Useful Information
The heater matrix is a small radiator located inside the HVAC/heater box. Hot engine coolant flows through the matrix, allowing the blower motor to push warm air into the cabin.
If heater performance is poor, it is also worth checking the coolant level, thermostat, heater control valves, coolant circulation and HVAC flap operation before replacing the matrix.
Important Compatibility Note
Please compare part number A2118300962, pipe connections, matrix dimensions and mounting points with your original unit before ordering.
Different heater and air-conditioning specifications were fitted across the W211 range, so matching the original part number is recommended.
