New installation Today. DS7 stalk (wiper - indicator - Cruise). DS7 performance Leather Steering Wheel, and DS7 Leather Airbag.
Installation is straight fwd but you need to make an adapter (i did) or to repin the Plug. Need also pay attension with the stalk center position (otherwise an esr/esp error wil apear).
Software Modifications have been accomplished using Vluds Psa-Arduino-NAC/RCC to let the Car understand the steering Wheel.
The new steering wheel is smaller but thicker in the grip.
For those who replacing the rt6 to nac with Scirroco this modification is a "must" because is adding more advance controls and is more suitable to the new modern cars.
Could you send config for cirocco? I did this same in my ds5 but without the steering wheel, I don’t know what to change in vlud arduino tool, also nac config would be helpful.
You have to re-pin (or better make an adapter) on one of the Plugs (grey) on steering wheel column. On the Vluds tool you need to Change to C4 gen 20010. (as far i remember)
