you need to re pair it as it has component protection. cant be done in vag come you need official vw dealer tools

If you need any help with the CAN bus software side of it I am happy to provide assistance since I am very familiar with the CAN architecture and message on the Smart Roadster!

So I performed some can sniffing from the drive unit and uploaded all the logs onto github here:

I cant find any dbc file that matches up correctly really.

Drive unit seems to only transmit 7 can ID's if isolated.

Hey Seb.
The component protection and immo is detailed in some of the VW SSPs it just notes that the module is involved in both aspects.
A good start is to pull some of the Ross tech forum posts to see what details they have being pulled from each module.

I was hoping that the component ...

I have attempted to log the powertrain data from an id3 but unfortunately it uses CAN-FD. now just waiting on a new can to usb with FD compatibility. also from what i read the module might have component protection rendering it useless.


Where did you hear it has component protection, and if so ...

Details ...

Wow! thank you, some great information there :)

Unfortunately the iBooster came without the master cylinder. At the time it didn't seem to matter as a) I didn't plan on using and b) it was so cheap that it either doesn't work or was wrongly listed. Either way it will do for mocking up the install ...

Hi Pete,

Yeah connector kits for iBooster in stock and available here: https://sghinnovations.com/?product=bosch-ibooster-connector-set

Thanks for the kind words on my install.

You want the Tesla version as its nearly a bolt in, and the VW one will be far more awkward to fit. The Tesla one ...

Hi Pete, I have a full official CAN .dbc for the smart roadster. Lmk if you want it.

I also installed a iBooster in my roadster for using with openpilot: https://youtu.be/Te4AhlRXnLw

I can give you tips on full install of ibooster if you need to help. Bolt pattern is straight fit. However I used ...
