Throttle Valve Repair Kit — BMW B47 / B57 / B37 Diesel | OEM 13548512452 / A2C80221200
Fix Throttle Valve Failure on Your BMW B47, B57, or B37 Diesel — Repair Kit with Replacement Gears.
The throttle valve on BMW B47, B57, B37, and B47B/B57S diesel engines uses a plastic half-moon gear actuator that wears and strips — causing the throttle flap to stop responding, fault codes, and limp mode. This repair kit replaces the broken gear and all wear components, restoring full throttle valve function without replacing the entire throttle body.
Why Repair vs. Replace
- Targeted Fix: The plastic gear is the failure point — the throttle body housing and motor are typically intact.
- Restores Throttle Response: New gear restores correct actuator movement and throttle position sensing.
- Major Savings: New BMW throttle bodies cost $200–$400+. This kit costs $38.
Vehicle Compatibility
BMW models with B37B, B47D, B47B, or B57S diesel engines
