Mk7 Heating/Air Con mind of its own

[Carracer12]

Hi,

So I made a thread about this a while ago, and got some good suggestions but I now have more information.

I can turn on my heating or air conditioning and it will work fine for anywhere between 1 and 5 minutes but then there's a clunk sound from inside the dash and the air conditioning becomes hot air. It often happens as I accelerate but not always. Heating is similar where it'll just decide to go cold after a while.

With the hot weather the UK's been having recently, no A/C isn't much fun so I'd like to get this sorted if possible!

Thanks!

I have exactly the same problem and don't know what to do with it. Any suggestions?

Usually that's the aircon having low pressure, and switching itself off to prevent damage to the compressor. I'm guessing you have a small leak somewhere.

Thank you, will check the pressure.
