V011231 20235912019-04-08. Service bulletin. ENGINE AND ENGINE COOLING; EQUIPMENT ADAPTIVE/MOBILITY. Technical Bulletin (TDI Clean Diesel I/M (Inspection Maintenance) Testing Issues due to Readiness Not Set): 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. This document illustrates how to manually read OBD readiness codes.
V211302 20240612019-04-08. Service bulletin. ENGINE AND ENGINE COOLING. Technical Bulletin (Rattling Noises from Engine Compartment Area or Exhaust System): Customers may complain of a rattling noise from engine or exhaust area while accelerating from 1800-3000 RPM. In order to complete proper diagnosis and ensure that the noise is coming from the turbocharger use the procedure in this document.
V191303 20225492019-04-08. Service bulletin. ENGINE AND ENGINE COOLING. Technical Bulletin (Electric Coolant Fans Continue to Run after Ignition is Switched OFF): This document informs it is considered normal operation for the electric coolant fans to continue to run for up to 15 minutes after the ignition is switched off in gasoline engine applications, and up to 16 minutes in diesel engine applications.
V171303 20178132019-04-08. Service bulletin. ENGINE AND ENGINE COOLING. Technical Bulletin (Oil Consumption Measurement): Customers have stated oil consumption is higher than the Volkswagen oil consumption standard of up to 0.5 quarts per 600 miles, or 0.5 liters per 1000 km. This document informs how to test the oil consumption rate
V011333 20348982019-04-08. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. Technical Bulletin (Exhaust Gas Recirculation Flow Insufficient issues): This document informs that high soot loads prior to regeneration can cause possible restrictions in the EGR filter. The production solution to this issue is New software being implemented in current production.
TT 26-13-032019-04-08. Service bulletin. FUEL SYSTEM, DIESEL; ENGINE. Tech Tips (CBEA, CJAA, CKRA engine codes DPF replacement and/or DTCS P2413, P2463): This document informs of the use of aftermarket air filters such as cotton bed steel mesh or cone style, can cause the MAF sensor to not read accurately, affecting vehicle performance and critical monitoring functions for the diesel particulate filter. This can also result in premature DPF failure. Only use factory air filters. The use of aftermarket air filters is not supported as the system was designed and calibrated to work with factory air filters.
V211301 20254642019-04-08. Service bulletin. ENGINE AND ENGINE COOLING; ENGINE. Technical Bulletin (Frozen Charge Air Cooler ? Engine Will Not Start): Engines will not start after standing in cold weather below 0°C (32°F), MIL may be illuminated with various induction and/or boost system faults stored in ECM. Moisture from the intake air condenses and collects in the charge air cooler. At cold temperatures this moisture can freeze causing blockage of the intake air system. This document informs how to Install a revised charge air cooler kit P/N 1K0 198 803B to avoid the formation of this moisture in the boost system.
V011330 20348982019-04-08. Service bulletin. ELECTRICAL SYSTEM; ENGINE. Technical Bulletin (Exhaust Gas Recirculation Flow Insufficient Stored in ECM Fault Memory, Could be Accompanied with Fault P2463 DPF Soot Accumulation): High soot loads prior to regeneration can cause possible restrictions in the EGR filter. This production solution to this issue is new software implemented in current production.
TT 24-07-1032019-04-08. Service bulletin. ENGINE. Tech Tips (Vehicles with 2.5L Engine - Fault Code P2279 (Leaking Air in Intake System) Diagnostic Tip): When diagnosing fault code P2279-Leaking Air in Intake System, be sure to check the cam timing first. This document informs how to check the cam timing
VSS-17-122019-04-08. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL. Volkswagen of America is requesting your cooperation in supplying us with technical information related to the repair process for vehicles on which the TDI Generation I, II, and III 2.0L emissions modification is being performed ?Campaigns 23U3?. Volkswagen will use this information to ensure prompt analysis and resolution of any emerging concerns.
TT 2614022019-04-08. Service bulletin. ENGINE AND ENGINE COOLING. Update procedure to reset oxygen sensor adaptations, as a result of erratic test plan function.

Customer Only (Retail Sold) USA ONLY - The Environmental Protection Agency and California Air Resources Board have determined that Volkswagen vehicles equipped with a 2.0L 4-cylinder TDI engine do not comply with applicable emissions regulations. The emissions control systems on the vehicles will not control emissions under off-cycle conditions as effectively as during the federal test procedure. The extent of the emissions increase under off-cycle conditions depends upon how the vehicles are driven. Revision Summary Updated work instructions.
TT 0117052019-04-08. Service bulletin. ELECTRICAL SYSTEM; ENGINE. Coding information for replacement ECM to address specific fault setting after the install.
