Fiat Mobi ABS Light Lateral Acceleration Sensor Fault

That sounds like a nasty problem. I had a similar issue with my previous 2016 Opel Corsa, although it was related to the yaw rate sensor and vehicle stability control. The symptoms were almost identical. Do you notice any difference in how the car handles, especially during cornering or quick lane changes? Steering angle and electronic control might be affected.

Thanks for the quick reply! You mentioned a yaw rate sensor issue on your Opel. Was that also accompanied by the ABS light and error codes? I have checked steering, it seems fine but I suspect this could get worse, given the error.

Yes, it was also accompanied by the ABS light illuminating. In my case, the root cause ended up being a faulty control unit. If the error codes are pointing directly at the lateral acceleration sensor, it's highly likely you are facing a similar control unit failure. At this point, I'd strongly advise against trying to diagnose it yourself and instead take it to a reputable workshop; diagnosing this is not cheap.

Understood, I appreciate the insights and sharing your experience. I took it to the shop, and they confirmed the control unit is indeed defective. Repair cost is estimated at 1000€. Not cheap, but at least it's getting sorted. Thanks again!
