When I start the car, the climate control does not seem to work. However, after a few minutes, it suddenly wakes up and produces lots of cold air. I had it re-gassed today, and when the mechanic had finished he tried to measure the temperature of the air, but again it did not produce any cooling. Then after about five minutes of tick over, the climate control fans started up and again plenty of cold air. I have no chance to do a VCDS scan at the moment. Just hoping someone would suggest what may be wrong. The mechanic thought it might be a temperature sensor. Any suggestions very welcome. Thanks in advance.
