The Autel Maxi TPMS TS408. One big learning of mine was that the version of software really matters. If is too old, they don't have the Grenadier in their supported list. If is too recent, then does not allow manual programming of the sensors (example, many of the TS508s are updated and do not allow manual programming). I found someone kind enough, with the right model, to program for me. I think I've bought one that will now allow me to as well. (picture attached - you want the 'copy by manual input' as one of your device's methods. Not all have this anymore
What you need to know is the code for each of your OEM sensors (e.g. driver front is A6F8973, etc). If you know those, you can likely find a device, or mail the sensors to one of us who have one, to try and program new sensors for you. Hope this helps
