Hi all. I just got my Cayenne S back from dealer yesterday. Here is the recap of my original post: A strange thunk noise was heard when I made a slow 90 degree right turn. Here is the link to the original post.

Here was how I found out how to reproduce the noise again and again.

1. First drive safely, and find a safe and close road to try it.

2. A car needs to be warm up, not the engine, but the steering related parts. Therefore, a short drive is needed, we (dealer's technician and I found a 15 min. drive should be enough).

3. After warm up the parts, a test drive can be performed. Make a hard right turn. Here is how: Give yourself a enough space for your car to accelerate ( I would said about 50 MPH). Before the right turn into an alley, break hard (not racing hard breaking, but sporty hard breaking), then right turn into the alley. By doing so, the car's right front suspension should dive, the noise reproduced.

After a 3 weeks in shop back and force "debuging" the problem, I finally got an phone call from my dealer to told me the problem was fixed. The dealer had tried several things, and finally a steering rack replacement solve the problem. I am a very happy driver for now, and hope the problem will not come back. My dealer gave me an almost brand new Boxster loaner car, and I was almost want to take that Boxster home with me as a daily driver! The Boxster is really a fun car to drive, but when I drive my C-S, Wow my C-S is really fast, powerful, and the suspension is stiffer (even I set the air susp. to soft).

 

Any chance of posting the description and solution on the work order from the dealer? I can duplicate the noise in my truck by driving down my parking structure ramps and turning the wheel between 270 and 360 degrees. I had the truck into the dealer in the past but they could never duplicate the click/thunk that occurs for me.

 

Same here.

 

Mav - what dealership fixed your car? I am booking another appointment right now (my third for this complaint) and my dealer wants to verify exactly what was done. Feel free to PM me if you wish.

Thank you!!

 

Hi all, I will try to scan the work order form and post it. The dealer ship that I went to was Pacific Porsche in Torrance, CA. I can only said that they had done a very good job. It was a very time consumming process ( so I call it debuging) which requires trying, fixing, test driving and on and on. I am happy that I finally find a dealership who is willing to spend time on fixing my car's problem. My former and current service advisers are very helpful and knowledgeable. Their attitude is the best that I had ever feel around the Southern California. This is also why I would rather drive 50 miles to them not 14 miles to the closest. Of course, a Boxster loaner is another +. BTW, if anyone want the name of the service adviser, please PM me.

 

Thank you VERY much.

 

Hey Mav,
I am definitely interested in the name of your service advisor at Pacific Porsche. I'm taking my cs in for the seatbelt re-call notice and some other small little things and the last time I went to Newport Imports which is basically in my back yard but I didn't get a loaner car. Does Pacific Porsche always provide loaner cars? If they do, I too would be willing to drive the extra miles!
