I have been reading about the need to replace the PDCC reservoir for Panamera (on models with the said option).
Should be done at 60k miles.
Since reservoir has a built in filter module that cannot be removed/replaced, entire tank needs replacement.

Have seen folks say its a real PITA to do. Started looking closer and found this photo of the tank itself. Somehow it does not appear to be difficult. There are 3 lines going to the tank.
Just guessing, if I was to remove driver front wheel and lining, I can get to that side. Then I could siphon out the fluid, protect the area with rags, etc, disconnect the 3 lines, and change the tank with a new one.

Anyone comment on the above, whether I am missing something?
Other folks were saying you have to remove the (serpentine?) belt, to get the tank out. I somehow do not see the need unless you are changing the lines too (unnecessary IMO, as I think they are metal).

Thanks for input. Below is pic of a new tank, showing where the 3 lines connect to it.

I was looking at this too; do you think it can be done without removing the front wheel and lining? Seems to me a full power steering fluid replacement might be best. Do you know what fluid to purchase and where?

Yes. The reservoir is easy to replace. Drain fluid first as much as you can, pad under the reservoir with plenty of towels, loosen hoses and screws holding it to chassis, Swap out and fill with new CH202 fluid. Done.
All from inside engine bay. On my to do list in next 10k miles or so.

Yes. Unscrew bolt holding it, pad under hoses with plenty of towels, drain as much fluid as you can (turkey baster or pump, your choice). Loosen hoses and remove, put new tank in, put all hoses/bolts in place, then fill with new CHF 202 fluid. Done.
All work inside engine bay, no need to remove wheels/linings (that is if you are doing pump work). Since filter is built into reservoir, if you replace it, you put in new filter essentially.
New tank cost about 140 from my checks. On my to do list in next 10k or so.

CH2O2? What kind of fluid is that? Certainly its not formic acid!
Ah, must be CH 202?

I believe it Is Pentosin CHF 202.

ciaka

Yes it is, gave my best to scrape my brain at night. pentosin CHF 202 (white bottle) or compatible pentosin CHF 11s (green bottle). Both can be mixed together.
Heard Porsche briefly switched from 202 to 11s due to supply chain issues, but as soon as that resolved, the went back.
