I've read there's a mold spray you can put into the cabin filter and run the A/C for a while to run in through.

Suggestion

This means that less humidity is sitting in the system and less odors the next time you start the car and use the AC.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

20 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

It disappears after abour 30-60 seconds as the air keeps blowing throught the system. Is there some air filter that can get moldy? Thanks!

POST 2Original post

Also make sure your AC condensation drain is clear, and properly draining out the bottom of your car. Yes, your car has a cabin air filter: http://www.suncoastparts.com/product...ode=996AirFuel And you may actually have a bigger issue with actual mold in the HVAC system. This may require a professional cleaning process.

POST 3Original post

My car has just started to do this also, only for the first 5 secs or so. I've read there's a mold spray you can put into the cabin filter and run the A/C for a while to run in through. No HTwo O where would you find the AC condenser to check if it's clear?

POST 4Original post

I have seen this happening in quite new cars like audi a4 and lexus as well. I always wondered what got this started, but once it is there, it stays.. only 2 or 3 first minutes but not pleasant.

POST 5Original post

Try this: When you arrive to destination, don't turn the engine off when the AC is "on". Turn the AC "off" first, but keep the fan blowing air for 30 seconds while the AC is off, then shut the engine. You will feel some humidity on the air vents in the dash. This means that less humidity is sitting in the system and less odors the next time you start the car and use the AC.

Aspen, not exactly sure, but this topic has been cover here on Rennlist before, complete with diagrams. Try searching. Sorry. For example, on the 986:

POST 7Original post

yukk... I would hate that my car smells like oil and gas mixed - its that "old Porsche" smell - seems to me if you spritz a little fuel oil mix into the vents you could try and get some of that

POST 8Original post

My car smells, but only when I am in it. (maybe its me)

POST 9 / ORIGINAL POSTEROriginal post

Quotes source post: 8695756

Excellent; I will try that out. It goes away in about 30 seconds - so that makes sense. I am still a relatively new P-car owner (3 months?); but also have a CPO on the car .... so if its bad I will go back to the dealership. Thanks!

Can someone go look at the part number on the cover that goes over the cabin filter. I cannot believe mine is missing.

POST 16Original post

I thought mine was missing too. There isn't a cover over the cabin filter

Hilarious, well that's good to know. Thanks.

POST 18 / ORIGINAL POSTEROriginal post

The good news is turning off the AC for 30 seconds works to keep out the stinky smell. But I still want to figure out why its happening. Awesome advice so far guys, thanks!

POST 19Original post

Quotes source post: 8702014

The heater core is downstream of/from the A/C evaporator so unless you recirculate inordinately HEATED (uncomfortable, that) cabin airflow..... Besides which in our cars the heater core is ALWAYS at engine coolant temperature, no modulation or shut off to coolant flow.

POST 20Original post

so I can't believe no one has mentioned this yet... http://www.detailersdomain.com/1Z-ei...aner_p_78.html I've been through a couple cans in my 325 and my 944. YES it works!
