Title: PQ35 CAN-Matrix of Comfort Bus
Post by: elias on November 15, 2023, 12:09:34 PM
Hello together,

I am searching for the Can Matrix of the Comfort Bus of PQ35 Vehicles.

I know that its definitely exists in the "wild" but i havent found it yet. I received a Screenshot from some who have it, but is not willing to share the whole matrix(see attachments)

Here are some resources which i found and want to share:

Try searching for dbc files, although I don't think the comfort stuff is part of any damos leak, since nobody cares about it.
Also, I am not sure at all that screenshot is from comfort can.

Yes, you right. It isn't comfort bus message on the picture.
It's for main high speed bus.
For PQ35 GRA_Neu messaqe (0x38A) is transmiting from Gateway and receiving to Motor/Gearbox.
Here is message layout.
