Intended Use and BMW Compatibility

The set is dedicated to BMW E81, E82, E87, E90, and E91 vehicles equipped with the front PDC system. The placement on the vehicle is the front, meaning the sensors operate in a critical maneuvering zone – when parking forward, approaching obstacles, or maneuvering in tight spaces. The use of original BMW solutions ensures correct cooperation with the factory control unit, electrical system, and acoustic and visual signaling in the vehicle.

Quarzblau Metallic - A18 Color and Visual Aspect

The factory finish in Quarzblau Metallic - A18 allows for installation without the need for additional painting, provided the bumper is in the same shade. This is particularly important for vehicles where maintaining a uniform paint coating and visual consistency of body elements is crucial. Sensors in this color integrate well with the bumper line, not visually detaching from the rest of the car body, which is important for both restoration and post-accident repairs.

PDC Set Functionality and Performance Parameters

The set includes four parking sensors, which corresponds to the typical configuration of the front PDC system in many BMW models. Such a set allows for:

• restoring full parking system functionality after damage to multiple elements simultaneously,
• consistent replacement of sensors in one vehicle zone,
• maintaining uniform operating characteristics of all sensors on the front bumper.

Using a set from the same series facilitates diagnostics and minimizes the risk of sensitivity differences between individual sensors. This is especially important in vehicles where the PDC system is heavily used in daily urban operation.

Condition, Installation, and Service Application

The components come from the Other category, meaning they are specialized components primarily used for repairs of parking assistance systems and bodywork/painting tasks. As a used part, the set is intended for users and workshops looking for technically proven solutions while maintaining reasonable repair costs. Installation should be carried out by someone experienced with PDC installations in BMW, ensuring correct seating in the bumper sockets and proper connection to the wiring harness.

System Expansion and Selection of Other Components

If you are planning a comprehensive repair or upgrade of the front bumper area on your BMW and need other parts from the same group, such as additional sensors, wiring harnesses, or mounting brackets, check the available parts in the Other BMW category.
