Metzger Control Unit – Heating & Ventilation

The Metzger Control Unit (Model 0917023) is the central electronic component that governs the interior climate of Peugeot vehicles equipped with automatic climate control. Designed for precision, reliability and seamless integration, this unit manages heating, ventilation and fan speed to deliver a comfortable cabin environment under all driving conditions.

Key Functionalities

• Heating Regulation: Controls the blower motor resistor and heater core flow to maintain desired temperature setpoints.
• Ventilation Management: Adjusts fan speed, airflow direction and recirculation modes automatically based on cabin sensors.
• Climate Control Integration: Communicates with the vehicle’s central climate control module via CAN bus to synchronize temperature, humidity and air quality settings.
• Diagnostic Capability: Provides fault codes for heater core, blower motor and sensor failures, enabling quick troubleshooting.

Vehicle Compatibility

The unit is engineered specifically for the Peugeot 308 family, including:

• Peugeot 308 I (1.4L & 1.6L)
• Peugeot 308 CC (Coupé Convertible)
• Peugeot 308 SW (Station Wagon) – both 7‑door and 5‑door variants
• Citroën models sharing the same climate control architecture

It fits all chassis codes that use the standard 8FR/8FS or 9HD/9HG/9HR body styles, ensuring a perfect match for factory-installed systems.

Installation Overview

1. Disconnect Battery: For safety, remove the negative terminal before working on electrical components.
2. Remove Existing Unit: Detach the old control unit from its mounting bracket and disconnect all wiring harnesses. Keep track of connector orientation.
3. Mount New Unit: Secure the Metzger Control Unit in place using the supplied brackets and fasteners.
4. Reconnect Wiring: Plug in the harnesses, ensuring each pin aligns with its corresponding terminal. Verify polarity and continuity.
5. Re‑connect Battery: Restore power and perform a quick system check to confirm proper communication with the climate control module.
