Mercedes-Benz W221 Exterior Door Handle Keyless Go A2217600334 - Used Original Parts

Diagnosis and Common Symptoms

From a workshop perspective, failure of the W221 Keyless Go door handle is a common issue, typically isolated to a single door. The primary symptom is a complete or intermittent loss of the touch-to-lock or pull-to-unlock function on the affected handle, while the other doors operate correctly. The internal capacitive sensors and microswitch are susceptible to water ingress and electronic fatigue over time.

On a diagnostic tool like XENTRY, you will often find stored fault codes pointing to a signal implausibility or malfunction in the specific handle's sensor (e.g., S62/1 for the front left door). While the central locking will still function via the key fob, the seamless convenience of Keyless Go is lost for that door, which is the core indicator for replacement.
