Random Heat On Automatic Climate Control Setting

[willy_manily]

Hi there,

So just picked up my new "used" E70 X5 and i love the car... except the Automatic setting on my climate control.

Basically, it will work perfectly fine and distribute 22-23 degree celsius air around my cabin but randomly it will increase fan speed to almost full and then blow hot air into the cabin out of some vents. The only way to stop this is turning it back to manual mode and waiting a few mins before switching back to Auto again.

Has anybody experienced this? It is such a strange issue and I thought that potentially the AC compressor was shitting off but simply turning down the fan speed (aka switching it off auto) seems to fix the problem.

Any input/testing would be awesome!
