    Does anyone know what this disconnected plug is at the RHS of the engine bay zipped tied up. It's a 4 pin plug with only 3 wires. Brown,Blue and Black. No faults with the car. Will investigate more tomorrow.

    Something to do with your aircon [or climate control if your car has it]. :\\\\ The black 'cap' above it is one of the drain or fill valves for it.

    Does yours work well? Can you trace where the wires run to? =|

    Yes no issues with Climate Control or any faults. Must be an auxiliary connection for something not fitted?

    A pre-heater connector? Alarm sounded box?

    Check to see if the MAF is still connected?
