86 Ok = 1” describes the readiness “subcategory”. This bit = 1 after the “category” has been tested. The “subcategories” no longer need to be tested when the “readiness category” bit for the particular “subcategory” has already been set. The column “procedure” describes the required vehicle profile which is necessary to set the bits in the “readiness category” or in the “subcategory.
