Cayenne: How to fix leaking sunroof drain junctions?
Hello, I have been having water leaking problems in my 957 beast and after reading many forums on here, I was able to fix many previously thought potential causes, but water was still coming in!
Here is what I have done:
1- I removed the front wheel liners and cleaned the area between those plastic covers and the firewall.
2- I plugged all rubber seals from the inside and the outside.
3- I cleared the AC drain and made sure it is installed properly.
4- I removed the roof racks, all the way down to the tracks which have rubber seals underneath and around the 5 screws on each side, I sealed those with silicone and reinstalled the tracks only.
Every time I did one thing, the problem seemed to disappear, but not for too long. Finally, I found something on youtube about pouring hot water and soap into the four drain holes located on each corner of the sunroof. I did this on one hole at a time, and while water dripped from the bottom of the car to the respective side of the hole I was pouring water into, here is what happened from the inside:
1- The A pillar on the driver side leaked water into the footwell, and it was soaking from the emergency brake downwards.
2- The footwell of the passenger side felt a bit wet.
3- Pillars C and D on both sides leaked aloootttt of water, around the handles, into the headliner and all the way down the pillars.
Now I know it must be the junctions of the drain tubes coming from the sunroof. Question is, can I reach those by just removing the pillar covers? Or do I have to remove the entire headliner?
If so, is there a DIY to remove the headliner and fix those junctions myself?
Any help appreciated
I attached couple photos of the water damaged areas

I'm experiencing a water leakage problem with my 2018 Panamera as well. The filter was completely wet when I pulled it out, but I'm still unable to determine the source of the water. I'm unsure whether it's due to rain or the AC.
