Service bulletins for the 2012 Volkswagen Routan

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.

TT131301a2023-07-10. Service bulletin. POWER TRAIN; ENGINE AND ENGINE COOLING. When servicing the timing chain sprocket or removing the vibration damper, be aware that one bolt holds both the vibration damper (harmonic balancer) and the crankshaft timing chain sprocket to the crankshaft. Once the damper is removed, the crankshaft should not be rotated unless special tool spacer T10368 has been installed. The crankshaft timing chain sprocket and spur gear drive on the crankshaft have a coupling that must be seated correctly during assembly. Failure to install special tool spacer T10368 before rotating engine will cause the engine to skip time and bend valves.

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).
