After much searching of the interweb I found an Australian website telling me that I can read a QR code from a new injector to enable me to code it. Fine, except I can't read the code. I mailed a pic from my phone to pc then uploaded it to various decoding websites and they all say no QR code found. Can anyone help/advise? Are the numbers on the shaft of the injector - below the part number - any use?

TIA
