PIWIS II will not diagnose 996 and 986

Recommended Posts

I have a PIWIS II system running v17.500. It connects and diagnoses to anything later than 2005, eg 997, 987 etc, but it will not allow me to run diagnostics on 996 cars. I can select Porsche 996 under the Diagnostics menu, but when I start to interrogate the car, I get presented with a menu of cars that are all 997 or newer. I tried selecting 997, but the diagnostics fail.

I can still access 996 OBD with my Durametric pro, but I would like to be able to use PIWIS on 996 instead.


Anybody have any suggestions on how to fix that?


Also, is there a way to update maps, program keys for '09 and newer cars outside the dealer network using this?

The PIWIS 11 will diagnose the 996  and even further back to the 993, 964,, 928 and 968 if you have proper adapter plug.  I have helped with  quite a few  PIWIS II units and all of them cover all models from 90''s forward up thru 2017 models.  

Please post a photo from your screen after you have selected doagnostics an f then , 911 with the various 911 models it is displaying.  That should and confirm that you have 18.1 and the models available to you as a start.

I rebooted yet again and this time success. No changes made, no configuration different, same cable and same car. Now I can access 996 through OBD. Maybe some kind of glitch.


I noticed that my software was actually 17.5, not 18.1.

you probably have a bad Samtech interface,
It is surely an interface FTDI type ALLSCANNER, it emulates the samtech driver to work.

in the periferic manager, either you hsx for the original head or very good copy or com com for the wrong head.

If you want to have the certification open your case, you will see right away if it's a samtech or not,
double pcb - samtech
simple pcb - all vcx scanner bad interface
. use google to see the differences ;-)

sorry for the translation I am French-speaking Belgian.

See you soon
