Cost depends on the location of the wiring damage.
If the switch and wiring are perfect, the UCH itself may be faulty. A common issue on Renault Megane II and III is water ingress into the UCH (located behind the glovebox or under the dashboard), which corrodes the internal PCB and disrupts the door switch input circuit.
If you plug an OBD-II scanner into a vehicle and read code , you are dealing with a localized system fault rather than a vehicle manufacturing platform. Under the standardized OBD-II system, "B" stands for Body , meaning the error is registered by an auxiliary module like the Body Control Module (BCM), Airbag/SRS Module, or Instrument Cluster.
