Hi all, I've been lurking for a few weeks doing research, so thanks for all great info. I finally found my new (to me) 2019 Cayenne Turbo, but I'm missing some hardware for the engine splash guard.

Any suggestions for what's supposed to be here or what I should order?

 

Order, but finding a part number for fiddly screws can be a challenge, from experience.

I would show the photo to a dealer parts guy and ask him for a bag of belly pan screws. If he doesn’t know what to do tell him to bring the 16 year old lube tech over for advice. The belly pan needs removed to change the oil.

 

The panel attaches with an Oval Head Panel Screw, Porsche / Volkswagen / Audi Part # N91057001. Same as that circled in your picture and labeled #27 on the parts diagram.

The panel screw attaches to a Clamping Nut, Porsche / Volkswagen / Audi Part # N91242501. Same as that squared in your picture and labeled #24 on the parts diagram.

From this parts diagram:

It looks like you’re missing three screws; the clamping nuts look intact. I’ll bet your local hardware store will have similar screws that will work just fine. I believe the screw has a Torx T5 head. I’d splurge for a stainless steel version to prevent corrosion.

 

Thanks! This is exactly what I needed and much appreciated.
