Doesn't seem to work 100%. It's intermittent. For example yesterday morning i drove about 10 miles and it suddenly worked and today work perfectly all day with no problems. When it does work the cooling is perfect. Any ideas? There are no fault codes.

Exactly the same as mine last summer, now it doesn't blow cold at all.

Going to give this a try: http://briskoda.net/forums/topic/196338-air-con-not-working/, and then maybe a re-gas...

There is a compressor failure.
