I am looking to add a parking heater to my cayenne hybrid, Porsche say they don't suply a kit and webasto also doesn't supply a kit.

Anyone know of the part numbers needed or another firm doing a parking heater?

I looked into retrofitting this, but it's a big job. It would have cost too much money for the benefit. You need fuel lines, different fuel pressure regulator, the control module, a different HVAC head unit, create the wiring harness, all the various clips and mounts, and and of course buying the webasto unit. I'm sure there are a number of other smaller parts that I'm not thinking of. Nobody makes a kit.

I ballparked about 5-7K total in parts and labor, but I'm sure it would end up being a lot more.

 

Newer hybrid or older one?

You could do this for the E-Hybrid..

unfortunately older one! I ve heard that it is very easy for the new one

@wrinkledpants: as for the part list, would you mind sharing it with me? I d like to see whether I can find some parts used

 

In case someone wants to know how it looks like and what parts are installed. Just got a 957 TT pig in w/ parking heater option.

It should be pretty easy by the looks of it, just need a couple of Ts and a 3 way valve to retrofit. Make it a standalone system w/ timer or remote and voila.

 

As for me, I'd just do an engine preheat. This way you'd start with a warm engine that blows hot air from HVAC right after start. I'd ditch the HVAC system control or maybe just hardwire it to turn on "stupidly" for a preset period of time as the water will be circulated and heated up anyways.
It's still a 2k in parts investment but better than 7k

 

We went last winter up to Coldfoot, AK with our Cayenne diesel. Only thing we added was a 110v heat pad for the oil pan, never got to use it. Overnight at one place where temps got down to -36F, cold-soaked our diesel started right up with no more clatter then usual. It was so cold a newer Cummings Dodge serpentine belt broke upon start-up.
We looked into a Webasto heater which we could have gotten. Issue is to get our North American ECU to recognize the heater to turn it on.

 

Sounds like an expensive retrofit.
For my cars and trucks in the cold.
Good battery, maybe a heated battery blanket.
Block heater, and the right oil.
My old ford explorer would fire right up with 0-15 weight oil in the winter at -4o.
RS-A Up to Coldfoot? That is north...
