Hey I just noticed mine does this. Something like a heartbeat rhythm only audible at idle with aircon on. No sound with aircon off. Did you remedy yours?

What are the main things to look out for an a used 523? Car drives generally ok, no funny noises, gear shifts are smooth, but I noticed oil leaks at the front of the engine near the oil filter housing
