Interesting. Good outcome. What year is your 997? Any indication from the dealer what years P used the adhesive in question?

 

My 25 year old 911 had the "drivepur" treatment done by Metropolitan detail in Seattle area. Totally took off all the old car, "mold" smell. Not sure if that will work for your car but sure worth a try if this recent change does not do the trick.

 

pollen filter/ spray won't do anything to fix the problem. you need to use the evap core treatment and that will fix the problem.

 

In any case, it is always a good idea to turn the AC off 2-to-3 miles before the engine is shut for a long time. During those last 2-to-3 miles raise the fan to dry up the plumbing.

 

Great news that you were able to get it fixed! That's very annoying. That should be helpful to a lot of other people. What year is the car? Was this a new type heater core integrated for certain years and then replaced with one that worked better?

Mine is a 2006 - I pick up the car tomorrow and will get the full details. I'll post back what I find.

 

Picked up the car today - no smell with the AC on. Porsche has a TSB out on this now, my SA wouldn't give the #, he said he is not allowed to and he wasn't sure how long it had been out when I asked him.

Here is the info from the receipt.

Replaced the A/C Heat Exchange (997-572-129-00)
Gasket, Heat Exc (997-572-913-00)
2 gallons of Antifreeze 3.7 (000-043-301-05)

"Musty odors from air cond when first swiched on. If equipped remove microfilter before treatment. Technician checked found the heater core has an adhesive on it that is smelling. Porsche has a tech bulletin to replace it with a new updated heater core. Technician replaced heater core."

 

Try Einszett Klima Air. It worked well for me.

 

Congratulations and thanks for the update. I hope it stays. Your post will probably help many.

We do some odor removal on restoration vehicles and the one thing that will kill the smell is to have an ozone treatment. Ozone kills the mold and spores instead of masking them. The nice part about the ozone is that it will filter throughout your heating and cooling system to eradicate the mold and mildew smell. Vehicle must be vapor cleaned and them have the ozone circulate inside the cabin for 20 to 30 minutes. This should be your answer. Definately replace cabin filter after treatment to ensure you remove all the odor causing issues.

 

I hope so on both counts.

 

Well bad news - the AC smell comes back when first turned on. The smell will dissipate after a minute or two but it shouldn't be smelling at all.

Pretty disgusting both in terms of the smell and the fact that it is back.

What a PITA.

I'm going to get in touch with the dealer again and get it over there. I've got too much time invested in this problem.

 

I also talked to my dealer regarding this issue today. I am in Taiwan and We are more humid then anywhere else. My cayman s, 997C2, and 997TT. All have this problem. It's really a bad feeling during a cold start in the morning. They said after I am on the way home I turn on the ECO and let it drive for 5 ~ 10 minutes. They said this usually fixes the smell problem. I will give it a try and let you folks know. This is a very embarrassment problem when you are about to ride with a girl. ;o

 

Just a caution: The rear view mirror hanging deodorizers mentioned earlier in the thread are deadly to the car interior. I had one brush against the dash in my Subie and it damaged the plastics badly where it made contact. Beware.

 

Can you please tell me what year/model this fix is for? And is it a "recall" type thing?

My 09 Carrera 997.2 has less than 10K miles, but while its having an oil change this weekend, I'd like any recalls done at the same time too....
