Product Information

Full details

The Hella Blind Spot Detection Control Unit (6PZ 011 719-261) is an essential electronic component designed for automotive technicians and vehicle owners looking to restore or maintain advanced driver assistance systems (ADAS). Acting as a slave control unit for the vehicle's safety network, it provides reliable data processing for blind spot monitoring at the rear-left position. While this unit is engineered to high OE standards, it requires professional installation and specific diagnostic software activation, meaning it is not a plug-and-play solution for DIY enthusiasts without specialized diagnostic tools.

No, this specific part number is designed exclusively for the left rear position.

What OEM part number does this replace?

It is a direct replacement for OEM reference 5Q0907685B.

Yes, calibration is generally required to ensure the system accurately registers distances and objects relative to your vehicle.

What is the operating voltage of this unit?

What happens if I don't code the module?

The vehicle's gateway will not recognize the new hardware, and the blind spot monitoring system will remain disabled or display a fault light.

Setup, Compatibility & Care

Compatibility Check: Before purchase, verify your vehicle uses the OEM reference `5Q0907685B`. This unit is strictly for the left rear side of the vehicle and is not interchangeable with the right-side unit.

Installation Requirements:

  1. Ensure the vehicle battery is disconnected before accessing the rear bumper or trim area.
  2. Mount the unit securely in the factory-specified location.
  3. Reconnect the electrical harness, ensuring the locking mechanism clicks into place.
  4. Activation: The unit must be coded and calibrated using professional diagnostic software (such as VCDS or factory-level tools) to pair with the vehicle's gateway module.

Care: Avoid high-pressure water contact directly on the module connector. Ensure the area remains free of moisture and debris during installation to prevent corrosion on the harness pins.
