Climate control cutting out

[Charcoal007]

I have a 2010 CC.

Recently I on a very hot 40 C day the air conditioning stopped working.

The fan couldn't be set to more than 2.

There was also a strange low warning tone sounding.

Today when the outside air temp dropped to 30 C the air con was back to normal. Fan was able to be set to maximum.

Any thoughts on the issue ?

Hi if interested I have a climate control that would suit your car. If interested call me on 0402699671 Sam

No thanks.

It's working fine now in less extreme conditions. Not very helpful in extreme hot weather.

I suspect there is some over temp sensor or engine control system that was causing the issue when the outside air temp was near 40 deg.

Personally have not seen that issue before with my CC.

You'll need to get your car scanned with VCDS to see what fault codes would be stored in the climate control system. That should give you a good indication as to where to start
