New original BMW ACC radar / distance sensor – 5A9BE28 / 66315A9BE28

Ensure the highest level of safety, comfort, and reliability of active driver assistance systems in your BMW. We offer a brand new, original ACC radar (distance sensor / active cruise control) with catalog number 5A9BE28 (66315A9BE28), dedicated to a wide range of modern BMW models. Choosing the original OEM part guarantees full compatibility with onboard electronics, hassle-free calibration, and precise operation of advanced safety systems.

Why is the original BMW ACC radar the best choice?

The Active Cruise Control (ACC) system and Driving Assistant packages rely on extremely precise measurements of distance and speed of preceding vehicles. Cheap replacements or used sensors of unknown origin often cause communication errors with the main controller, prevent proper calibration, cause false braking, or completely block the active cruise control operation. The original OEM radar ensures factory precision, weather resistance, and reliability in all driving conditions.

Key Product Advantages:

• OEM Quality: 100% original BMW product, identical to the factory-installed component.
• Precise Detection: Advanced radar system ensuring smooth operation of active cruise control, distance control, and emergency braking systems.
• Perfect Integration: Full compatibility with vehicle electronics, DSC/DME controllers, and Driving Assistant systems.
• Durability: Construction resistant to stone impacts, changing weather conditions, moisture, and extreme temperatures.
