I'm a fairly experienced DIY detailer, but this is my first go around with a full leather interior in my 2024 Panamera. The dashboard was recently replaced under CPO with only 6,500 miles. Upon purchase, I noticed it was warped with a few leather bubbles. The car was sitting in a hot outdoor dealer's lot for a while. I now have it parked under cover, day and night, and use a sunshade whenever parked outside.

I have my own routine for the rest of the leather, including a monthly wipe with a damp, soft microfiber soaked in highly diluted interior cleaner (3D LVP or DIY Rinseless) and the occasional protectant from a few ultra-premium brands. I realize the leather is coated, but I still like the protectant on certain areas, especially on this car, which has had more exposure than normal for its age.

Now that I have a fresh, matte dash, I am hesitant to use anything aside from a quick wipe with the mostly water solution. I also recently bought a bottle of Leatherique Pristine Clean, which supposedly has light-cleaning and light-protectant qualities. I am considering using that.

For those who have had full leather interiors for some time, what have you had good success with, especially on the dashboard?

I have a 2024 Panamera V6 RWD that I bought CPO with 6,500 miles, now at 10K miles. I'm trying to diagnose an issue that appears only in Sport Plus, when the vehicle is warmed up.

I've noticed a steady metallic noise when in manual mode and accelerating, only in low rpms in 5th gear. I don't hear it in any other gear. The noise is only present when the car is warmed up and in Sport Plus, in any suspension mode or ride height, but only Sport Plus. It almost sounds like an exhaust rattling and making contact with the frame or heat shield.

The it was difficult to pick up on my phone but you can somewhat hear it in the following video:

My main question is, what else is different in Sport Plus that is causing this noise? If I switch to Sport or Normal and recreate the scenario, there is no noise.

Since suspension mode or height does not factor in, are there active engine mounts or other components that are enabled in Sport Plus? Perhaps exhaust flaps?

The dealer looked at it and claimed they solved it by cleaning out debris, but I immediately heard it upon pickup. Thanks!
