Why is my Audi A6 making a clicking noise when I turn the AC on?

Recently, whenever I turn on my Audi A6's AC, it starts making a clicking noise. It seems to be coming from under the hood. What could be causing this and how can I fix it?

This could be a sign of a faulty AC compressor or a dirty AC blower motor. I recommend taking your car to a trusted mechanic for a diagnosis and necessary repairs.

I had the same issue with my Audi A6. It turned out to be a loose AC fan belt. I tightened it myself and the noise went away. Make sure to check all of your AC components, including the belt, for any signs of wear or damage.

I had a similar problem with my Audi A6 and it was due to a clogged AC filter. When was the last time you had your AC filter replaced? I suggest checking and replacing it if necessary.
