How to generate CAN wakeup signal

Hello there, I have a very wierd question

I have a test bench for PQ platform which you can see on the picture: https://imgur.com/fyGPqXu

On my Bench is RNS510 and 3C0 907 530 L gateway module

I would like to simulate ignition message I use MCP2515 module with my Arduino (seerduino the only difference is that u can also put it on 3.3V operation instead of 5V)

I decided to use Instroment cluster (because I knew my RNS510 uses MFD display to send radio station information to instrument cluster so it has to have connection to this blue cable) blue cable to hook inside my CAN Netowrk

I also discovered that VW PQ cars have 3 canbuses: https://imgur.com/a/FAXZZzY Infotaiment - 100kbps Conveniences - 100kbps Drive train - 500kbps

I tried to receive some packets and discovered that packets were only uvailable on 500kbps drive train bus, 100kbps bus didn't have any data, but I guess ignition message should be on drive train bus anyway, and gateway would take care of forwarding it to RNS510 at the right speed

Since I sadly have no acsess to any PQ vehicle anymore so I don't have any real data

I did fine tune your PQ45 example, to maybe at least try to send speed to my RNS: PQKlemme15GeneratorAttempt.zip

but nothing happens, if you look at this picture: https://imgur.com/PAH2PBI RNS510 clearly doesn't see the speed packet

I know here many things can go wrong, my packet is maybe not correct, maybe I am using the wrong port to feed my CAN message to I also have acsess to radar port on my lovly harness, but since its CAN this shouldn't matter, the way I understand this is that as long as the messages reach the gateway, then it should forward them to the right module

So I am just wondering if you maybe have some CAN data from PQ platform cars somewhere or would know if it matters to what point in the CAN network you feed your data to

Thanks for Anwsering and Best Regards
