Description
OEM part number A2035454932. This is a genuine used Mercedes-Benz PDC control module (parking sensor ECU) for the W203 C-Class. Units are tested and confirmed functional before listing.
This Park Assist (PDC) control module governs the full operation of the parking distance warning system. It activates the ultrasonic sensors in the front and rear bumpers, evaluates the round-trip echo times to determine obstacle proximity and translates those measurements into stepped audible alerts that grow more frequent as clearance reduces. Where a visual aid is fitted, the module also supplies distance data to the instrument cluster or COMAND display. All system communications pass over the vehicle CAN bus.
Typical signs of module failure are the parking sensor system remaining completely silent when reverse is selected, missing warning tones during close-proximity parking, an incessant beeping when no object is detected, a PDC fault lamp or warning message displayed in the cluster or on the COMAND screen, or individual sensors ceasing to respond while adjacent positions remain functional.
The module is in good used condition. Always cross-reference the OEM number with your specific vehicle, model year and option codes before ordering — the Mercedes-Benz range includes numerous PDC module variants and choosing the wrong number will result in a non-functional system. Professional fitting is advised. Following installation, SCN online coding via the Mercedes-Benz Star Diagnosis system is usually necessary; the module will not operate correctly if this step is skipped. 14-day returns apply to unmodified, as-received parts.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
