This premium front SAM control module unit is a direct OEM replacement designed for 2006–2013 Mercedes X164 GL450 and R350 models. Serving as the core signal control unit for vehicle front electrical systems, this refurbished and upgraded SAM module restores normal electrical system operation, fixes intermittent circuit failures, and matches factory programming parameters for plug-and-play vehicle compatibility.
Basic Product Details Built with industrial-grade waterproof circuit boards, high-temperature resistant electronic components, and reinforced anti-interference chip modules, this front SAM control unit features complete pre-programmed factory data to match original vehicle electrical protocols. Installed in the front vehicle electrical compartment, the module undertakes front light control, sensor signal reception, and circuit distribution management. It fully fits Mercedes X164 GL-Class and R-Class models produced from 2006 to 2013, with consistent wiring interfaces and mounting dimensions as stock units.
Core Upgrade Advantages This upgraded SAM control module optimizes the inherent defects of original factory units, including weak circuit anti-interference ability and easy component aging under long-term vibration and high temperature. Compared with stock modules that gradually lose signal accuracy and cause electrical system disorder after years of use, our upgraded unit adopts optimized chip logic and enhanced circuit protection technology for more stable signal transmission and longer service life. Strict factory-level testing and pre-programming eliminate complex coding and adaptation steps, enabling efficient replacement for repair shops and DIY vehicle owners.
Solves Common Owner Pain Points Original Mercedes X164 front SAM control modules have common aging and failure problems. Faulty stock units frequently cause intermittent headlight malfunction, abnormal turn signal flashing, front sensor signal loss, and vehicle electrical system random alarms. Severe failures will lead to startup failure, circuit short circuit protection, and unreadable vehicle fault data. Most owners face repeated electrical faults caused by aging SAM modules that cannot be completely repaired. This brand-new control module thoroughly resolves all front electrical system disorder issues.
Compatible OBD / VCDS Fault Codes Effectively fixes mainstream electrical fault codes triggered by damaged or aging front SAM control modules, including U0100, U0140, B1000, corresponding to module communication failure, body control signal loss, and electrical system module malfunction errors for Mercedes X164 chassis.
Logistics & Shipping Benefits We provide free global shipping for all orders. All front SAM control modules are stocked in overseas warehouses, with orders processed and shipped within 24 business hours after payment confirmation, ensuring fast electrical system maintenance and minimizing vehicle downtime.
Warranty & Installation Support
Every OUSIMY front SAM control module unit comes with a 2-year manufacturer warranty. Pre-programmed with original factory vehicle data, it features a fully plug-and-play design for friendly DIY installation. No additional professional coding, programming or circuit modification is required after installation.
