Recently bought pre-owed C207 with 20K miles. Upon startup, AC got moldy smell, not too strong but it certainly unpleasant. Should I get AC system cleaned and filter replaced? What would it typically cost at MB dealer?

My air con filter was recently replaced circa Aust$90 from memory.

Get the more expensive cabin filter with charcoal.
BEFORE installing the new filter, I would 'fog' some micro-ban into the intake with the fan set low.
Don't go crazy, 3-6 fog sprays.
Sniff around the carpet for water / mold smell. The car may have had some water intrusion, rain, high water, clogged a/c drain, etc.

Change the cabin filter with an activated charcoal one on a regular basis and all should be well.
