How do you active jokerkey using piwis3

Stefan Eisenacher - November 17, 2022

Ich bin sehr enttäuscht von eurem Adapter
Er funktioniert nicht

Ich habe diesen Adapter mit dem Chrono Knopf am Lenkrad und Adapter A und B verbaut

Es wurde bei meinem Porsche 991.1 ( Chrono und Sportlenkrad ) von einem Fachmann auf Multifunkitions Lenkrad umgestellt

Bitte um Hilfe was stimmt hier nicht?
Ist der Adapter defekt oder hab ich das falsche Lenkrad Modul gekauft ?

Adapter 95B-959-256F

Tasten sind die abgebildeten
Es geht weder eine Taste noch brennt eine Lampe nur

Bitte um Hilfe

Hi, I’ve installed your adapter STMV1-H and the MF steering wheel with heating. I also swapped the clock spring unit. I now tried to activate these functions but I don’t have the coding for it. From where may I get the code to enable these functions?

Thank you for your assistance on this.

Best regards

I’m seeking guidance on what exactly to order to upgrade my steering wheel (got wheel and airbag) and I’ve been through the videos an installation / coding I should be on top off.

Car is Carrera 911 4S – 991.1

Existing wheel is: Sport, paddles, no MF and not heated.

New is: Sport, paddles, with MF, not heated

What parts should I order to make the conversion ?

Thx in advance

In step 8 it says “Input the enable code you get and save.”
Where do you get the code to input?

Max Lohman - April 22, 2018

How do you activate a 991.2 MF wheel on a non-MF equipped 997.2? I have installed your adapter and installed the wheel and airbag. You don’t have any instructions for programming the MF wheel for a 997.2.
