Hi,

I have a Passat 1.8T SE with Climate Control, AEB engine. There are other threads on Air Conditioning and Climate Control, 'Steamy windows', one of which mentions the appalling din mine makes when Auto is selected. Makes the car a real head turner!! The noise is not present when Econ is selected. CC still functions in the car, cools and heats!
My questions are:
1. which part of the Climate Control system is causing the noise?
2. Is it an expensive piece of kit?
3. Is it a DIY type job to replace the offending item, or a garage/specialist job? (I assume the system would need to be re-gassed)

Thanks in anticipation........
