hi guys I have a 2007 Audi s3 and the a/c is not working, both the fans spin when the econ button is switched off however I don't get any cold air, no fault codes stored and fresh gas in system, revs do fluctuate when econ button is pressed which makes me think something is happening with the compressor, would rather be able to diagnose then guess at the compressor. could it be an internal fault with the compressor not cooling the air?
