2015 C4 B7 TPMS

[DHallworth]

I think my version of Diagbox is too old for this car, that's the main problem.

To update the software any more I'd need a newer interface which I don't think will do the earlier XM's.

What puzzled me the most was when the Snap-on device wouldn't talk to the TPMS ECU either. That kinda lead me down the path of thinking that it was the ECU.

However, after buying the Autel to work on a different toy, I figured I might as well try it on the C4 and to my surprise it worked perfectly.
