Peugeot 308 ABS Fault

Has anyone experienced a speed signal fault with ABS, traction, or odometer issues on their 2023 Peugeot 308 electric? I'm seeing the ABS lamp, traction problems, and potential ABS failure at 176709 km. Diagnostics point to a defective control unit. Any advice on scope, transmission ramifications, or safety?

I have a Peugeot 308 and had similar issues. The ABS light would come on intermittently, and I could feel the traction control cutting in at strange times. It felt like the car didn't know how fast it was going. Have you checked the wheel speed sensors? That's where I would start.

Thanks for the quick reply. Could you share more about the symptoms you saw and whether the diagnostic pointed directly to a sensor issue, or also the ABS control unit? Were there any error codes with the odometer?

My local mechanic connected the diagnostic tool and confirmed that the ABS control unit was faulty. He also mentioned that a defective control unit can cause communication problems with the wheel speed sensors. I think it is best if you let a workshop check your car to be sure.

Thanks for the helpful advice and for sharing your experience. A workshop confirmed a defective ABS control unit, needing replacement. The estimated repair cost is about 1000€. I will proceed with the repairs.
