BMW i4 Active Hood System Failure Sparks Safety Alert

I faced something similar with my 2018 BMW iX3 last year. The acceleration sensor triggered a false reading, which activated both the active hood and lit up the airbag warning. The active hood system is a crucial safety feature, so this definitely needs attention. When I took it to the garage, they diagnosed it as a faulty sensor unit. The repair involved replacing the acceleration sensor and resetting the active hood actuators. Not a quick fix, they had my car for two days. It's a serious safety system issue that needs proper attention from certified techs with the right diagnostic tools. One tip, make sure they check the entire sensor network, not just replace the obvious parts. In my case, they found some corrosion in the connecting terminals that needed cleaning too. You'll need a BMW specialist for this one, it's not something for a general mechanic, as they'll need specific programming tools to reset the system properly. Best of luck with the repair.

Thanks for sharing your experience! Really helpful to know about that sensor issue. I've actually got an appointment booked for next week. Just curious, do you remember roughly how much you ended up paying for the whole thing? Also, has everything been working fine since the repair, or have you noticed any other quirks? Cheers! Mark

Good to hear from you again! Just thought I'd follow up, I actually got this sorted last time and it cost me 315 € total for fixing that pesky acceleration sensor. The mechanic confirmed it was definitely faulty, just like I suspected. Since the repair, my active hood system has been working perfectly, no more warning lights or false triggers. They did a thorough job with the diagnostic and repair work, and honestly, it was worth every penny. The whole system's been running smooth as silk for months now. No quirks, no warning lights, nothing to worry about. Sometimes you just need to bite the bullet and get these things fixed properly, you know? Let me know how your appointment goes next week. Always good to compare notes on these things, helps everyone in the community.

Just wanted to update you on my BMW situation. Finally got it checked out and fixed, what a relief! The mechanic I found was actually pretty decent. They spotted the same acceleration sensor issue you mentioned, but also found some damaged wiring that needed sorting. Ended up being a bit pricier than your repair, set me back about 450 € with the extra wiring work. But honestly, after all the stress with those warning lights, it's worth it just to have peace of mind. Car's running perfectly now, and all those annoying warnings have disappeared. Thanks again for your advice earlier, really helped me know what to expect when I went in. Sometimes it's just good to hear from someone who's been through the same thing. Catch you later, Mark
