While primarily a diagnostic code, the "098" prefix appears in other Peugeot-related technical areas:

: The code 098A is often associated with the Adaptive Cruise Control (ACC) radar module (OEM part number 9820282980), which is a critical safety component in newer models like the 3008 and 5008.

: The front right dipped beam fails to illuminate, even after the bulb is replaced.

: The "098C" designation has also been linked to compressor control valves for Sanden units used in Peugeot models from 2005–2015.

: A "Service" light or a "Bulb Fault" message may appear on the instrument cluster.

Fixing a 098C error usually requires a systematic approach to the vehicle's electrical system:

: Since the code refers to the engine fuse box, check for blown fuses or signs of water ingress, which is a common issue in Peugeot models like the 308 or 3008.

If you are seeing this code on a diagnostic tool like Diagbox or Lexia, it is highly recommended to test the at the engine fuse box to determine if the module itself needs replacement or if the issue is purely in the external wiring.

: Sometimes the BSI "locks" a circuit after detecting a short. A BSI reset procedure (a specific battery disconnection sequence) can sometimes clear "phantom" faults.
