Two questions, since I have an 02 C4S that had a mysterious noise that finally was fixed: are you sure the noise is coming from the front; what type of noise is it (sounds like . . .)? Over the months that I tracked down my noise I picked practically every part of the car as the source of the noise and the cause ended up not being where I thought it was - it was a bad weld between body panels at the rear of the car. Hope this helps some.

it really sounds like its coming from there,the noise is hard to discribe,its like a rattle but not a steel to steel rattle,i did think that it may be somewhere else so i am going to check the whole car out,how did you find the weld?

Albert,

I have an '02 C4S and have had a front end noise issue that I tracked down to my car having the shorter sport springs which when the car is raised on jacking points the springs can mis-seat on the spring mounting surfaces resulting in a strange grinding noise when turning the front wheels in any direction. In my case, this was rather easy to find, so your noise issue sounds much more subtle, but I offer it as possibility anyway.

Good Luck!! demosan cheers.gif

Mine was a rattle - like pieces of metal hitting. It was speed-specific and always happened over rough roads. I found it only by process of elimination. Was pretty sure at first that it had to do with the seat belt fastenings, so started there. It took months, and finally a mechanic using Porsche's noise finding tools tracked it down to the back of the car. Everything came out of the back interior, and he found the spot where there was a bad weld. Easily fixed and never been a problem again. So, for me, it was worth paying for a Porsche tech to snoop around - I spend tens of hours and never even got close. Hope this helps.
