Cayenne 958 4 Zone Climate Control Question
Does the 4 Zone Climate Control option for the Cayenne add an additional compressor for the rear seats, or just additional AC controls and Vents?

Considering you have to replace some interior trim (B-pillars), add electronics, and since you say there is a second compressor (and all that entails), I'd have to guess not. Still an interesting idea and I'm sure my dogs and son (at least when he is old enough to voice such opinions) would appreciate it.

The 4-zone climate control has a seperarate evaporator/heater unit in the rear cargo compartment run by the common engine compressor. A diagram of this unit along with an illustration of the ductwork involved is below. The evaporator/heater unit alone is $915.00 at Sonnen Porsche. I have it and it is worth the option cost if you find or order a vehicle with it. I don't think I would want to retrofit however. Looks labor intensive.

Ugh. Just makes me even more pissed at them for not offering in the CD here.
I'm sure in a little over a month when I have it all will be forgiven, but I'm really starting to regret not just going with the X5d and saving a good chunk of cash and waiting...

Thanks for all who replied, especially wwilliams88 for the very detailed info regarding what is required to install the additional unit.
My question however is why can't this bw installed in the Diesel. I know the AdBlue tank is installed in the spare tire well so is there something else that is unique to the Diesel that is installed in the same area as the rear AC unit?

No idea why they don't give it to us here. If you look at the Aussie site (for example) it is an available option there.
Since Porsche is so exacting the best guess I have is that they don't believe Americans ever have more than the driver in a SUV so there is no need for cooling/heating in the back

Reasons unknown. It is available in the overseas markets as an option on the Diesel, but not in the US. ... So, no good answer that I could find at this point.

Porsche has offered a Cayenne Diesel in Europe for a few years, but that model doesn't include the U.S. version's selective catalytic reduction system, which meets this country's stringent diesel-emissions standards. The system includes a tank under the cargo floor for AdBlue fluid that's injected into the exhaust stream to help neutralize nitrogen oxides.
Perhaps somebody outside of America can comment if their Cayenne comes with a DEF or AdBlue system.

I am not certain, but I believe the AdBlue/DEF system (which may compete with space for the 4-way AC) is only in select markets where required for passing emission controls. I.e. I am seeing many such descriptions:

The collapsible spare does fit around it, I looked at it before ordering my CD.
I also noticed that the rear air vents had much greater flow through them when the climate
control was set to the dash vents only as opposed to automatic mode which greatly decreased
the flow to the rear. This makes sense as the air is being routed through the defrost/dash/foot
vents when in automatic mode.
