Mercedes-Benz W222 Rear Sunshade Motor A2228100220 - Used Original Parts

Diagnosis and Common Symptoms

As a senior technician diagnosing premium German platforms, I frequently encounter rear sunshade failures on the W222 S-Class chassis. The A2228100220 sunshade motor typically fails due to excessive mechanical resistance in the tracks, which leads to internal gear degradation or burned-out motor windings. Common driver symptoms include a grinding or heavy clicking noise originating from the rear parcel shelf, a shade that binds midway, or a sunshade that remains entirely stuck in the deployed or retracted position. When running a diagnostic scan through XENTRY, you will often find fault codes stored in the Rear SAM (Signal Acquisition and Actuation Module) relating to motor activation timeouts, hall sensor signal implausibility, or high-current draw limit switch faults.
