Product Title

Mercedes Benz W230 SL350 Front Left SAM Fuse Box Control Module A230 545 40 32 - Used Original Part

Diagnosis and Common Symptoms

In the workshop, we frequently see the W230 SL-Class present with erratic electrical behavior stemming from the Front Left SAM (Signal Acquisition and Actuation Module). Due to its location, this module is highly susceptible to moisture ingress and corrosion. Common symptoms of a failing A230 545 40 32 unit include intermittent failure of the low-beam or high-beam headlights, windshield wipers that refuse to park or activate, and localized battery drain issues. You may encounter dashboard warnings such as "Display Defective" or find that the horn and turn signals are non-functional. Diagnostic scans often reveal communication faults (CAN bus errors) or internal hardware failure codes such as B1000. Replacing a compromised unit with a verified Genuine part is essential for restoring the vehicle's electrical integrity.

Introduction

As a senior technician at M.S. Motor, I prioritize reliability over the high cost of brand-new modules or the poor quality of aftermarket alternatives. This Genuine Used Front Left SAM has been salvaged from a donor vehicle and subjected to rigorous bench testing to ensure all internal relays and circuits are fully operational. By choosing a Genuine Mercedes-Benz component, you ensure the hardware architecture is perfectly matched to your SL350's communication network. This part has been inspected for the typical signs of water damage often found in used R230 components, ensuring you receive a clean, functional module ready for installation.

Frequently Asked Questions

Q: What symptoms indicate failure? A: Failure usually manifests as "ghost" electrical issues. This includes headlights staying on when the car is off, wipers failing to operate, or the vehicle failing to recognize signals from the steering column switch. If you see a "Check Light" error for a bulb that is actually functional, the SAM is the primary suspect.

Q: Does this require coding? A: Yes. Because the SAM module manages various vehicle-specific features, it will require SCN coding or variant coding using a Star Diagnosis (DAS/XENTRY) system to match your vehicle’s specific equipment string (e.g., Xenon vs. Halogen lighting).

Q: Is this original? A: Yes, this is a Genuine Mercedes-Benz factory-fitted component. We do not stock aftermarket SAM modules as they often lack the build quality required for the complex R230 electrical architecture.
