Hi Guys

I've a 2011 1.4 TSi (brill engine) Elegance + estate with Climate Control.

Earlier this year I had to have the ac condenser replaced (by an indie garage; needs must!)

Air conditioning has worked fine ever since - but here's the 'but' !

After a while it (maybe an hour or so; sometimes less) it stops working; it doesn't appear to be blowing air. 

Switch it off for 10 minutes or so and it starts working again/blowing cold/cool air.

Have made a mental note to look closer at the problem when I have time.

 

Separate issue: 

Today I pulled out the LH Fog/DLR pod in the front bumper to replace a blown bulb.

When releasing and pulling out the lighting fixture - something else came out with it!!

See attached photo. (it's the small black angled item dangling on the end of the wiring loom to the left hand side of the pic)

It looks like it might be a temperature sensor of some sort - and is part of the same wiring loom that supplies the lighting fixture.

It's a black plastic right angled fitting about 7 to 10 mm diameter.  At the end are some moulded 'prongs' and ridges that suggest it's a push fit into a round opening.  Within the 3 'prongs' is a smaller black bulbous looking feature - which might suggest it's a thermistor or other sensor (am trying to make a semi intelligent stab at what it might be - but could be wrong !!!) 

 

WHAT IS IT ?  AND WHERE DOES IT GO ?

 

Could this be the source of the climate control problem - having been removed/dislodged by the guys who replaced the ac condenser earlier, and inadvertently not put it back when reassembling the front end of the car.

 

Have looked closely and stretched it to the limits of its made up length within the condenser/radiator/front bumper area and can't find any obvious mounting hole or point !

 

Help please to establish where I should refit it.

It is the outside air temperature sensor. Feel around and you should find where it and the cable support plug in.

It's supposed to be attached to a bracket behind the lower grill

To all 3 of the above - belated thanks to the 3 of you; it was only earlier this Sunday afternoon that I was able to follow up on your suggestions/information.

It was indeed the outside temperature sensor - and on a closer inspection there is a small bracket about 1/4 to 1/3rd distance along the front of the condenser and radiator, below and partly hidden by the LH high pressure headlamp washer hose; this small bracket has a hole exactly the correct size to take my 'right angled' dangly thing ( :clap:  ).

Thanks for your help guys.

While clearing the leaves away from in front of the radiator. I found mine dangling as well. Notice a metal bracket with a hole in it. Attempted to insert the sensor but no overt 'click' as I hoped for. Will keep an eye on it coming loose again.

ambient temp sensor. it is normal to not hold properly. Mine was held in place by cable tides
