A2115452132 Mercedes W211 S211 SAM Passenger Side Module – OEM Used & Tested

Description

This Mercedes SAM passenger side module is a genuine OEM electronic component for Mercedes-Benz W211 and S211 E-Class vehicles. Primary OEM number A2115452132. It is designed to act as the signal acquisition and actuation module for the passenger side of the vehicle, switching and monitoring several electrical consumers through its internal relays and drivers.

Its job is to receive signals from switches and control units, then power and control functions such as exterior lighting, wipers, horn and other comfort and body electronics on its side of the car. It also exchanges data with the rest of the vehicle network over the CAN bus. A properly working SAM module supports reliable lighting and body functions and correct operation of the vehicle electrical system.

Common signs of a faulty unit include lights that stop working or work randomly, wipers that do not respond, a horn or comfort function that fails, warning messages on the instrument cluster, a battery that drains overnight, or fault codes stored in the control units. When the module has a damaged relay or an internal fault, the electrical system may behave unpredictably and several functions can fail at the same time. Diagnosis by a qualified workshop is advised before replacing the module.

This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number A2115452132 before ordering. Professional installation is recommended, and diagnostic checks, coding or SCN adaptation with a Mercedes compatible tool may be needed where applicable.
