Is it normal for my Audi A1 to make a loud clicking noise when I turn the AC on?

I recently purchased a new Audi A1 and I've noticed that when I turn the AC on, there is a loud clicking noise coming from the engine. Is this normal or should I have it checked out?

Yes, this is a common issue in many Audi A1 models and it is usually caused by a faulty AC compressor clutch. It's best to have it checked out by a mechanic to avoid any further damage to the engine.
