This week has been a mare for my 1.9TDI 130. Tuesday saw the end of the alternator clutch pulley so went to see the audi indy wednesday morning and they confirmed this but cant get me in till a week this saturday. Is it ok to keep driving i asked and they said yeah it'll just be noisy and may feel notchy in the steering. This evenings commute home from work, the air con doesnt work, this morning it worked fine, nice and cold but now its not getting cold at all. When i press the ECON button i can hear the tempo of air change etc but no cold air. Can this be related to the faulty alternator pulley, the systems running on the same belt and its simply slipping on the air con compressor? (im no mechanic by any stretch of the imagination.) Help please guys.
