What does 'Audi pre sense warning - contact workshop' mean in the UK?

The 'Audi pre sense warning - contact workshop' message indicates a fault in the car’s pre sense safety system, which includes features like automatic emergency braking and collision detection. This warning means the system is not functioning correctly and requires professional diagnosis.

Audi pre sense is designed to monitor the road and intervene if a potential collision is detected. When the warning appears, it could be due to sensor malfunctions, software glitches, or wiring issues. Common causes include blocked radar sensors (often by dirt or snow), low battery voltage, or a fault in the control module.

If this warning appears, follow these steps:

1. Check for visible obstructions on the front grille or windscreen where sensors are located. Clean them if necessary.
2. Restart the car to see if the warning resets.
3. If the message persists, avoid relying on pre sense features and drive cautiously.
4. Book a diagnostic check at an Audi workshop. Ignoring the issue could compromise safety systems.

Models like the Audi A3, Q5, or e-tron may display this warning differently, but the underlying issue remains similar. Early diagnosis prevents further complications.

The 'Audi pre sense warning - contact workshop' message indicates a fault in your Audi's collision prevention system that requires professional diagnosis at an authorised service centre. This advanced safety system, found in models like the Audi A3, Q5 and e-tron, uses radar sensors and cameras to detect potential collisions and automatically prepares protective measures. The warning typically appears when there's an issue with components like the front radar sensor (located behind the grille), camera system (behind the windscreen), or the system's control unit. In the UK, you should book a diagnostic check at your nearest Audi dealership or VAT-registered independent specialist. While the car remains drivable, safety features like automatic emergency braking or seatbelt pre-tensioning may be disabled until repaired. For accurate diagnosis, technicians will need to read the fault codes using Audi-specific diagnostic equipment like VAS 6154. Common causes include sensor misalignment (especially after windscreen replacement), electrical faults, or software requiring updates. Under UK consumer law, repairs may be covered if your Audi is still under the original 3-year warranty or an approved extended warranty.
