Q2: How do I confirm that 9807028780 is the correct fuse box for my car?

A2: To verify fitment:

  1. Inspect the existing fuse box in your engine bay for part numbers look for “9807028780” or equivalent references.
  2. Check cross‑reference numbers listed in the product listing (e.g. 9807028880, 9807028680, 9675878280 etc.)
  3. Use your VIN or vehicle registration in parts databases, or ask us to confirm compatibility.

  • Multiple electrical failures (e.g. lights, alternator, fan, sensors)
  • Vehicle does not start or stalls unexpectedly
  • “Battery not charging” or “Fuse fault” warnings on the dashboard (some Citroën / Peugeot owners report this)
  • Clicking or buzzing noises from the fuse box area under ignition
  • Erratic or intermittent functioning of relays housed in the BSM (e.g. wipers, washer pump)
  • After battery change, the car fails to reinitialize or shows fault codes

Q4: Is replacing the BSM fuse box 9807028780 a do‑it‑yourself job?

A4: It depends on your experience with automotive electrical systems:

  • Removing the battery or disconnecting power is essential before handling the fuse box.
  • Carefully detach all electrical connectors, relays, and fuses (note their originaI position).
  • Transfer components (fuses, relays) and mount the new unit securely.
  • After installation, test all electrical functions and check for error codes.
  • In many cases, the replacement is plug‑and‑play if you use the correct variant; no programming is required.
  • But if you’re unsure or find wiring complex, it’s safer to engage a qualified technician.

Q5: Does the BSM 9807028780 require coding or initialization? 

A5: In most documented cases, this fuse box is a direct replacement (plug‑and‑play) and does not require coding, as long as the correct variant is used. However, after installation you should:

  • Clear any fault codes with a diagnostic tool
  • Check that all systems (lights, sensors, starting, alternator) are functioning normally
  • If issues persist, some special cases may require software initialization.
