According to my Lectron contact Only U25 has SC access and F56 doesn’t, possibly i3 doesn’t as well. Our cars use a slightly different handshake method. They aren’t sure if the issue will be resolved
Yes, and my intent with that comment was to highlight that the difference in compatibility between the U25 and F56 for these two different systems seems to support the "different handshake method" comment from your Lectron contact.
