Hey guys.
I'm 3 weeks into my first ownership of a Porsche. Love it.

Got some issues though and wonder if there's any pointers round here. My car is a 997.1 Targa 4S Tip. It's only travelled 12,500kms in 6 years so I'm guessing that a few "gremlins" are coming out from basically being mothballed most of its life.

1. On corregated/ rougher roads I'm getting a ominous clunking in the front left. Could be bushes....could be worse. Never an issue on smooth roads, no vibrations so unlikely to be driveline I think. Anyone have issues with steering racks previously as the noise also seems to happen on parking "locks".

2. Again on corregations another noise coming from the rear. Sounds like a loose or broken exhaust hanger, but given the age of the car I'm thinking the sliencers have shat themselves. On cold start I get a "tin can expanding" noise that seems consistent with a silencer expanding and contracting.

Other than these, the car had a factory minor service pre-purchase, but seems to be running really rough at idle. Gearbox seems a tad slow respond too.

I'm wondering if it just needs a reflash to begin "learning" my driving.

What's the experience of how quickly 997 go "off tune" after servicing?

Any comments would be gratefully accepted.

 

Can't diagnose a car over the internet. Would suggest the car be put up on a lift and inspected by a competent mechanic. As for the startup sound, it is normal for these cars to rmake a deep rattle sound at cold startup. If it doesn't occur when the car is already warmed up, the sound is normal.

 

lets see some dang pictures!

 

Rotes,

Talking about pictures, could we get a larger picture of your signature pic? That is a lovely collection of flags and deserves a larger display.

Thanks

My 2006 C4S does the same when cold. It is common and not unpleasant as a matter of fact: very throaty and raspy. Once the exhaust system gets in temperature, all the parts expand and the car becomes more silent. Good side of it: You can impress a "someone" when starting your engine cold.

There is a thread in the 997 forum that a user had a loose cooling hose in the front wheel well on the passenger side. That could be the issue in the front. Read this thread. Also do a title search in 997 for rattle before you take it in. I hope this helps.
