If I set the speed to 500kb/s and connect it to another arduino running canhacker, i have to set the speed to 250kb/s - also if i connect it to my car, again I have to set the ECU to 250kbs/s but the maduino to 500kb/s - also the can_receiver code never receives anything (which uses interrupts) but the can_sender does work in both directions to canhacker and my car ECU - but i have to set it to the wrong speed for it to work.

My module was bought from makerfabs tindie store.

You have this issue if you set for 16MHZ clock speed. You need to set it for 8MHZ.

while (CAN_OK != CAN.begin(CAN_500KBPS,MCP_8MHz)

Mate you can close this issue if it fixed the problem
