Technical Information

• Manufacturer: Bosch
• Model: Citroën C8 2.2 HDi (source vehicle). Compatible With: Citroën C‑Crosser, Citroën C5, Peugeot 4007, Peugeot 807 And Other 2.2 HDi Stellantis Applications
• Product Codes: 044515025
• Other Numbers: 9659228880, 1980J8, 1980EF, 44515025

Condition And Origin

Set removed from a Citroën C8 2.2 HDi 125 kW with 128,000 km. At the time of removal the vehicle started reliably in cold conditions, showed no visible exhaust smoke and had a clean DPF. The injectors were operating correctly in the donor vehicle.

Installation Recommendations

• Relieve fuel system pressure and disconnect the battery before starting work.
• Carefully remove the fuel rail and injectors; avoid contaminating the common-rail system.
• Always fit new injector O‑rings and sealing washers/copper crush washers when installing injectors.
• Clean injector bores and rails; ensure sealing surfaces are free of debris to prevent leaks.
• Use correct torque values for rail and injector hold‑down bolts (refer to factory workshop manual for exact figures).
• After installation, prime the fuel system and check for leaks. Start the engine and observe for leaks, rough running or fault codes.
• In many PSA common‑rail systems an injector adaptation/calibration with a diagnostic tool (DiagBox or equivalent) may be required to restore optimal fueling and idle quality. If available, perform injector coding/adaptation after installation.
• For best results, have installation performed or checked by a qualified technician familiar with Bosch common‑rail systems.

Why Injectors Commonly Fail

• Contaminated Fuel: Particles and deposits from poor fuel or a degraded fuel filter cause clogging and wear.
• Wear And Tear: High mileage and repeated thermal/corrosive stress reduce spray quality and sealing.
• Fuel System Issues: Faulty high‑pressure pumps or excessive return flow can overload injectors.
• Electrical Problems: Connector corrosion, wiring faults or driver issues in the ECU may lead to misfiring.
• Excessive Soot Or DPF Backpressure: Poor combustion and DPF problems increase contaminant load and stress the injectors.

Typical Symptoms Of Failing Injectors

• Rough Idle And Misfires
• Increased Fuel Consumption
• Hard Cold Starts Or No Start Condition
• Visible Smoke Under Acceleration
• Loss Of Power And Hesitation
• Engine Fault Codes Related To Misfire Or Injector Circuit

Notes For Buyers

This is a used set of Bosch injectors removed from a running Citroën C8 with 128,000 km. Part numbers listed above are widely used when searching for compatibility. Suitable for mechanics and experienced DIY customers comfortable with diesel fuel system work. Replace all seals during installation and consider injector adaptation for precise fueling.

Product Overview

Replacement instrument cluster (speedometer/odometer) for Citroën C1 and Peugeot 107. This genuine used unit carries OEM identification and multiple cross-reference numbers, making it a practical choice for mechanics and experienced DIYers looking for an immediate replacement to restore vehicle instrumentation. Ideal for vehicles showing faults such as dead gauges, intermittent backlighting, or erratic speed readings where the cluster is the suspected cause.

Benefits

• Direct fit for Citroën C1 / Peugeot 107 instrument panel housings and mounting points.
• OEM compatibility reduces installation time and ensures correct connector fitment.
• Good option when replacement of individual stepper motors or circuit repairs is not desired.

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: Citroën C1; Peugeot 107
• Product Codes: 83800-0H012-A
• Other Numbers: 6105F9, 6103CF, 6103AT
• Mileage On Unit: Approximately 128,000 km

How It Is Replaced

Typical replacement steps for a competent mechanic or experienced DIYer:

1. Disconnect the negative terminal of the battery before starting to avoid short circuits and to protect vehicle electronics.
2. Remove surrounding trim panels and bezel carefully to avoid breaking clips.
3. Unscrew the retaining screws securing the instrument cluster and gently pull the unit forward.
4. Unplug electrical connectors (take care with locking tabs) and remove the old cluster.
5. Install the replacement unit by reversing the removal procedure, reconnecting connectors, re-seating the cluster and refitting trim.
6. Reconnect the battery and verify all functions: speedometer, odometer, indicator lights, backlighting and warning lamps.

Note: Depending on vehicle specification and equipment, some functions or settings may require basic configuration or adaptation via PSA diagnostic tools (e.g., DiagBox/Lexia) to restore features such as trip settings or illumination levels.

Installation Recommendations

• Always disconnect the battery before removing the instrument cluster.
• Work on a clean, static-free surface and avoid touching circuit boards or connectors unnecessarily.
• Use proper trim tools to prevent damage to dash panels and clips.
• Check connector pins for corrosion or bent contacts before installation.
• After installation, run a full systems check: gauges, warning lights, illumination, and switch functions.
• If any functionality is missing after fitting, consider professional diagnostic equipment for configuration.

Why This Part Fails

Common failure causes for instrument clusters include:

• Age and Wear: Stepper motors used to drive needles can wear out or lose torque, causing stuck or jumping gauges.
• Cold/Heat Cycling and Vibration: Repeated thermal stress and vibration can cause solder joints or surface-mount components to crack.
• Moisture Ingress: Condensation or leaks can corrode connectors and circuit traces, leading to intermittent faults or total failure.
• Electrical Surges: Voltage spikes from charging system faults or jump-starts can damage illumination circuits or the cluster electronics.

Suitability And Notes

This unit is suitable for direct replacement on compatible Citroën C1 and Peugeot 107 vehicles that use the referenced part numbers. Because the mileage displayed on the cluster reflects the unit’s internal odometer reading, vehicle owners and professionals should be aware of local legal requirements regarding odometer replacement or disclosure.

Purchase Advice

For mechanics and experienced DIYers seeking a time-efficient solution, this OEM instrument cluster is a practical option. Inspect connectors and functionality immediately after installation and keep records of the mileage change if required by local regulations.
