FAQs

Is this a genuine Audi part?

This is a high-quality aftermarket replacement by D2P, designed as a direct replacement for the OEM part number 8K0941309D.

Can I install this myself without tools?

You need basic hand tools to remove the mounting bolts and a diagnostic scanner to perform the necessary software calibration.

Will this fix my 'Headlight Range Control' warning?

Yes, if the warning is caused by a faulty rear left height sensor, this part will resolve the issue once calibrated.

Does it matter if I have an S-Line or base model?

This part is designed for the specified A4 B8 and A5 chassis; however, always cross-reference your specific part number before purchase.

What tools are required for calibration?

You will need an OBD-II diagnostic interface, such as VCDS (VAG-COM), to communicate with the vehicle's leveling module.

Troubleshooting

Headlight error light remains on after installation

The system requires a software recalibration using an OBD-II diagnostic tool to clear old error codes and set the new sensor zero-point.

Unstable sensor readings

Check the 4-pin connector for bent pins, moisture, or corrosion, and ensure the linkage arm is attached correctly to the suspension arm.

  • Essential for fixing self-leveling headlight errors
  • High-quality 4-pin connection ensures stable signal transmission
  • Restores proper suspension height telemetry

  • Sensitive electronic component requires careful handling

Setup, Compatibility & Care

Compatibility: This sensor is compatible with Audi A4 B8 (2007–2017) and Audi A5 models. Always verify the part number 8K0941309D matches your existing unit before purchase.

Installation Steps:

  1. Secure the vehicle on jack stands or a lift.
  2. Locate the suspension arm on the rear left side to identify the old sensor.
  3. Disconnect the 4-pin electrical harness carefully.
  4. Remove the mounting bolts and the linkage arm connected to the suspension.
