Hi guys Picked up my new black edition in march and I've been loving it. However, and I don't know if this is just a coincidence but with the good weather I turned my air con on for the first time yesterday and I noticed a weird buzzing noise. Thought it was just the radio so turned it off yet noise was still there. Journey yesterday with no air con and no noise, today with air con on noise back. Anyone know what this is and is it easily fixed or do I need to take it to dealership?
