VW Up Hood Latch Fault Triggers Safety Alerts

Recently dealt with a similar hood latch sensor issue on my 2015 VW Polo TSI. The active hood system, which is part of the pedestrian safety features, started showing identical warning messages. The fault turned out to be serious since it affects both crash detection and airbag systems. When the acceleration sensor becomes defective, it compromises the entire safety system network. The car electronics need a complete diagnostic scan to identify if its just the sensor or wider system damage. In my case, the hood latch sensor connector had corroded, affecting signal transmission to the main safety module. The repair involved replacing the front impact sensors and recalibrating the car electronics. This wasnt a quick fix, the system needed specialized diagnostic equipment to properly reset all safety parameters. Given that these systems are interconnected, driving with active fault warnings means collision detection and airbag systems might not function correctly. Would strongly recommend getting this checked soon by a certified workshop that has experience with VW safety systems. The repair requires specific diagnostic tools and expertise in calibrating multiple sensor systems. While its not a breakdown risk, its definitely a safety concern that shouldnt be postponed.

Thanks for sharing your experience with the VW Polo sensor issue. Mine turned out to be quite similar with the corroded hood latch triggering multiple car safety warnings. The impact sensor replacement and recalibration fixed everything. Can you remind me what the total repair cost was for your case? Also curious if youve had any recurring issues with the crash detection system since the fix? My car safety module seems fine now but always good to know what to watch for.

Glad to hear you got it sorted. After taking my Polo to the mechanic, the active hood fault warning completely disappeared. The final bill came to 315€ for replacing the faulty acceleration sensor and performing the necessary system recalibration. Since the repair, all car electronics and collision detection systems have worked flawlessly. No recurring issues with any safety warnings or car sensor malfunctions over the past 8 months. The impact sensor replacement seems to have fully resolved the problem with the hood latch system. A properly functioning crash detection setup is crucial for safety, so its reassuring to have everything back to normal. Keep an eye on your warning lights, but with a fresh sensor installed, you shouldnt see any further problems with the active hood system.

After getting your feedback about similar issues, I took my VW to the dealership mechanic last week. The diagnosis confirmed exactly what you mentioned, a corroded hood latch sensor causing multiple safety system alerts. The repair took about 4 hours total, including full diagnostics and recalibration of the car electronics. The final cost was 290€, slightly less than yours, and included a new crash detection sensor plus complete safety system reset. The mechanic explained that these active hood faults are somewhat common in VWs of our age range. Since the fix, all warning lights have cleared and the car sensor network is functioning perfectly. Really appreciate your detailed response, it helped me understand the issue and gave me confidence to get it properly repaired rather than trying cheaper alternatives. The safety system is working as intended now, and I feel much better knowing all crash detection features are fully operational.
