I use DSG dq500 in my mini r58 but there are three messages that clash with my body can stream ( _0x0C4, 0x480, and 0x580_) so that I can’t just merge them.

The streams used to be separate (body \<500\> pdm \<1m\> ecu \<500\> DSG) but I switched to another ABS module last week and now the EMU pro CAN stream simulation could be very useful (4 bit counters and checksums are a mess).

So I tried using my PDM as a gateway. Switched the vehicle stream target to can1, received with the PDM and retransmitted to the body Can.  
Worked Fine for the body/abs part but as far as I can see the **DSG stream (can2) breaks down completely this way** and no messages are sent from the ecu, only from the Gearbox.  
Switching the vehicle stream target back to can2 fixes the DSG stream. They coexist just fine and I can see no errors.  
Switching to can2 and back to can1 actually triggers the dsg can stream back to life and I can start and move the car until I switch it off.

I believe it could be fixed and meanwhile I’d have to switch both PDM CANs to 500kb to work around that or use a real gateway.

Could you have a look?

Thank you for pointing it out. I have identified the problem and we will fix it in the next beta version. We are going to release a recent 261.2.1 RC2 version as a stable version soon, however it will not contain the fix.
