Usually, you will get the moldy smell after a winter. What happens is all the leafs and dirt get into your fresh air intake and into the evaporator AC drain pipe or Sunroof drain pipe and claugh it up. So the water from the rain doesnt have a place to escape and it goes down to your evaporator box and just sits there. Then everytime you turn the AC/heat on – you smell it.
I have seen a few complaint on this forum about their musty/moldy smell coming out of the air vents. So I figure I share some resources about this issue. Every car on the market has the same problem. Not only porsche. But there is solution.
1 – First, change your interior filter. I wrote a post about that: Air Cabin Filter replacement DIY
2 – Clean your Evaporator drain pipes and sunroof drain pipes (I have not done that myself yet so you have to check the dealer to do that for you). Usually its hidden inside of the right fender well with a rubber flap or in a star shape (at leats on AUDIs and Lincolns). It may be just a rubber hose. Pull the fender whel and look around. I will try to find some pics or do a DIY someday.
3 – Cheapest way to get the smell out would be to spray some Lysol sanitizer into the air intake (in the engine bay) couple of times for couple of days. I have heard of that solution couple of times.
4 – If that doesnt help – you have to go and get a product called Frigi-clean and Frigi-fresh

a) Frigi FRESH (no drilling):
Raise the hood, start the car, open the driver side window and turn on the A/C. Verify rear passenger vent is open. Select Fresh Air, Max Cool (lowest temp) and Mode to Center Vent. Once air from center vent is cold to touch, spray Frigi-Fresh on the A/C air intake (below windshield) until you can smell it coming out of the center vent. Then change mode to Foot Warmer, spray Frigi-Fresh, change mode to Windshield Defroster and spray Frigi-Fresh. Do a similar process in Max Heat (highest temp). Repeat process as needed. I spray less Frigi-Fresh while in Max Heat.
or
When you spray into the intake duct below the windshield you are just spraying to the top of the cabin filter, it may be more effective if either you a. removed the filter. or b. remove the filter and spray from that spot where you remove the filter behind the glove box.
b)
