Amarok Hood Fault Triggers Safety System Malfunction

Just had my 24931km service done last month. The crash detection system started acting up shortly after. The diagnostic scan showed error code P1A23, exactly what you described with the hood latch and airbag warnings. My mechanic found that water had gotten into one of the front impact sensors, causing the system fault and false triggers in the hood safety system. The car electronics were getting confused signals, similar to what happened with your Atlas. The fix was less expensive in my case, just needed to replace the corroded sensor wiring and seal the connection properly. Total repair cost was 180€. No issues since then and all safety systems are working normally now. Worth checking the wiring near your front sensors for any signs of moisture damage or corrosion. This seems to be a known weak point in the system.

Thanks for sharing your repair experience. The water damage causing system faults is actually quite common in these models. After my sensor replacement, I had the workshop add extra waterproofing around all collision detection components to prevent future issues. The price difference between our repairs makes sense, you caught the corrosion early before it damaged the sensor itself. The car electronics in these models are pretty sensitive to moisture, especially around the hood latch and impact detection areas. Since your fix worked, I might have my workshop check the waterproofing on my replacement sensor during the next service. Car safety systems are interconnected, so preventing moisture issues is crucial for reliable operation. One tip from my experience: regularly inspect the drainage channels near the hood sensors, especially during wet seasons. Blocked drainage can lead to water accumulation and trigger these system faults again. Would you mind sharing if your mechanic applied any specific sealant type? Mine used standard protection but I am looking for more durable options.

Good to know about the waterproofing improvement suggestion. My mechanic used a special marine-grade silicone sealant rated for automotive use. Its a bit more expensive but should last longer than standard protection. Looking back, glad I caught the corrosion early. The collision detection system is too important to risk compromising. After researching similar cases online, seems the front impact sensor wiring is a common failure point that can trigger various safety system faults. Will definitely keep an eye on those drainage channels you mentioned. Already added it to my monthly maintenance checklist. Makes sense that blocked drainage could cause these problems, especially with how sensitive the car electronics are in these newer models. For anyone else reading this, dont ignore warning lights related to car safety systems. Getting it checked early saved me from a more expensive sensor replacement and prevented potential issues with other connected safety features.

Had a similar issue with my 2021 VW Atlas, also diesel. The pedestrian safety system was giving false readings, triggering the active hood and lighting up the airbag warning. After some digging, the workshop found a faulty acceleration impact sensor that was sending incorrect signals to the safety system control unit. The repair involved replacing the defective sensor and recalibrating the entire pedestrian protection system. Total cost was 315€ including diagnostic time. Since the fix, no more unusual activations or warning lights. Before jumping to conclusions though, could you share: Exact error codes from the diagnostic scan, Whether this happened suddenly or developed over time, If you notice any damage or corrosion around the hood sensors, If there were any recent repairs or maintenance done These details would help determine if your issue matches what I experienced. System faults in car electronics can be tricky to diagnose without complete information. Also worth noting, driving with active safety system faults isnt recommended as it could affect other connected safety features.
