When was your A/c system last properly serviced ??? Does the air conditioning work when you are driving and seem to stop working when you are stationary ?

It Was recharged last June, and im just noticed that if Im driving more than 30min stop blowing cold air, then if I switch off and on again, working for 10-15 min.
And If I turn the AC maximum speed than the water leaking under the car, i know it is a condensation but its a huge .

If I were you I would get an Air conditioning specialist ( definatly not Halfords or Kwik Fit ) to properly service your a/c system , ask whoever does it to triple vac it with Oxygen free nitrogen , it sounds like your accumulator drier might be freezing up due to excessive moisture . Where abouts in the country are you ?

I had a similar issue about 6 months ago and it was the receiver dryer that had become clogged up. OEM part (8E0820193J) was megabucks so got one from states 'Comfortauto' https://www.ebay.co.uk/itm/332211968564 ... Tags=bu=bu for $26.99 plus $36.00 freight $62.99 total which was about £50 - not a bad saving! The killer is the labour which took 3.5 hours. The air-con is now all working OK, nice and cold as it should be.

I hope they can sorted without fitting new drier. This is how is looks the pipe. Frost. They said they try to recharge the system and we will see how it is work.

Looks like the pipe could be blocked by a clogged up drier. If you get a new drier fitted you'll have to pay for fresh re-charge anyway. So if it turns out to be the drier and you get one fitted you'll end up having to paying twice for a recharge! Try to get a dedicated air-con specialist to test it rather than a dealer...
