Service bulletins for the 2004 Volkswagen Passat

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.

After replacing a Bosch 5.7 ABS module, refer to the table below to determine correct module coding value based on vehicle PR codes. Listed login code must be entered under Access/authorization before coding is attempted. After completing coding, G85 steering angle sensor basic settings must be performed before cycling key. To perform G85 basic settings manually in Vehicle self-diagnosis (VAS PC) or Control Module OBD (ODIS), start by entering access/authorization code 40168. After code is accepted, turn steering wheel 1 turn left and back to center, one turn right, and then center steering wheel. Select basic settings and enter group 1.

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).

TT8710052023-06-13. Service bulletin. SERVICE BRAKES, HYDRAULIC; ELECTRICAL SYSTEM. For concerns of no or intermittent A/C operation where pressure diagnosis does not lead to a cause, be sure to check the N25 A/C clutch coil. The fan control module may send a brief voltage signal to the clutch and then shut it off due to an open or high resistance in the coil circuit. The coil resistance should be between 3.5 and 4.5 ohms. If the reading is high or low when checked at the fan module, be sure to double check right at the coil to rule out any wiring concerns. Additionally, check ground circuit integrity for the clutch coil.
