Using an OBDLinkMX+, xml file has extended ID canbus message details, I can select signals from extended id messages in Input and Values, however their value remains 0. Can see extended ID messages are on the bus via external PCAN device. In Connections menu the xml file is selected with the “extended” option and protocol is ISO-15765-4.

However in the Can Monitor, none of the Extended ID messages are appearing.

I don’t think we have ever tested the OBD2 CAN connection type with extended ID:s. I will run some tests.

No, we have not got that far yet. It could be that investigating this will not make it into next release, sorry ☹

Well, I took a quick look and I think I found the issue of receiving extended CAN IDs from OBDLink CAN adapter. Fix will be in next release.
