Carpokes Porsche Forum

Wife got a Metallic Umber (silvery brown) Cayenne over the weekend. Sweet Power Cruiser. Runs super, looks awesome, very fast (its an "S"!)
It tuned over 100k miles on the way home from buying it. Looking over the service records, it looks like it was Dealer Serviced, so nothing really done except changing the engine oil. I'd like to catch up on the maintenance, as from the records, NONE of this has ever been done (might have been done but not recorded):
Air filters
Cabin Air filter
spark plugs
trans fluid change
diffs fluid change
transfer case fluid change
drive belt
Power steering fluid change
brake fluid flush
Also Needs:
Needs a another Key fob (only came with 1)
Weathertech floor mats (we live on a dirt road in the mountains)

What Am I Missing? Its in great shape and has been in Phoenix and Abq all its life. Is there something like the Coolant hoses in previous Cayennes that needs to be changed?

Plastic coolant pipes under the intake manifold , they are prone to crack/leaking due to heat cycles . The fix is to replace with aluminum pipes . You might want to consider the starter as it sits in the valley under the intake .

Is this a thing on the 958 (gen2) Cayenne. Definitely on Gen1, but I thought they fixed this on the Gen2s

Hiya. New to the forum and my first post. I have a 2013 Cayenne S and I think it may even be the same color. Last year mine developed a coolant leak beneath the intake manifold, and though I didn't get specifics at the time from the shop, but as I understand it Porsche was still using some plastic hoses in the V of the engine for the 958 models.
