Seat Bolster Servo Gear — BMW
Fix Your BMW Seat Bolster Adjustment — Replace the Broken Servo Gear, Not the Whole Motor.
The plastic drive gear inside the BMW seat bolster (popliteal support) servo motor is the most common failure point. When it strips, the seat bolster stops adjusting and the motor runs but moves nothing. This replacement gear restores full seat bolster function at a fraction of motor replacement cost.
Why Replace Just the Gear
- Targeted Fix: The gear is almost always the only failed component — the motor itself is usually fine.
- Restores Seat Comfort: Full bolster adjustment returns with a new gear.
- Fraction of Motor Cost: New BMW seat motors cost $150–$300+. This gear does the job for $19.
