On the forums for my old pathfinder, the field service manual was widely circulated as a download copy (schematics as well as part numbers and service instructions for basically the entire car). I was wondering if there was anything similar to that for our cayennes?

 

It's all online in a system called PIWIS/TSI and you have to pay for it. This is the same system that the dealer Techs use.

The registration has a bunch about you having to be a tech, but anyone can sign up. You credit your account in increments of $10 or $100 and each document has a price (most are <$2, but the wiring diagrams are $$$). Unless you buy the yearly subscription ($5k last I looked) the purchase of a document is only good for that session. The registration itself is free though.

Unfortunately it demands IE and an ancient Adobe plugin (for the images) that not even Adobe supports any more. I use a Win7 VM using Oracles VirtualBox on my Mac and I downloaded a PDF "printer" driver so I can save the documents as I purchase them.

If you are in the USA, when you register you have to scroll to the bottom of the form and use the "Other Countries" link and use that form. If you use the main form there is no USA option and if you select "Other Countries" in that last then you can't credit your account.

 

Sorry, forgot the parts bit and PIWIS sucks for that. The Tech system for the parts is called PET, but I don't know of a direct access to that. The best public (free) site for parts diagrams is Auto Atlanta's site:

Thank you for the information, although it is sad information

is there a reason why these electronic documents are priced so high? are they continuously updated or any other reason such as that? I mean, I can see why the price would be high for print versions, but duplicating electronic copies should be very inexpensive to produce.

maybe I'll do some digging to see if those documents have been converted to PDF then disseminated among people who go the DIY route for our 958's even though it seems other than oil changes or tire and brake swaps, I havnt found people who say, does the full 30k/60k mile services themselves.

 

Mainly Porsche (on any MFG) doesn't want you to have the work done anywhere but at a dealer. While they can't legally require you do use the dealers, they can make it difficult/expensive to do it elsewhere.

The real kicker is that each $2 page is very specific to a task. So even the OCI actually points you through 7 or 8 pages if i remember correctly. In that example, however, you can skip most (all after the first time really) as they are things like removing the engine cover. I think the only two i originally needed were the OCI itself and the torque specs.

What I'm finding frustrating is that they "update" the docs every year, but in all the docs i've repurchased so far nothing about the procedure has changed. You don't know until you download it again though.

I'll do my 20k myself (sometime this winter) and i'll also do the 40k too when the time comes. On the diesel its mostly just checking things out visually with a few parts being changed.
