Technical Information
- Manufacturer: Stellantis / Citroën Peugeot
- Model: Peugeot 406 2.0 HDi
- Product Codes: 9642946280, 6104W7
- Additional Numbers: NFP (as indicated)
Fitment / Compatible Vehicles
Compatible with Peugeot 406 models equipped with the 2.0 HDi engine. Typically fitted in passenger car variants of the 406 range; verify product codes against workshop documentation or parts catalogue when in doubt.
Function
The cluster provides continuous readout of vehicle speed and displays the total mileage (odometer). It also contains the tachometer, fuel and temperature indicators (depending on variant), and a set of warning and status LEDs for engine, ABS, airbag and other vehicle systems. Proper operation of the cluster is essential for safe driving and diagnostics.
Installation Recommendations
- Always disconnect the negative battery terminal before starting removal to avoid short circuits and potential damage to the electronics.
- Remove trim panels and lower steering column cover to access the cluster; retain all screws and fasteners in order.
- Unscrew the cluster mounting screws (typically Torx) and carefully pull the unit forward to access electrical connectors.
- Release connectors by the locking tabs—do not pull on wiring. Inspect connector pins for corrosion or damage and clean if necessary.
- After installation, reconnect the battery and verify all indicators, backlighting and gauges operate correctly. Perform any necessary instrument self-tests as described in the vehicle service manual.
- If transferring data between clusters (odometer, configuration), follow local legal requirements and workshop procedures.
Why This Part Most Commonly Fails
Instrument clusters can fail for several reasons: stepper motor wear (affecting gauge movement), failing solder joints or electronic components on the circuit board, backlight or display degradation, and moisture ingress leading to corrosion. Vibration and thermal cycling over years of service accelerate wear on connectors and moving elements. Regular checks of connector condition and keeping the cabin dry help extend service life.
