Think that's the one you want mate.
Pete will hopefully confirm but I'm confident it is.

Holy crap well I aint paying that :D

Cheers mate

Could try giving it a good clean up with some white spirits and the connector in case it's just gummed up or maybe had overspray on it.

Yeh Im going to have too, I generally like to replace faulty items with new items (whether they scrub up or not) and I remember someone saying they got one for £3 off ebay. Which seems alot fairer than £45 lol. Also I cant be asked removing the bumper just to clean this plug. It doesnt bother me it just means 'Auto Function' is ineffective which I dont use anyway :D

Something to look out for and replace at next bumper removal.

It is mounted on the N/S fog light bracket.

Don't worry, they are nla from xpart so you won't need to pay £45.

Contact http://www.readerair.co.uk/automotive%20home.html, they are an agent Diavia, which the Climate Control and sensors are made by.
The sensor IRC is £35, Call them, say its for a MG ZS they should know what your on about.
I got a new sensor from them ages ago.

I've got the part number somewhere for the Reader Air one, it's where I got mine, you'll need to swap the plug as it doesn't match the zs.
