Oh where are you located ? I have this issue too, but everyone is quoting me 1500+ to pulldown the gas tank etc.

 

I'm in San Antonio, Texas. Shop is German Car Specialists. I sent my guy a couple threads from Rennlist in advance so he could research the issue. The one I felt was most compelling for it being a simple fix was this one: https://rennlist.com/forums/991/1032...t-service.html

We had a conversation over email and he cautioned that it might be more involved than that, so yeah, he might have been thinking he about dropping the tank. We also weren't sure my Fidelity Platinum warranty would cover it. In the end I'm certain he didn't drop the tank and was able to locate dislodged foam pads either from the top or bottom with panels removed. I didn't file a claim, so can't say about the warranty.

 

Interesting, I took my car to the same dealership in the SF Bay Area that original post creator used and they never heard of this fix LOL. I guess different days, different techs. I will try to tackle it myself this weekend.

 

I feel like a TON of people will get value from this. Don't ask me how I got this can't tell you. LOL.

I just performed this on my C2S, takes about 2 hours assuming you have a lift, You def DO NOT need to drop the entire fuel tank, just wait until it's empty. and you can drop the lower cradle and maneuver any pads up there, I used some foam pads I found at home depot and for extra protection I sprayed some lithium grease up there. All is quiet My car is out of warranty.

The photos below are from underneath the car with the tank removed, but YOU DO NOT need to remove the fuel tank, if you drop the lower cradle you can pivot the gas tank just enough to shove pads up there with a long screw driver. In my 2013 I did not even have any pads up there at all. I was told by a porsche tech they use super glue to stick the pads back up. I actually used some higher density foam with adhesive backing and used the clamping of the gas tank and the chassis to hold everything in place.

 

Joe, that is amazing! My squeak has come back (albeit, quieter than before the dealer attempted to fix this) - I might have to try the same thing. Now that I can visually see where the factory pads are, it makes way more sense.

 

I also noticed this squeak last weekend after I filled up gas but the squeak is less noticeable when the the tank is at 3/4 so I don’t think I’m going to fix it as I’m out of warranty.

But I’d like to ask if there is a fire hazard or any potential danger from not fixing it? I don’t want my tank to fall off lol

 

No safety issue.

 

Good to hear koala. Thx

Does the squeaking gets worst overtime. Mine seemed to happen at low speed mostly. After a week, and a quarter tank gone , the noise is pretty much gone.

 

I suppose if those pads were just sliding down over time that it might get worse. But, if they're not even installed, which is the situation in many cases, I can't see how it would get any worse.

The squeak is definitely way more noticeable with a full tank on a hot day. Less noticeable / non-existent on cooler days or with less fuel!

 

Thank you for all the good infos 🙏

 

plastic rubbing on metal never seems like a good idea to me.

 

We should complain to the NHTSA. Over time this could be a fire risk. Fuel tanks should be secure and not striking the firewall. Maybe the NHTSA could convince Porsche to fix the issue for those of us out of warranty. Dealer told me at least 8 hours of labor plus an alignment, well over $2k. FWIW the service advisor claimed it wasn’t a fire issue (candidly I don’t trust his opinion at all). Less than 5 minutes to file a complaint with the NHTSA.

Cheers,

assuming you do not have an AWD variant. You can do this yourself in 2 hours or show the tsb to your local indie and I am sure they can do it in 2-3 hours tops.

 

My thought process on this is that the gas tank is intended to rub against the firewall, otherwise, why would they place those thin pads there? Realistically, if it wasn't intended to rub against the firewall, there would be no need for pads and the tank would have enough of a gap that it could never touch anything.

 

OK, maybe a dumb question here, but why should there be any "rubbing" at all? Shouldn't everything in there be solid and in place without any jiggling, making the pads unnecessary? It seems like the pads are a stopgap measure for an engineering flaw.
