Why you or your mechanic need a PIWIS?

A PIWIS is the factory developed diagnostic and repair tool. It stands for Porsche Integrated Workshop Information System. Porsche dealer technicians use this tool to perform a multitude of diagnostic and repair functions on your car.

There are Porsche PIWIS III, the original which I believe can handle cars up to the 2014 model year, the PIWIS II which handles cars up to and including the 2017 model year and the current PIWIS III which handles all cars including the 2020 model year.

Naturally if your car is under warranty, then you don’t need this tool.

Now why do you or your mechanic need one? Well here’s what you can do without one:

1.Change spark plugs and ignition coils. (The engine module is self calibrating and will learn new parts automatically)
2.Change front rotors and pads
3.Change switches,
4.Change washers, wipers window motors, door locks
5.Change most engine sensors
6.Change your own oil (but you won’t be able to reset the service interval)
7.Change differential oil
8.Change battery (But you won’t be able to tell the car you changed it)
9.Change bulbs

Here are some basic things that you can do that require a PIWIS
1.Change the rear rotors
2.Change any suspension parts
3.Change seat motors
4.Change any control modules (There are 27 of them) All need to be coded with the VIN of the car
5.Change the battery and record the change with the gateway module
Reset the service interval

Change the PDK oil (you can actually do the PDK fluid change without the PIWIIS , well a simple fluid change, you might need it if you replace the PDK filter. the reason you might want a PIWIS for the fluid change is to monitor oil temperature. The V8 needs the oil to be a certain temperature for all the oil in the cooler to drain. The v6 wants a certain temperature to be hit behold you check the level in the top up procedure. In both cases you could likely run the car for ten miles to achieve the temperature).

Change headlight components that aren’t bulbs
Change clock spring ( will require codes which only the dealer can get but you can buy from the Chinese)

Most importantly, as many of you have discovered, it is nearly impossible to diagnose repair issues without one. The Durametric device just doesn’t come close to providing the information you need and many of the error code labels it provides are simply wrong and will lead you changing parts that don’t need changing. At $769 which is less than 3 hours labor, you can see everything a dealer can see about your car. I have a 2 and I’m going to a 3. If anyone is interested, I can try to post a video of the PIWIS II. It has a simulation mode for training purposes which is helpful. There are 4 programs in the PIWIS, the diagnostic, which is the main program for service, a wiring diagram program, a fault finding program which I haven’t found to be useful running offline and the multimeter function.
If you can share one with a buddy or some Porsche meetup groups that would be ideal. My recommendation, don’t let anyone do repairs on your car that doesn’t have one.
