Replacement of steering wheel on Passat B6 2009 with 12-button steering wheel B7

My Passat Variant B6 is equipped with a multifunction steering wheel (see photo: Steering wheel Passat B6 2009.jpeg), which likely uses the DDP protocol. To use the user profile dialogue from the UH-V Premium, I need a steering wheel that uses the BAP protocol (see /viewtopic.php?t=30593).
A multifunction steering wheel from the Passat B7 with 12 buttons should be compatible with my Passat B6 variant. I hope that, despite the two buttons on the back, the 12-button steering wheel is still present (I mean functionally, see Photo: Lenkrad Passat B7.jpg).
The connector for the steering wheel buttons on the B7 steering wheel is not compatible with the socket on the airbag module (see image: Stecker Lenkrad B7.jpg).
Stecker and connector for the steering wheel buttons are 5-pole, and 4 poles are occupied.
The locking mechanism on the airbag module connector can be reversibly removed (see photo: Airbag module connector.jpg). After that, there is a way to reconnect it, where the free pins are mirrored opposite each other. Only 3 poles are connected. [/url]

Also, does the airbag module also need to be replaced, and will the connector on the steering column still fit?
Wouldn't it be enough to simply re-label the cables of the connector on the steering wheel of the B7?
Can anyone provide me with the connector pinouts for the steering wheel airbag module (Passat B6 2009) and the steering wheel of the Passat B7?

Moin,
mit Deinem Ansatz kommst Du nicht weiter.
Das Multifunktionslenkrad muß mit dem entsprechenden STG kompatibel sein, beide mit dem Kabelbaum und den weiter verbundenen STGs. Daß ein B6 Teilsystem mit einem B7 Teilsystem so einfach austauschbar ist, wäre verwunderlich.
Das gilt auch für das Airbagsystem. Änderungen sind hier sicherheitskritisch und nicht zulässig. Vom Hersteller wird es dazu sicher keine Freigabe geben (auch nicht für die Verwendung des Lenkrads).
Fazit: Finger weg!

Hi there,

Maybe someone can still help me.

My Problem:
- I have upgraded my FSE-Plus to an FSE-Premium (5K0 035 730 E)
The new FSE was used, had a user profile, and worked immediately with my iPhone 8. The only drawback was that the charging cradle (Cradle) had no power.
- I received information from the seller that the charging cradle could be coded according to the FSE. I wasn't able to do that, but I also reset the learning values in the FSE at the end.
- Now I can't use the input for the user profile. The FSE (BAP protocol) doesn't understand my MFL (probably DDP protocol).

My questions:
- is it possible to achieve this through a new MFL and possibly a different department?
- or can you perhaps encode the user profile?
