Secret air conditioning sequence? R36 2008

[Screwdriverone]

Hi all.

With warmer weather on the way, I wanted to ask if anyone knows the special secret aircon sequence that actually makes the air come out cold when you start the car and set the aircon to high when the car has been in the sun and is hot?

It often takes about 5-10 mins of driving before cold air comes out of the vents. it even stops blowing cold periodically after it starts to cool, as if the compressor is cycling off for some reason.

I have tried turning off the climate control completely and cycling the a.c. on and off and even directing manually to the face vents and putting it on 16deg (LO) and nothing seems consistently workable.

is there a cabin sensor fault or some other issue? Or is it simply the asthmatic euro style aircon?

gas is not the issue as it was regassed in Jan of this year and DOES get cold, although not consistently enough on start up when the car is hot.

Any ideas? No errors on the system through OBD2.

Cheers,

Chris
