Unknown cable coming from inside car to under bonnet

Does anyone happen to know what this cable might be for?
I've just noticed that it's sitting there doing nothing!

It looks like a bonnet pull but the bonnet pull already works perfectly.



I've circled where it comes into the engine bay

Thats for the heater blower matey there shud be two pipes that go into the central area of the firewall (theyll be one ontop of the other) on them there will be a plastic sort of adjuster that this wire clips to, i think its for adjusting the amount of heat that comes out the blower

Hope that helps

Actually mate from ur picture it looks like ur missing the control valve actually, where the top pipe is of two u have a peice of wat looks like copper pipe connecting two pipes, thats where the control valve should be

Chipster - thanks for the response.
I've been getting no heat out my blowers - this will be why!!

So, I need one of these?

That is the part you need, you will need to find a metal clip which holds the cable onto it.

If the copper pipe someone has fitted is letting water through you should be getting hot air in the car as the valve stops water getting past in to the cabin.
Just to check, you only get hot air from the vents on top of the dash and 2 small vents at the side or the foot wells, you only get cold air from the main side vents you can open.

Cheaper one here as VW heritage are always expensive…..
