You mention wheel alignment impacting the stability system. Could you elaborate on the connection between wheel alignment and the lateral acceleration sensor's function? I want to be sure before I pay a mechanic.

Well, with my Volvo, the thinking was that if the wheels weren't aligned correctly, the car's computer thought it was constantly in a skid. The error was similar to yours. To be honest I am not technically savvy but I would recommend going to a workshop.

After consulting with a trusted technician, it seems the control unit is indeed defective, as suspected. The repair, including a new unit and recalibration, is projected at 1000€. A hefty sum, but the safety implications necessitate immediate attention. Your input was valuable.

I had something similar happen with my old Volvo. The stability control would just go nuts sometimes, especially on the highway. Did you check your wheel alignment recently? A bad alignment can mess with the stability system.
