Reported fix

I had the same in previous 993 soon after purchase, turned out the toe in adjustment cams were reversed when they replaced clutch as condition of sale. Toe in was way off, they gave me free alignment and rear tires and no more problems.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Do you guys get this soot on your rear bumper? I get this much after approx 2 to 3 hours of driving. I used to get the same thing on my 993 when I had it. (I'd like to think its from the exhaust, but I've seen a post before that it was from the tires due to the rears being toed in??)

POST 2Original post

I don't have it. You may want to clean up the inside of the tail pipe and check for exhaust leak. Also, is your car up to date on service? Is it running rich for any reason? I doubt that's from the tires.

POST 3Original post

Every car, truck or any other object that is moves along the road on rubber tires gets it, whether the owner notices or not. This is dust from the tires. exhaust as well as road film. The lighter the car color, the more you will notice it. The more polished your car, the more you will notice it as a fine dust. If your car doesn't have a smooth finish on it, it may accumulate in clumps. Obviosly, if you clean your car often or dust it regularly, you may think you are amune to this.

POST 5Original post

I get it and let me tell you, it pisses me off royally. Imagine how I get when a bird poops on my Cab...

POST 7 / ORIGINAL POSTEROriginal post

Ok, at least I'm not as worried now. I was starting to think that it could be the oil seperator that everyone is talking about. Like I said, I get the same soot on my 993. Thanks!!

POST 9Original post

I had the same in previous 993 soon after purchase, turned out the toe in adjustment cams were reversed when they replaced clutch as condition of sale. Toe in was way off, they gave me free alignment and rear tires and no more problems. It seems not obviously happening on my 996 C4

POST 11Original post

porsche = great handling car...$90,000 z- rated tires = good grip...$800 quick detailer = good looking car...$5 coming home to find tire dust on your back bumper from ripping around in the porsche all day = PRICELESS

POST 12Original post

Looks quite normal. Get a california duster...works great for getting the dust off.
