Technical Service Bulletin
Check service history to see if the improved “ B” suffix V157 Intake Flap motor has already been
installed previously; if yes, only replace the potentiometer seals as described below.
The fault entry is made because a linkage of the intake manifold flap adjustment sticks.
This is caused by deformed oil seal behind the
potentiometers.

Figure 1. Deformed oil seal behind potentiometer.
