Like many other 964 owners, I have been plagued with a subtle but steady fuel odor in the cabin, if the car has been left with the windows up overnight or for more than a couple of hours. It is more noticeable in the summer, but still noticeable in the winter.
I tried the recommended "fixes": (1) new gas cap; (2) new fuel filler neck; and (3) having the carpet in the trunk professionally steam cleaned, all to no avail.

I just tried the other fix, which I heard about here on Rennlist, replacing the charcoal air cannister that connects to the gas tank's breather line.

It's only been a couple of days, but it appears to have worked! I left the car with the windows up for three days, opened the door this morning, and noticed no fuel smell!

I'll report back in a couple of weeks with more definitive results.

In the interim, the information is as follows: charcoal air cannister; located above the left rear wheel; part number #993.201.221.01. My local Porsche dealer charged $56.64 for the part, $127.50 in labor, and $2.54 in tax, for a total of $186.68 (not counting the PCA discount).

Reason #1 not to top of during fueling!

So do I, and the dealer had been unable to solve the problem. Gas cap has been replaced twice. Most noticeable under hard acceleration in lower gears.

Anir

Anyone else have this problem?

I have a constant smell in my cabon... I would love to get rid / reduce it but not sure where it is coming from.

My local dealership checked everything and still can`t pinpoint exactly where the cabin smell originates from. ie: pressure checked the gas tank etc etc etc. We changed the carbon can filter thingy just to be safe and still nooooooooooo luck

PLEASE SOMEONE HELP ME PLEASE.

Gents. I know this is an old thread but I'm sort of happy in a way to find out that I'm not alone. Did any of you find a long term solutuion to removing unwanted exhaust, gas, musty odors in your 993's? I sent Jim Pasha over at Excellence Magazine that very question and he doesn't feel there's an easy solution - sort of an idiosyncracy that's plagued air-cooled cars. With the cabin so close to a hot rear firewall any oil leak will permeate into the cabin. And others say that the heat makes the adhesives in the cabin smell. I also understand that the front firewall isn't air tight, therefore the spare tire rubber smell can also make it into the cabin. I'd like to know if there's a longer term solution and alternative to Febreze. Thanks

I have had the same problem since purchasing my car last year. It has only happened twice when filling my car with gas. On the first occasion I opened the trunk and let it air out for a few days (pulled fuse #11 to stop interior lights from draining the battery). On the second occasion I pulled out the carpeting and spare tire and actually noticed a little gas in the trunk but could not identify the source of the leak. I cleaned that out and let it air out once again. If I keep the tank no higher than 3/4 full there is no leak or smell.

Just last night I filled the tank again but with the pump handle reversed. This morning no gas smell is noted in the trunk. I will probably try some of the other remedies suggested here and keep my fingerrs crossed. I will definitely replace the fuel filler neck as it does not have that little flapper that originally came with the car. A permanent solution would be great.

Nice to hear from a fellow Canuck, Bret. I'm hoping J-McDonald will reply - in his last post post awhile ago he replaced a carbon cannister which was helping and was going to update us.

It's a good thing they're such great cars to drive - these things should've been ironed out on what was once a car norh of $80,0000 US new.

Hey I'm just glad the Germans weren't making such great machines 65 years ago, otherwise none of us would be typing in English LOL.

johnnypiedras

have smell in trunk, had it for years, finally putting on a charcoal cannister. I i did read on this site the smell can be contributed to mold.

I had the same problem. Reason was loose rubber tube between tank and vapour tank.

I was going to mention that... I saw a thread the other day on it.
