2018-2021 Audi SQ5 ADAS Camera: Decoding 'Pre Sense Limited' Faults and Calibration
This guide covers the common failure symptoms, mandatory calibration requirements, and how to choose a reliable used ADAS camera for your 2018-2021 Audi SQ5.
- Professional calibration is mandatory after replacing the camera, replacing the windshield, or performing a wheel alignment; this is not a DIY job and is a significant part of the total cost.
- The most common failure symptom is the "Audi pre sense: currently limited" warning on the dashboard, which disables key safety features.
- Used OEM cameras are a viable, cost-effective option, but you must match the part number (e.g., 80A907217A or 80A907217B) and inspect the part for damage.
- New aftermarket replacements are not readily available, making new OEM or used OEM the primary choices.
Symptoms of a Failing ADAS Camera
When the ADAS camera in a 2018-2021 Audi SQ5 begins to fail, you will typically see specific warnings on the instrument cluster or virtual cockpit. These messages indicate that one or more driver assistance features are disabled.
- "Audi pre sense: currently limited. See owner's manual": This is the most common message. It means that the vehicle's automatic emergency braking and collision warning systems are not fully functional. This can be caused by a dirty windshield, heavy rain, or a genuine fault with the camera or related sensors.
- "Active lane assist: currently unavailable. No camera view": This message specifically points to a problem with the forward-facing camera, disabling the lane-keeping function.
- Adaptive Cruise Control (ACC) is unavailable: If the camera data is compromised, the ACC system may not engage or will shut off unexpectedly.
- Diagnostic Trouble Code (DTC) C110702: When scanned with a diagnostic tool, a fault code of C110702, described as "Video line for image processing Signal error," often indicates 🎬 Watch this guide on fixing and installing an Audi camera with code C110702 an internal hardware failure within the camera module.
Pro Tip: Before assuming the camera has failed, thoroughly clean the windshield area in front of the camera. Also, be aware of Audi's Technical Service Bulletin (TSB) 2059891/7, which states it is normal for a "pre sense not available" message to appear for up to 20 seconds after starting the vehicle while the system initializes.
Known Issues, TSBs, and Recalls
While there are no major recalls specifically for the forward-facing ADAS camera on the 2018-2021 SQ5, the broader Audi lineup has experienced several software-related camera issues. This highlights the sensitivity of these systems to software glitches.
- TSB 2059891/7: Informs owners that a temporary "pre sense not available" message on startup is normal system behavior and not a fault.
- Recall 90S9 / NHTSA 21V-947: This recall affects 2018-2022 SQ5 models but pertains to the gateway control module under the rear seat. Spilled liquid can damage this module, leading to widespread electronic issues, including ADAS warnings. The fix involves installing a protective cover.
- Numerous Rearview Camera Recalls (90TV, 91DZ): Multiple recalls were issued for other Audi models, including the 2021 SQ5, for software errors that caused the *rearview* camera to display a black screen. 🎬 See how technicians perform VW and Audi surround view camera calibrations While not the same part, this pattern shows that software updates are a common fix for camera-related problems on this platform.
Replacement and Mandatory Calibration
Physically replacing the ADAS camera is relatively simple; it typically unclips from a bracket on the windshield. However, the critical and non-negotiable step is the ADAS calibration that must be performed after installation.
Calibration is a process that precisely aligns the new camera with the vehicle's centerline to ensure it accurately interprets the road. This procedure is not optional and cannot be done at home. It requires a controlled workshop environment with specific targets placed at precise distances from the vehicle, along with Audi's proprietary diagnostic software (ODIS) 🎬 Watch a complete tutorial on front camera ADAS calibration for modern Audis to complete the alignment.
Warning: Skipping calibration after a camera replacement, windshield replacement, or even a wheel alignment can cause safety systems to fail. The vehicle may not brake in time, or it could steer incorrectly, creating a significant safety risk.
Buying a Used Advance Driver Assistance System (ADAS) Camera
Purchasing a used OEM ADAS camera is a cost-effective alternative to a new dealer part, especially since new aftermarket versions are generally not available for this component. However, there are important factors to consider.
- Verify the Part Number: The most common part numbers for the 2018-2021 SQ5 are 80A907217A and the superseding part 80A907217B. Always match the part number from your original camera or confirm compatibility with the seller using your vehicle's VIN.
- Physical Inspection: Before purchasing, carefully inspect photos of the used unit. Look for any scratches, chips, or haziness on the camera lens. Check the plastic housing for cracks and ensure the electrical connector pins are straight and free of corrosion.
- Source Matters: Buy from reputable auto recyclers that offer a warranty and clear photos of the actual part you will receive.
- Budget for Calibration: Remember that even a perfectly functional used camera will require professional calibration after installation. Factor this significant cost into your total repair budget.
Cost Comparison for ADAS Camera Replacement
The total cost can vary significantly based on the source of the part and the labor rates for installation and calibration.
| Part/Service | Estimated Cost | Notes |
|---|---|---|
| New OEM Part | $560 - $840 | Price from online Audi parts dealers or as estimated by repair services. Dealer direct quotes can be higher. |
| New Aftermarket Part | Not Available | Complex electronics and software mean aftermarket options are not common for this part. |
| Used OEM Part | $80 - $200 | Commonly found on eBay and from specialized auto recyclers. |
| Remanufactured (Repair Service) | ~$850 | Specialized services can repair the electronics of your original module. |
| Shop Labor (Installation) | $85 - $125 | Reflects ~1.0-1.5 hours for the physical swap. |
| Shop Labor (Calibration) | $250 - $800+ | Independent shops are typically $250-$500, while dealer calibration can be $800 or more. |
Frequently Asked Questions (FAQ)
Can I replace the ADAS camera myself to save money?
While you can physically swap the camera module yourself, you cannot complete the job. The mandatory calibration requires specialized tools and software that only professional repair shops or dealerships possess. Failure to calibrate will leave the system inoperative and unsafe.
Why is ADAS calibration so expensive and necessary?
Calibration is expensive because it requires a significant investment in specialized targets and official diagnostic software, plus the technician training to use it correctly. It is necessary because even a one-degree misalignment of the camera can translate to several feet of error at highway speeds, potentially causing the automatic braking or lane-keeping systems to react incorrectly or not at all.
Will a used camera from another SQ5 work in my car?
Yes, a used camera with a matching part number (e.g., 80A907217A or 80A907217B) should be compatible. However, it will still need to be professionally calibrated to your specific vehicle after installation.
My windshield was just replaced and now I have ADAS errors. Is the camera broken?
The camera is likely not broken. Audi requires ADAS calibration any time the windshield is replaced. The glass shop should have performed or arranged for this service. If they did not, the system is now misaligned and throwing errors. You will need to take it to a qualified shop for calibration.
