Mercedes-Benz W212 Trunk Lid Latch Actuator A2047500084 - Used Original Parts

Diagnosis and Common Symptoms

From a workshop perspective, failure of the A2047500084 trunk latch actuator is a common issue on the W212 platform. Diagnosis often begins with the client reporting an inability to open the boot via the key fob, interior switch, or the exterior handle. You may hear a faint click from the Rear SAM (Signal Acquisition Module) attempting to energize the latch, but the mechanical release fails to engage.

Conversely, a critical failure mode is the inability for the trunk lid to securely latch, causing it to pop back open. This triggers a persistent "Trunk Open" warning on the instrument cluster, even when the lid is physically closed, due to a faulty internal microswitch. On a diagnostic tool like XENTRY, you may find fault codes pointing to an open circuit, short circuit, or implausible signal from the trunk central locking motor or its position sensors.
