TT4411012023-07-05. Service bulletin. ELECTRICAL SYSTEM. If the battery has a low state of charge or is disconnected, fault code 02757 ?adapting tire pressures? may set in address 03 ? Brake Electronics. The GFF test plan for this fault may prove inconclusive and the fault may not clear, even after performing TPMS reset using the button in glove box or through the MFI.
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.
TT2613012023-07-05. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. When diagnosing ECM fault P2413 ?Exhaust Gas Recirculation System Performance?, pressure test turbo hoses for leaks and repair as necessary.
