* It seems that some DQ200 have the same Hardware number but we never tested them, please be careful as we cannot assure you that the DQ200 will work with our VAG DSG CAN protocol, DQ500 not supported as of now.

Note: It might work with other TCU numbers also, if you are having problems with a specific number, or want to report a successful DSG control, please contact us.
