Mercedes-Benz W210 Front SAM Module 0005401050 - Used Original Parts

Diagnosis and Common Symptoms

The Front SAM (Signal Acquisition Module) on the W210 chassis governs headlight operation, front indicators, horn function, wiper control, and communicates directly with the instrument cluster over the CAN bus. A failing unit typically presents as intermittent headlight flicker, non-functioning low or high beams on one side, horn that sounds randomly or not at all, wipers that fail to park correctly or stop responding, and warning messages on the dashboard such as "Check Lighting" or unexplained bulb-failure alerts even when bulbs are good. Corroded relay contacts inside the SAM housing are a common root cause, along with cracked solder joints from years of engine bay heat cycling. In advanced cases, the module drops off the CAN network entirely, triggering multiple unrelated fault codes during diagnostic scans because downstream systems lose their data feed.

Introduction

This is a Genuine Used Mercedes-Benz Front SAM Module, part number 0005401050, pulled from a running W210 donor vehicle. Every unit is bench Tested for relay switching, CAN communication, and output signal integrity before listing, so you are not gambling on a random pull. Sourcing a Genuine used module avoids the compatibility headaches that come with aftermarket clones, which often fail to communicate properly on Mercedes' CAN architecture. If your existing SAM is showing electrical faults, this is a direct, ready-to-fit replacement.
