Mercedes-Benz W209 Right Rear Tail Lamp Assembly - Used Original Parts

Diagnosis and Common Symptoms

From a technician's perspective, the W209 tail lamp assembly is prone to internal circuit board failure, not just simple bulb burnout. The primary symptom is a "Lamp Defective" warning on the instrument cluster, often accompanied by a fast-blinking turn signal. A diagnostic scan with STAR/XENTRY will typically reveal fault codes related to open circuits or implausible signals for the right rear exterior lighting, such as "9051: The component E4e2 (Right stop lamp) has Short circuit to positive" or "9059: The component E4e4 (Right turn signal lamp) has an open circuit."

Visually, you will observe one or more functions failing—the brake light, turn signal, or tail light may be inoperative or flicker intermittently. This is a classic sign that the bulb carrier's printed circuit board has developed a fault, a common wear item on the CLK-Class. Replacing the entire assembly with a tested, genuine unit is the most reliable and permanent repair.
