C3 Electronic Parking Brake Failure

I did preliminary brake diagnostics using an OBDII scanner, which indicated a fault within the electronic parking brake system, but the error code didn't pinpoint the electric motor. What steps did you take to isolate the issue and did your diagnostic process yield a more conclusive result?

My diagnostic pointed towards the electric motor. Considering your symptoms and the error codes you've retrieved, the defective motor is the most likely cause. I would suggest consulting a workshop to confirm before any repair.

I consulted a workshop, and they confirmed the diagnosis of a defective electric motor within the brake caliper. The repair is complete, and the electronic parking brake is functioning again. Your assistance guided me to a prompt and effective resolution. Thank you.

I also own a C3 and experienced a similar electronic parking brake issue recently. Did you perform any brake diagnostics to confirm the electric motor failure? In my case, the symptoms were identical to yours.
