Hi new here a bought Carista OBD2 reader but it couldn't read my ECU for my DPF, please see the reply.
Thanks for the report, and I am sorry to hear about the trouble. It appears that the Engine ECU (where the DPF regeneration service tool is coded) in your Golf uses the old generation communication protocol (CAN).
Can anyone recommend a suitable OBD2 that can read (CAN)
Thanks
