W251 320CDI ISM / EHS
Here's what happened. Go to a workshop without changing gear. It was no longer possible to shift gears.
Okay let it be towed home. Error read ISM defective.
Removed, sent away, got programmed back.
Built-in. Communication with selector lever module faulty, okay used after bought.
Installed today, see picture.
Can't be taught. Cause it gets no messages from the Selector lever... Passenger footwell dry.
