Seat Alhambra Electronic Parking Brake Issue
Summary of the thread
The electronic parking brake on a 2004 Seat Alhambra was non-functional, with an error stored in the memory and a warning light illuminated. The suspected cause was a defective electric motor in the brake caliper. After confirming the issue with a workshop, the faulty motor was identified as the problem, and the repair resolved the issue.

Wiring harness looks fine at a glance. When yours failed, did it also store an error in the error memory, and show a warning light? Was it a complete brake failure?

Yes, exactly the same symptoms. Error code and the light. It wasn't a complete brake failure in the sense that the regular brakes still worked, but the parking brake was useless. If the wiring is okay, it's almost certainly the motor. Get it to a workshop; messing with the brake system isn't worth the risk.

Thanks for the input. The workshop confirmed the electric motor in the brake caliper was defective. Repair cost was around 505€. Problem solved.

Sounds like a faulty EPB actuator motor. I had the same issue with my Alhambra, electronic brake went haywire. The brake control module probably threw a fit. Did you check the wiring harness for any damage? Sometimes a loose connection can cause a system glitch.
