Wiper motor link arm adjustment

A revised setting of the front wiper motor link arm has been introduced on production from VIN 854-166000, 855-70000. When a wiper motor is replaced on any 850 the new motor should be set according to the following instructions, using the template.

The revised setting parks the motor armature in the optimum position minimizing carbon build up and extending motor life.
