Metzger 901057 Sensor Parking Aid

The Metzger 901057 is a high‑performance parking sensor designed specifically for BMW models such as the 5 Series, X3, and X5. It offers precise distance detection, reliable alerts, and seamless integration with the vehicle’s existing electronic systems.

Key Features

• Accurate Distance Measurement: Utilizes advanced ultrasonic technology to detect obstacles from 0.2 m up to 4 m, providing real‑time feedback for both front and rear parking scenarios.
• Dual‑Mode Operation: Works in parking mode (low‑frequency alerts) and driving mode (high‑frequency warnings), automatically adjusting to the vehicle’s speed.
• Seamless Integration: Compatible with BMW’s PDC (Parking Distance Control) system, allowing the sensor to communicate directly with the car’s central computer without additional wiring.
• Compact Design: Small footprint and low profile make it ideal for installation in tight rear‑view mirrors or front bumper areas.
• Durable Construction: Built from high‑quality materials that resist vibration, temperature extremes, and moisture, ensuring long‑term reliability.

Installation Overview

The Metzger 901057 is engineered for straightforward installation. It typically replaces the factory sensor or can be added as an auxiliary unit. The process involves:

1. Removing the existing mirror or bumper cover.
2. Connecting the sensor’s wiring harness to the vehicle’s diagnostic port (usually a 4‑pin connector).
3. Securing the sensor with the provided mounting bracket and ensuring proper alignment for optimal detection range.
4. Testing the system through the car’s infotainment interface or dedicated PDC display.
