My 2009 Carrera S is a soot factory...it is really unbelieveable how much soot is on the inside and outside exhaust tips and rear bumper of the car after a week of driving. When I start the car up it covers my garage floor and back wall with soot it blows out of the exhaust! My car sooted up even with the stock exhaust but shows more soot now that I removed the 2 side mufflers and only use the rear muffler since the exhaust path is not as restricted. The inside of the stock mufflers is full of soot that I could dump out.

I took my car to my dealer and they kept it for a week and did a full diaognostic check out. They pulled the headers to look into the exhaust valves, did a compression check. Everythng was way in spec but they can not find out why so much soot. I also was burning around a quart of oil every 700-1000 miles. The oil burning has since tampered down to 1/4 of a quart in 700 miles.

I followed my wife in the car and had her floor it getting onto the freeway and a black puff comes out of the exhaust. I say the car is running extremely rich.

So much for the new 2009 Carrera S being a greener car...the exhaust it puts out if filthy. Porsche needs to address this issue with what I would suspect with a leaner cleaner burning ECU fuel map. However I get the feeling that Porsche could careless about this issue.

 

I have a 2009 C2 and noticed the exhaust to be sooty after a few drives. I also noticed the soot on the garage floor. I included some photos. Is this normal for a DFI engine?

Gray911, your tips look fine compared to what I am dealing with. My entire exhaust tips...outside area of the tips and rear bumper get coated in soot. I have to wash my painted garage floor out every weekend now due to the amount of soot that is coming out of my car.

I am trying to be a calm and nice as I can about this but I am beginning to wish I never got this car. The dealer and Porsche North America baiscally are jut blowng this all off because outsid eof the filthy exhaust this car puts out it runs good.

 

Hmm. 250 miles so far on mine and nothing of the sort. No soot on the garage floor and the tips are relatively clean. And I--uh--have been driving the **** out of it right out of the box. When did this problem appear? From the beginning? What octane are you guys running in Florida (don't know if this would matter???)

 

I have about 5,000 miles on mine and have experienced exactly the same behavior. I have the soot on the garage floor and I am amazed at how quickly it gets deposited. I don't sit and let the engine warm up at all, I just start and back out. My oil consumption was high also, but has started coming down in the last 1,000 miles. Just made a round trip to Dallas and back, about 450 miles, and it didn't register any oil consumption on the gage.

 

My pipes at 600 miles. This is my first p-car so I can't compare. I haven't noticed any soot on the back of the garage door or floor.

 

If you don't go out there and drive that damn thing then I'll go drive it!

250 miles? Shame Shame!!!!

 

I know. I need a roadtrip badly.

 

Mine has plenty of soot on the inside the exhaust pipes (PSE). I use a quart of oil every 1000 miles (still, since new). Porsche is replacing both sport mufflers and the exhaust tips (PSE quads) tomorrow under warranty. They have been been exhibing a lot of noise at startup that remains until they warm up (and presumably expand). The welds that provide mounting points have cracked.

 

Hey am722, I feel like having a good steak tonight and need to put some miles on the new car. Any suggestions in Houston?

 

I assume you picked it up this morning?

 

Steak? Man, the only thing worth driving down here from CA for is brisket. And it is worth it.

 

1 week, 6 days, 22 hours and 55 minutes ago. I deserve the shame. Work has me captive.

 

Well, in your defense; I'd love to have YOUR problem with driving the car! Not really the worst problem to have.

 

drive it more the soot will come. I drove 500 miles all over the Tampa area the week before. I wash my car on Sunday because the tips inside and out looked like they came off a city bus.
