Just recently, my
2006 Cayman S
with about 21K miles on it has started to produce fuel fumes/smell in the car. It is most noticeable when the car sits for a while with the windows closed. Level of the fuel tank does not seem to have any impact on this. Once the windows/doors are open, the smell dissipates quickly, and when driven, even with the windows up, I really can't smell it. Like i said, most noticeable when the car has been closed up for a while. It is not super strong, but definitely noticeable. I have not seen any fuel drips/steaks outside of the car. I have also not noticed any strong fumes outside of the car (ie gas cap, wheel wheels, etc....). Pretty puzzled by this and am looking for trouble shooting advice. Did a search on this site, and really couldn't find any indication that this has been a problem on other cars.
Thanks in advance.
Maybe your fuel vapor trap off your gas tank is plugged?
I'd pull the engine cover and do a really methodical search for a fuel line leak. If that's beyond your skill set, find a real good independent
Porsche
shop and let them give it a going over.:cheers:
I'd start investigation immediately. Fuel smell in any car is not good! If there is a leak it is usually small, evaporates quickly and you can't identify it by just guessing. Obviously, when you drive with the engine behind you, there is no smell. You cannot see drip either. It is a serious fire hazard!!!
The car of a friend of mine with rear engine burned entirely. They were in the car driving, not knowing that the fire has already started in the engine compartment but was not visible because of the air flow. The moment they stopped at an intersection, the car burst in flames. Thanks God they quickly escaped with minor burns on him but until the fire department came the car was gone.
All good inputs. How would I access/examine the fuel vapor trap? Internet google searches have not come up with much. I plan to tear into it tomorrow.
Thanks.
Update. i spent the past weekend ripping into the car, and could find no evidence of a fuel leak. Just to be safe, i took it to my mechanic this morning, and he too was unable to find evidence of a fuel leak. He did say that it could be possible that I am smelling something associated with the HVAC, but they would have to rip apart the dash to get at that. I decided that with no fuel leaks discovered, I'll drive the car a little more and see if I can pin it on the HVAC. Then, we'll see about digging into that.
