I suspected as much. And it appears Mercedes/Smart would have to be involved with their proprietary computer mother ship reprogrammer if they could do it, which I doubt they would. I don't have to deal with any safety inspections so the best advice I heard is to put a piece of tape over the dash warning light if/when I delete the OEM sensors, and go on in blissful ignorance.

Not really, you still have the valve stem mounted remote TPMS system on your SMART with the display in your motorhome.

PS nice talking to you on the phone about your add-on TPMS system.
