Jaguar XE Active Hood Fault After Safety System Deploy

Just had my latest service at 137940 KM, and similar warnings appeared shortly after. The impact sensor definitely needs checking as part of the diagnosis. My hood latch was physically deployed, and the mechanic confirmed the pedestrian safety system had activated. Getting it properly diagnosed next week, as the car safety system warnings suggest multiple faults. The repair costs seem reasonable based on the quote I received, which was around 290€. Has anyone tried resetting the system without component replacement?

Thanks for the additional details about your Jaguar XF. Based on what you described, I strongly advise against attempting just a system reset. When I faced this issue, my initial thought was also to try resetting, but the crash detection system had legitimate reasons for activation. The fact that your hood latch physically deployed indicates the system fault is beyond a simple software issue. The collision detection module and impact sensors work together as an integrated safety system, just resetting without addressing the underlying trigger could compromise the pedestrian safety features. In my case, even after a reset, the warnings kept returning because the acceleration sensor was genuinely faulty. The 290€ quote you received seems in line with what I paid (315€) for a proper fix including parts and labor. The proximity to your recent service is interesting, this could indicate the safety system picked up an issue during maintenance work. When addressing active hood faults, its crucial to have all system components properly diagnosed and calibrated, not just reset. My recommendation would be to proceed with the full diagnostic and repair as planned. These advanced safety systems are complex and interconnected, partial fixes often lead to recurring issues.

Appreciate the detailed responses and recommendations. After getting more feedback about the system fault, I definitely see why a proper repair is needed rather than just attempting a reset. Since the pedestrian safety system actually deployed and the hood latch was activated, it makes sense that component replacement will likely be necessary. I will proceed with the full diagnostic and repair next week as planned. The 290€ quoted cost seems fair based on others experiences with similar car safety system repairs. Just hoping the impact sensor is the main issue and no additional components need replacement. Will update once I get the final diagnosis and repair completed.

I had a similar issue with my 2019 Jaguar XF, and with some experience working on modern car electronics, I can share what worked for me. The acceleration sensor in my car failed, triggering false pedestrian safety system alerts and activating the hood mechanism. The car safety system kept showing warnings, just like yours. After multiple diagnostic attempts, the workshop found that the sensor was sending incorrect signals to the collision detection module. The repair involved: Complete diagnostic scan, Replacement of the faulty acceleration sensor, Recalibration of the safety system, Reset of the active hood mechanism, System verification tests Total cost was 315€, including parts and labor. The repair took about 4 hours to complete. Before suggesting specific solutions for your case, could you provide: Exact error codes showing on your display, Whether the active hood physically deployed, Any unusual events before the warnings appeared, Mileage of your vehicle This information would help determine if your issue matches what I experienced or if it might be something different in your car safety system. Would also recommend not delaying the repair, as these warnings could indicate compromised safety systems.
