Power steering fluid

Where is Designer? Hey Designer - can you spoof the Cayenne Owner's Manual with your famous PS skills - one page only, perhaps two instructions:
(1) Drive vehicle to nearest Porsche Dealer.
(2) Hand wallet to Service Manager.
Put a little bad-German-translation English in there, for good measure.

Same index contents, BTW, but every reference is to Page 2.
I'd buy one of these special editions, btw. Maybe I'll cross-post into the PPT thread as an incentive like Don't Wait - Order Now!

202 has slightly better high temperature stability then the 11s fluid - but as was pointed out, they are compatible. Strangely the 202 fluid was cheaper at full retail from the local Porsche dealer then the CF-11S was from a NAPA auto parts store.
So - in this case - going to the dealer would save you money.
OP - you may want to find out why the fluid was low. Power steering fluid isn't "consumed" like engine oil. The level should never drop. If it drops you have a leak somewhere (very common on BMWs - their hoses suck, haven't seen it on the Cayenne..)

There is a TSB that states that 202 supercedes the 11S and that it is backwards compatible and OK to mix the two. It is TSB 4802 and dated back on 5/05 so I'm not sure when it showed up in the list for all to see.

I order the CHF-202 from AutohausAZ.com, it's now $18.74 ltr. Not worth it to order just one can but I usually order it w/ ATE brake fluid and Lubro Moly fuel treatment. The 202 is the recommended PS fluid for all the Porsches these days.

Thanks for all the replies. My car has 44k on it now and I don't think it was ever checked. The reading was below the minimum line on the reader. I was wondering whether I had a leak or not but the car never had symptoms and I park in my garage everyday and there is no fluid leaking from the bottom. I topped it off and I guess I'll just keep a close eye on it. Just by chance I checked it yesterday.

I have an overstock of 11S. Is there any reason to really avoid using it in the steering system? I know they are interchangeable so whey did they go from full synthetic to semi? I am sure both are excellent but 11S being full synt. Should be good in the system unless the full synthetic eats seals or something?

No problem using up your 11S. Both fluids are full synthetics. The CHF202 has a slightly higher viscosity, not sure if that was something Porsche wanted but the big change is the flashpoint is over 100'f higher with the CHF202.

Thanks. I used the 11S. I am not that worried. Will change it out in a year to 202 but the stuff in there was old and brown. I read somewhere the 202 was semi-synthetic and the 11S was full-synthetic. 202 is 130˚F higher in flashpoint. I won't worry about that for now. Should be fine. Messy job I will save for another day. Thanks
