Service bulletins for the 2010 Volkswagen Jetta

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

TT3214012023-07-05. Service bulletin. POWER TRAIN. Incorrect torque converter or flywheel/flexplate installation can result in transmission damage. When installing an engine, flywheel or transmission, please follow the installation procedures outlined in ELSA. For the flywheel/flexplate, please be certain the correct shim is installed between it and the crankshaft (reference VWIQ120). When installing a torque converter, press the torque converter hub through the seal as far as the first stop. Turn the torque converter while pushing toward the transmission using light force, until the cut outs in the torque converter hub lock into the pump wheel plate. The torque converter slides in. The torque converter is installed correctly if it is easy to turn by hand and if it fits evenly in the transmission bell housing. Additionally, it should spin freely when the transmission bell housing bolts are torqued to the engine block, prior to installation of the flywheel to converter bolts (reference VWIQ121).
TT2713012023-07-05. Service bulletin. ELECTRICAL SYSTEM. When diagnosing a generator charging concern, it is recommended to verify operation of the one way clutch located in the generator pulley (if equipped) before replacing generator assembly. To check the one way clutch, remove the belt from the generator pulley and use a trim removal tool to hold fan blades inside generator, as shown below. When attempting to turn pulley by hand with fan blades held, pulley should spin freely in only one direction. If pulley spins freely in both directions, the one way clutch has failed and should be replaced before continuing diagnosis.
TT2614022023-07-05. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM); ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. Disconnect both O2 sensors (front and rear), start engine and let idle. Check MVB's 41/4 and 136/4 and verify have both changed from a 1 to a 0 (you may have to drive the car 4 miles to get them to reset to 0). Also a key cycle may be required for values to reset. This forces the ECM to re-learn the O2 sensor adaptation. Once MVB 41/4 and 136/4 read 0, re-connect the O2 sensors, road test and recheck for faults.
TT2613032023-07-05. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. 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.
TT2611012023-07-05. Service bulletin. FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING. 2012-2013 Passat does not have measured value block numbers. Check values ?Particle filter, kilometers since last regeneration?, ?Particle filter, oil ash volume?, ?Particle filter, soot mass calculated?, and ?Particle filter, soot mass measured? instead.
TT2413032023-07-05. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM). When diagnosing a vehicle concern, and fault P130A ?Hide Cylinder? is found in the Engine Control Module (ECM), be aware that Engine Control Module (ECM) fault P130A ?Hide Cylinder? indicates a cylinder shut down and does not require diagnosis.
TT2411022023-07-05. Service bulletin. ENGINE AND ENGINE COOLING; ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM). For concerns of Fault Code P117A ?Bank 1, correction Lambda middle reached adjustment limit? stored in the ECM, check that the O2 sensors have not been installed or connected improperly.
TT24071032023-07-05. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM). When diagnosing fault code P2279-Leaking Air in Intake System, be sure to check the cam timing first.
TT2314012023-07-05. Service bulletin. FUEL SYSTEM, GASOLINE. When replacing or adapting fuel injectors, if there is no Guided Functions Test Plan, utilize the following :UDS vehicles: Go to Guided Functions / Adapting Injector Quantity Adjustment correct values (IMA-IVA).
TT2310022023-07-05. Service bulletin. FUEL SYSTEM, GASOLINE. When replacing fuel system components on the Common Rail TDI engine (including the fuel filter), the fuel system must be primed.
TT2113012023-07-05. Service bulletin. PARKING BRAKE. If mechanical damage is found to the turbocharger (e.g. damaged compression wheel, loose or broken shaft), it is not enough to just replace the turbocharger.
TT2110012023-07-05. Service bulletin. ENGINE. When diagnosis on the above engine leads to the testing of the N75, please refer to the picture below. The diagram shows which vacuum ports on the N75 valve should hold vacuum and which ones should not.
TB5514042023-06-26. Service bulletin. EXTERIOR LIGHTING. Corrosion on the Rear Lid around License Plate Lights
TB5114022023-06-26. Service bulletin. STRUCTURE. Rocker Panel - Front Fender ? Corrosion
TB5014032023-06-26. Service bulletin. WHEELS; STRUCTURE. Surface corrosion or corrosion perforation can occur on various locations around the front wheel arch.
TB3713022023-06-26. Service bulletin. POWER TRAIN. This bulletin provides a procedure to determine ?repair? versus ?replacement? of an automatic transmission. This procedure is to be used ?After? the transmission has been removed from the vehicle.
TB3713012023-06-26. Service bulletin. POWER TRAIN. Automatic Transmission Fluid Requirements
TT9714022023-06-13. Service bulletin. ELECTRICAL SYSTEM. The DLC is intended for use with diagnostic scan tools and by emissions testing stations. However, aftermarket devices (i.e., drive data recorders) that connect to the DLC have now become available.
TT9614022023-06-13. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. When replacing the complete vehicle lock set (all vehicle keys and lock cylinders) for any reason, be aware that the ?Adapt keys? test plan will not allow the new keys to adapt to the vehicle. Instead, perform the test plan for ?New identity?. During this test plan, make the appropriate selection to indicate only the lock set has been replaced, as shown below in figures 1 and 2.
TT9114032023-06-13. Service bulletin. EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.; BACK OVER PREVENTION:SOFTWARE. When replacing the radio on a 2010 ? 2011 vehicle equipped with a Premium 8 (RCD 510) radio with part number ending in the suffix ?AC? (1K0 035 180 AC), if the replacement part has a suffix ?AF?, make sure that online coding is performed. DO NOT PERFORM ANY SOFTWARE UPDATE OF THE ?AF? RADIO USING AN SD CARD OR ANY OTHER MEANS. No software updates are available for ?AF? suffix radios. Any attempt to update the software using an SD card or other means can result in permanent damage to the radio.
TT9113062023-06-13. Service bulletin. ELECTRICAL SYSTEM. If the radio is switching to the Bluetooth audio selection whenever a paired phone makes any sound, such as typing or an incoming email or text message, check the BT-Audio Autoplay setting in the Media Setup menu as shown below. If BT-Audio Autoplay is on (checked), switch selection off and retest for concern. If radio software is 0016 or 0007, radio may require software update as per TB 91-13-05 (2031136) to allow BT-Audio Autoplay to switch off.
TT9113042023-06-13. Service bulletin. EQUIPMENT. When replacing a radio navigation unit, inspect the security labels on both the new and replacement units for damage. If damage is found to a label on either unit, be sure to note this on the repair order along with the reason the radio is being replaced.
