I'm still waiting, stopped down to the dealership yesterday (Friday 3/18) and the car was getting close to being back on the road. I'll be sure to post and update and hopefully have some more information.

 

Bad news, picked the car up today and it's still making the exact same sound. Frustrated...

For those following the thread, the engine mounts did not solve the issue and I don' know what my next step is just yet.

 

Many people have speculated its resonance due to some
slight lugging. Perhaps that’s what we’re dealing with here. Mine doesn’t do it unless I’m really light in the gas.

 

Mine seems a bit more rattle oriented. I'm familiar with the lugging at very low RPM, this seems to be something beyond that lugging phase of the RPM... I usually feel the lugging around 1100RPM in 6th or 7th gear (PDK)

Here is a video with audio


I also took audio using a Zoom H2 microphone if anyone is interested.

 

that’s a shame. Maybe it’s just normal for this car. I need to drive another 992 to check.

 

Ive had mine stored for awhile, so I need to go replicate the noise again to see if it’s like yours. I don’t recall it being that pronounced however.

 

It's hard to tell if it's really an issue or what we all here w/I listening to it in real. Mine has resonance noise around 1800 in eco mode when slow accelerating, almost lugging. Drove it with various tech and they all told me normal for these flat 6. So, I got used to it or simply avoid that rpm and going slow.

 

I'm having trouble picking up the noise. Maybe my range is not sensitive to it from all the headphone wearing in the service...following though

 

This may not be the same as mine but what my dealer found was that the struts and shocks were not properly tightened. When I went over bumps in that RPM the sound was very prominent. They replaced my rear shock and assembly and the car drove fine since then.

 

Thanks for this, I'll bring it up with the dealer. Curious why they replaced the shocks and struts as opposed to just tightening? My noise seems to be coming from the passenger rear fwiw.

I went this weekend and drove a 992 Cab at the dealer, it made similar noises as my car, but not as prominent. For now I've decided to defer the issue, if I keep the car in sport it is much less noticeable.

 

chris. Sorry to hear the news. You still here the clunking (some have called lugging) coming from the rear of the car?

did the dealer make any further comment on the noise that is still present?

Mine also has some annoying vibration in Normal mode at lower RPMs. Sport mode fixes it. Build date was Feb 2023.

 

The intermittent clunking goes away at around 1800 RPM. Sport mode brings the RPM up above that . The design of PADM (Porsche Active Drivetrain Mounts) seems to be the problem as per several Porsche Technicians. So far no fix for this problem has been offered by Porsche!! Some of the owners on this chat have had the both PADMs replaced with no improvement!!

When will Porsche acknowledge the problem and have a recall to fix it.

Let’s keep asking that question until they do. It’s not normal to hear that low RPM clunking on a such a sophisticated automobile…

The plot thickens for my personal situation, car was scratched (rear bumper) during the extended service visit to have the mounts replaced. It ended up being there for 38 days.

Now I have a scratch on the rear bumper cover that requires a bumper repaint. At this point I have requested the car be purchased back and start over.

 

Unbelievable turn of events. Let’s see how your dealership deals with the situation.Good luck. Keep us up-to-date.
