Does your car have a separate TPMS unit?
What protocol is available for diagnosing your TPMS unit, VWTP 2,0 or UDS protocol?
Its UDS protocoll.

in the screenshot the VWTP2.0 protocol is more likely based on the ABS block
Its from the abs block, your right.
But how can i send back to the canbus?
Can u help me with correct syntax?

did you take this data on the CAN bus of the diagnostic connector or on the internal CAN bus of the car?
You didn’t write your ultimate goal, do you want to get tire pressure data in TORQUE?
its from VCDS, Its a gateway on the car so i have to cut the wires. i dont want that.
i want tire pressure info thats right, i want to use it on the arduino.

you must analyze the responses from the ELM327 programmatically in Arduino and, if you need, write the responses to the log
