I recently had a TPMS system fault warning. Intermittent at first ,then erratic. Ultimately, LR sensor stopped sending data. Have two acquaintances that work at a local COSTCO and both drive Teslas. They were skeptical that their aftermarket sensor would work. But I did some research and decided to press ahead and have them replace my malfunctioning sensor. It works just fine and the part and installation cost was much lower than the price of just the transmitter through Tesla ($62 at COSTCO).
PS I have a 2016 90D.
