As the title suggests, does anyone know what this hose is for?
Please look at the picture attatched, any information would be much appreciated!

Thanks

i think its an ambient air temp sensor for the climate control. i always see this on EA/B/D that have climate.

ok had a look in the schematics and it is is definetly a cabin sensor, which is conected to the cabin air sniffer motor. the motor should have a red/green wire off it.

AFAIK, it measures the temperature of the cabin. Mounted to the facia panel, is a small sensor. When the hose is connected, the motor causes air to flow over the sensor, telling the climate control system what the cabin temp is. The climate should work without it being connected, however, the temps might not me accurate, or it might take longer to reach the desired temp.

It actually uses engine vacuum to draw air across the sensor. To check the operation of the vacuum line, hold a light piece of paper over the cabin sensor opening while the engine is running. The paper should be drawn against the panel.

As advised above, it is part of the cabin temperature control.
It is comprised of two parts:-
1. The temperature sensor which is mounted just behind the slots to the left of the trip computer,
2. A small fan and electric motor mounted beside the instrument cluster. The hose is the air intake for the fan.

The climate control runs the fan which draws its air through the tube and the air enters via the slots and flows over the sensor (it does not use vacuum from the engine).
It provides the in-cabin tempurature to the Climate control.

The Climate control uses this to work out whether to run heating or cooling and how much of each.

It is critical to the Climate control operation.
