Throttle Valve Repair Kit – BMW B47 / B57 / B37 Diesel | OEM 13548512452 A2C80221200

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.

Fits OEM #13548512452.
