My car feels new all over again today. And it's possible this might help someone down the road:

My new GTS developed a rattle at about 1500 miles, somewhere behind the driver's side dash. It was much more pronounced when the air was warmer - above 40 or 45 degrees, which made it intermittent throughout the winter. But when it was happening, it was a serious rattle that went well beyond the normal noises we all know these cars make. It sounded like something was loose deep inside the car - not a plastic resonance like most of the noises our cars make, but a metallic noise.

The first time I made an appointment, or course the temperature dipped into the 20's. To my dealer's credit, they took it seriously, and investigated. He found a bulletin about a fuel tank bolt that could rub on the firewall, and replaced it with a different bolt. Someone here had that done as well, so I was hopeful, but halfway home, the rattle was back.

Appointment 2: A tech hear the rattle clearly, and spent an entire day investigating. He said he put felt all over the interior and took care of little noises he was hearing in the doors, dash, and cowl, listening with those headphones they have. But after 8 hours, he was completely stymied. He asked me to make another appointment when another one of his colleagues would be back from vacation. And apparently Porsche has a roving set of engineers that they send around for problems the dealers can't handle - he was planning to call that person in if he couldn't fix it.

Appointment 3: I dropped the car off 4 days ago, picked up a Cayenne loaner, and told them not to give it back to me until it was resolved. The noise had gotten to the point where passengers would say "what the hell is that?" Since I'm a fanatic about this car, I nicely told them I wanted it stored inside at night, and I didn't want it sitting around in the rain.

FINALLY: I got the call today that it was done. There's another bulletin about the fuel tank - the foam pads that it sits on against the frame can come loose, or perhaps they were installed incorrectly, and that causes rubbing. Porsche has a new version of the pads. It requires draining the coolant, dropping the suspension, and dropping the tank. Took them 9 hours of labor. And after an hour of driving, it seems completely gone - thank god! After watching that 993 Turbo burn up at the NY Auto show, I was getting ideas about my car.

So if you have issues, stay with it. My first instinct is to not trust dealer service departments. And I hate having my new, carefully cared-for car sitting around a dealership. For the first appointment, it sat out for a day in the rain, which really pissed me off! But when I spoke up, they took it seriously, and they really worked hard to resolve the issue. I'm satisfied. It feels like a brand new car again - it's amazing how much this detracted from my overall experience when it was rattling.

After reading your post, I felt bold enough to give it a try. Thankfully, the head tech jumped in my car and within 20 feet of driving he heard the sound. I mentioned Rennlist and the "foam pad" solution, and he took the car in right away. I picked up the car today, and PROBLEM SOLVED!!

In my case, they mentioned the repair solution as "ATI #1403". They removed and re-installed the fuel tank, cover rear removed and re-installed, and coolant drained and filled. Looks like the parts replaced were 2 "Foam Part" (991-572-529-00) and coolant.

I'm not sure if this is only in my head, but it feels like shifting gears (shift lever) has also become significantly easier. Strange, but it feels very different (in a good way).

Anyhow, thank you to the OP and everyone else who contributed. If you're suffering with noise, I'd suggest you take your car to the dealership.

It's not always, but definitely more prevalent when acelerating/slowing down around 15-20 mph. something moving. I highly suspect the tank pads too... I'm booked for next week, I'll see if Porsche will help with that post warranty of if I have to eat it...

The sounds went away 100% when I got down to half a tank, but I don't want to own a car that I have to keep low on fuel all the time haha.
