Mercedes-Benz W203 Kompressor M111 Alternator A0111547202 - Used Original Parts

Quick Answer

An alternator is the right fix on a W203 C200 Kompressor when the battery warning light comes on, or the battery keeps going flat even though the battery itself tests healthy. A tested used original unit suits the Malaysian owner who wants a Genuine Mercedes-Benz charging part at a lower price than new, with the warranty stated in the quote. Brand-new original and brand-new China-made units are also available for owners who prefer them.

Diagnosis and Common Symptoms

On the W203 C200 Kompressor with the M111 engine, the alternator keeps the battery charged and powers the electrical system while the engine runs. When it weakens, the car usually shows one or more of these symptoms:

• Battery warning light on the instrument cluster, either steady or flickering at idle.
• Headlights and interior lights dimming at idle and brightening when revs rise.
• A battery that goes flat after short trips, or a car that needs a jump start even though the battery is fairly new.
• Whining, grinding or rumbling from the front of the engine, often a sign of a worn alternator bearing.
• Slow electric windows, weak blower fan or a sluggish central locking, caused by low system voltage.
• Low-voltage or generator-related fault entries stored in the control units after repeated flat-battery events.

Before replacing the alternator, confirm the battery is healthy and check the voltage at the battery terminals with the engine running. A healthy charging system normally shows about 13.5–14.5 V. If the reading stays close to resting battery voltage (around 12 V or lower), the alternator is no longer charging and replacement is the correct fix.
