Mercedes-Benz R320 CDI Problems

The transmission drive selector module may fail resulting in the loss of gear selection capability. This condition can leave the vehicle stranded, and will require replacement of the drive selector module.

The engine may stall or not start due to a failed crankshaft position sensor. Replacing the failed sensor should correct this issue.

The HVAC blower motor may fail. This is commonly caused by water entry through the cabin air filter areas during heavy rain or snow. Failed blower motors should be replaced. Our technicians tell us there is no special fix for this issue at this time.
