Mercedes-Benz W176 W246 A/C Compressor A0038304360 - Used Original Parts

Quick Answer

When the A/C in a W176 A-Class or W246 B-Class no longer cools and the compressor has been confirmed as the cause, replacing the compressor is the lasting fix. A tested Genuine used compressor suits Malaysian owners who want an original Mercedes-Benz part at a lower price, with the warranty stated in the quote. It keeps the factory fit and the factory specification, which matters in a system that runs hard in Malaysian heat and humidity.

Diagnosis and Common Symptoms

The A/C compressor on the W176 and W246 (M270 engine, as listed for the W176) is belt-driven and switched by an electromagnetic clutch. Failures usually appear in one of these ways:

• Cabin air is warm or only slightly cool, even though the A/C is on and the blower works.
• The compressor clutch does not engage, or engages briefly and drops out, so the system cycles repeatedly.
• Grinding, rattling or a rough whirring from the belt area when the A/C is switched on, which can point to a worn compressor bearing or internal wear.
• A squeal or belt noise that appears only when the A/C is on, because a stiff or seizing compressor loads the belt.
• Cooling that fades gradually and then stops, sometimes with the A/C button lit but no cold air.
• Stored A/C or refrigerant pressure faults in the climate control, sometimes with a message or warning in the cluster.

Several faults can look like a bad compressor, so rule these out first: low refrigerant from a leak, a faulty pressure sensor, a blown fuse or relay, and a damaged compressor wiring connector. If the clutch engages, the refrigerant pressure is correct and there is still no cooling, or the compressor makes internal noise, the compressor itself is the likely cause. In Malaysia the A/C runs almost every day, so wear and refrigerant leaks show up often.
