Mercedes REMAN Warm-Up Regulator BOSCH 0438140148

 Mercedes REMAN warm-up regulator BOSCH 0438140148 is designed to help restore proper cold-start fuel control in compatible 380,450, and 500 Mercedes-Benz models. As a key part of the fuel injection system, the regulator adjusts the control pressure during engine warm-up, supporting smoother starts and more stable running when the engine is cold. Over time, a worn regulator can cause rough idle, hard starting, hesitation, or poor drivability. This remanufactured unit offers a practical replacement option for drivers who want dependable performance without compromising on fit or function.
