Mercedes-Benz W205 Parking Sensor A0009055504 - Used Original Parts

Diagnosis and Common Symptoms

As a technician, when a W205 C-Class comes in with a parking assist issue, the first suspect is often one of these sensors. The primary indicator is the "Parktronic Inoperative" message appearing on the instrument cluster, usually accompanied by the system deactivating completely. You may also experience intermittent false alarms where the system beeps erratically even with no obstacles nearby, a common sign of internal sensor failure or water ingress. A diagnostic scan with a capable tool will typically reveal fault codes pointing to a specific sensor location (e.g., "Front Inner Left Sensor Signal Implausible"). A dead sensor will show no signal, while a failing one might give erratic distance readings before giving out entirely.
