Iv had my aircon re gassed , and checked for leaks etc ..
But it’s still not “ice cold”
Is there anything that might need changing like the rad ??
Thanks. Colin

Pressure sensor is a likely culprit

You need a crows foot spanner to replace it

Have you waited for the car to get up to temperature?
i know the air conditioning compressor on the mk5s has a habit of going.
When i got my mk5 gti the air con was cold as hell then it went soon after i thought this could be the case with mine but luckily i did just need a re gas but i did look into what else it could be as it happened late at night and alot of people were saying air conditioning compressor could be a problem.

Iv done hour ride home and it’s still not that cold. I’ll have a look at the above
It’s it an easy job to do ??
-
Will the air con need re gassing after fitting that ?
-
yes unfortunately it will.

No it won't
The pressure sensor sits on a non return valve or similar so when removed the gas does not escape
-
sorry i ment the full unit not just the sensor like in my previous post

The high and low side pressure sensors will throw a code in VCDS if faulty.
Other causes of less than satisfactory chilling are:
Air con pump - you will know if that's dead. It won't 'clunk' into action when you put the AC onto Auto and LO.
Blocked or leaking condenser - Blocked fins is very, very common on these cars, being the front most radiator in the sandwich of 3.
Receiver drier canister thing to the left of the radiator - Dunno what that does but apparently another potential cause.
Gas leaks - usually from a cracked condenser. Fluorescent dye is the easiest way to find leaks, or a sniffer probe.
Radiator fans - these should be seen spinning when the AC is on at idle.
And lastly, the AC on the MK5 really isn't all that anyway. Mine is fully operational and I have to drive for at least 30 mins with the windows closed before I get what I consider to be cold air out of it. It's never been 'icy' cold like a lot of other cars kick out.
