Hello all

Can anyone let me know the factory recommendations for the fluid flush intervals?

Brake fluid: every 24000 miles

Differential fluid flush: ???

Transfer case oil: ???

Transmission fluid (I have 6speed manual): ???

Power steering fluid: ???

Assuming one wants to keep the car for at least 120Kmi, does anyone believe that the tranny and diff fluids can really last that long? Seems that all of the metal particulates are in there for too long, causing higher wear and possibly even varnish build up. In all of my previous cars (with synthetic and regular ATF), the recommended replacement interval has been 30Kmi.

Thank you!!!
Are you sure this applies to Cayenne?
It said 911 cabrio, also my manual has the spark plug interval at 36000miles for example......

They could last up to 120k miles, but I wouldn't recommend leaving it that late. I had the transmission, diffs and transfer box oils changed at around 60k miles and the transmission and rear diff oils were in really poor state - extremely dirty and they didn't smell normal.
