Mercedes-Benz W205 Rear PDC Parking Sensor | C-Class Bumper Radar Spares

Description

Restore flawless low-speed parking protection and maintain your vehicle’s active safety network with this premium Mercedes-Benz W205 Rear PDC Sensor (Park Distance Control / Ultrasonic Bumper Radar). Specifically sourced and verified for the W205 C-Class platform (produced from 2014 to 2021), this genuine ultrasonic sensor is the definitive replacement for vehicles experiencing a disabled Parktronic system, constant flat-tone warning beeps upon selecting Reverse ($R$), or red warning bars illuminating on the rear cabin roof display.

The Rear PDC Sensor works by emitting high-frequency ultrasonic sound waves that bounce off obstacles behind the vehicle, allowing the central parking aid module to calculate exact distance parameters. Because these sensors are mounted flush along the outermost face of the rear bumper skin, they are highly exposed to the elements and everyday driving hazards. The most common cause of failure is a minor low-speed parking bumper tap, which can crack the delicate internal piezoelectric crystal. Additionally, high-pressure car wash blasters can dislodge the internal rubber sealing rings, allowing rainwater to seep into the sensor housing and short-circuit the electronic pins. When a single rear sensor fails, the entire Parktronic network shuts down as a safety measure, leaving your executive sedan vulnerable to blind-spot collisions. Replacing the faulty sensor instantly restores your visual and audible parking assist guides.

Manufactured with premium solid-state internal electronics and a durable composite outer shell, this sensor features a factory-standard diameter profile to pop perfectly into your original rear bumper retention clips. It features the factory-correct multi-pin electrical socket that clips directly onto the rear bumper wiring loom without requiring splicing or modification. Trust TP German Auto Spares for fully verified, workshop-tested Mercedes-Benz parking sensors, electronic modules, and bumper spares that preserve your C-Class’s premium driving conveniences.
