Cost of B173D Peugeot Work (Parts & Labor)
Understanding the financial aspect helps you decide between DIY and a professional garage.
| Repair Type | Parts Cost | Labor (Shop) | Total Estimate (USD/EUR) | | :--- | :--- | :--- | :--- | | Replace pre-heat relay only | $25–$50 | $60–$100 | $85–$150 | | Replace BPGA unit | $250–$400 | $100–$150 | $350–$500 | | Replace battery + BMS coding | $180–$250 | $50 | $230–$300 | | Full diagnosis + BPGA replacement | N/A | $150–$200 | $400–$600 |
Pro Tip: Avoid aftermarket BPGA units. PSA proprietary parts are required for CAN bus communication. A cheap clone may work for a week, then fail with the same B173D code.
Quick cost/effort guide (typical)
- DIY minor wiring repair: low cost, 0.5–2 hours.
- Latch actuator replacement (parts + labor): moderate cost, 1–2 hours.
- BCM diagnosis/software update at dealer: diagnostic fee + possible reprogramming cost.

What is Fault Code B173D on a Peugeot?
In the context of Peugeot’s (PSA Group) diagnostic architecture, B173D is a manufacturer-specific body control code. Unlike generic OBD2 codes (P0300 for misfire, for example), B-codes relate to internal body electronics, lighting, and power management.
Technical Definition:
B173D typically translates to: “Battery Management System: Relay for Pre-Heating or Auxiliary Power Supply – Functional Failure.”
In simpler terms: The vehicle’s Battery Management System (BMS) has detected an inconsistency in the pre-heating circuit (for diesel models) or the auxiliary power relay that manages power distribution to critical modules like the Electronic Control Unit (ECU), fuel pump, or glow plug system.
Common Peugeot Models Affected:
- Peugeot 208 (1.6 BlueHDi)
- Peugeot 2008 (1.5 BlueHDi)
- Peugeot 308 (Diesel variants)
- Peugeot 3008 (Phase 1 & 2)
