Peugeot Boxer / Fiat Ducato / Citroën Relay Airbag ECU Repair | B0100 Internal Error Fix (Mail-In Service)

1) What You’re Buying — Airbag ECU Repair Service (Your Module, Mail-In) ⚠️📦

• Service Only — Not a part: You send us your airbag ECU (SRS module). We diagnose and repair common internal error / grounding / no-comms faults, then return the same unit.
• Common fault we fix: B0100 internal ECU error (often seen as B0100-49). This is frequently linked to low/bad battery voltage or voltage spikes.
• Also supported (message first): B0102-00 ECU grounding / connection to ground fault, and cases where the ECU shows no communication with the vehicle or diagnostic tool.
• Result: Restored communication and correct operation where the issue is within the ECU and repairable. ✅

Important: This listing is for repair of your existing ECU (not a crash data reset). If your vehicle has deployed airbags/pretensioners or wiring faults, those must be repaired first. Flood/water damaged or physically crushed units may be non-repairable — we will advise.

2) How to Order & Send — Message Us First ✉️📦

1. Message us on eBay with your ECU part number and the fault code(s) (e.g. B0100-49, B0102-00, No Communication). A clear label photo helps. We usually reply fast. ✅
2. After we confirm it’s suitable, click Buy It Now on this listing.

Quick FAQ 💬

• Is this a replacement ECU? No — this is a repair service for your own ECU once you send it to us.
• Will it definitely fix my fault? If the fault is caused by a repairable ECU issue (common with B0100/B0102/no-comms), yes in most cases. If the vehicle has wiring/power/ground issues, those must be fixed too.
• What causes B0100-49? Often low battery voltage, weak battery, poor charging, jump-start spikes, or corrosion/poor connections.
• My ECU is totally dead / no comms? We can often help — message first with details, as severity varies.

This listing is for a postal repair service on your own airbag ECU. You are not buying a new, used, exchange or reconditioned unit. If we cannot complete the repair due to non-repairable damage, we’ll return the ECU and advise next steps.
