Recalibrating the Audi Q3 After Headlight Repair? Don’t Skip It!
So 2020 Audi Q3 dynamic ADAS calibration is complete, but you had to remove the bumper to fix a headlight. Another dynamic recalibration is in your future.
7 Step ADAS; The importance of being aware of all elements of the repair.
Introduction
When a headlight repair requires removing the front bumper, you’re not just fixing lights—you’re throwing off your ADAS. That’s exactly what happened here with this 2020 Audi Q3. After replacing the headlight and removing the bumper, we had to recalibrate the vehicle’s radar system using Otis and the 7 Step ADAS workflow. In this post, we’ll walk through the entire dynamic recalibration process—from setup to green screen confirmation—so you can see exactly what it takes to return this Audi to safe, calibrated condition.
Setting Up for Calibration
Before recalibration begins, follow these prep steps to ensure clean data and a smooth session:
- Preparation:
- Ensure a stable internet connection (critical for Otis scan tool function).
- Launch Otis and select the correct calibration path (guided functions).
- Clear any existing DTCs or tire pressure alerts that could interfere.
- Starting the Calibration:
- Begin by selecting the “Adjustment” option in Otis.
- Otis will provide an estimated completion time and guide you through the dynamic calibration procedure.
- Dynamic Drive Calibration: With everything prepped, we hit the road—literally—for a dynamic drive session.
- Drive at a steady speed on a clean stretch of highway (we chose the Garden State Parkway).
- Otis tracks sensor alignment while you maintain speed and lane discipline.
- The scan tool will indicate when calibration is successfully completed with a green confirmation screen.
Finalizing the Calibration
Once the calibration is complete, Otis will display a green screen indicating success. Follow these steps to finalize the process:
- Post-Calibration Instructions:
- Pull over safely once the green confirmation appears.
- Turn off the engine, then turn ignition on (as prompted).
- Confirm success via Otis—screen will show completion.
- Verification:
- Resume driving briefly at highway speeds (~65 MPH).
- Test adaptive cruise: confirm following distance responds to bar changes.
- Optionally verify blind spot or lane assist accuracy (if applicable).
- Confirm sensor response is smooth and confidence-inspiring.

Why It Matters
This calibration ensures that the Audi Q3’s radar is accurately realigned after a common repair. Many shops forget this step, putting the customer at risk. But with a proper dynamic recalibration, the vehicle is returned to OEM-safe spec, keeping driver assistance systems reliable and precise.
