Did anyone/ Karlbar actually get to the bottom of this? Just had thermostat and the engine temp sensor changed afew weeks ago and fault started soon after. Intermittent blowing hot even on Low/cool!
This is fairly common. It's happened with mine on and off for a while. A scan is showing a faulty sensor in the climate system. Hopefully getting this sorted in the next few weeks so I will post details of the fix. My display on the climate panel now has a shadow image of an impeller behind the temperature display which is new.
The system still cycles fine between the various vents when you 'exercise' them manually however it's not blowing as cold as it should. The compressor was recently recharged and showing no leaks.

Behaved ever since it did it the once! Will leave alone I think...
I had this with mine and it was poor connections to the flap motors under the dash. It was as simple as unplug them and plug in a few times followed by a drop of WD40 on the contacts before final reassembly.Just to update. Just had the a2 back after long term loan to daughter and it was still blowing hot. VCDS reset all codes after doing a full scan and a.c. is working again.
