🔧 Item Description
Genuine Mercedes-Benz OEM Rear SAM Control Module.
Fits R230 SL-Class models for the 2003–2012 production range.

✔️ Diagnostic Check: Scanned with professional diagnostic tools; verified 100% CAN-bus communication and zero internal microprocessor faults.
✔️ Electrical: All multi-pin ports and harness connectors are clean, bright, and free of bent pins.
🧼 Condition & Inspection

⚠️ Water Damage Inspection: Rigorously inspected for the most common R230 failure: zero moisture damage. Rear SAMs are frequently ruined by trunk seal leaks; this unit has a pristine, dry circuit board with no signs of corrosion.
Housing: The plastic mounting frame and locking tabs are fully intact.
Fuses/Relays: Comes populated with a set of tested relays. Note: Please verify your specific fuse map to match your vehicle's option codes.
