In this video I’m gonna walk you through the process that I use for hacking a VW cluster CAN bus(PQ35 platform). The tools that I’m going to be using today are very accessible price wise and open source on top of that. As hardware I’m going to be using the Cantact usb to can bus adapter, this is going to allow a computer and operating system to access and communicate on the CAN BUS. As software I’m going to be using Savvycan which is once again an open source GUI tool for hacking and reverse engineering CAN BUS data.
A few years ago i repaired my own renault dashboard and got deeper and deeper into this subject. Do to constructive reasons and also the usage of lead free solder the Scenic 2 dashboards are prone to fail at least once during their lifetime (https://www.digital-kaos.co.uk/forums/showthread.php/59335-repair-dashboard-scenic-2).
For repairs, you need a device with which you can power up and test the dashboard (without having to install it in the car).
After a lot of reverse engineering and research I was able to build an arduino+MCP2515 based can bus emulator which I put on GitHub (https://github.com/dirksan28/Scenic2DashCanEmu).
There are also commercial boards (mainly from China) – unfortunately expensive and not always available when you need it.
If you are interested, I would be happy for contribution. The project could also be used as a basis to support other dashboard types.
Feel free 😉

Thanks for the link! As soon as I find some time to allocate to this project I will take a look and see what I can use in my project.
