Got word from my dealer that yes, the TPMS can be installed but a cost of $1200 ($800 parts and $400 labor). But she suggested I wait since the BMW rep told her that BMW might be doing something about this. The dealership did not even know that all of their 2021s came without the TPMS until I asked about it. So I am guessing that there is some pressure on BMW to provide some type of fix with this from the dealerships. I believe adding this as an option was about a $500 additional option, so if they do something like this, I would be fine. She also said the current price includes a discount for no radio or TPMS, I do take that with a gain of salt but hey, buying a BMW is not for the weak of heart (with regards to money). Still have not heard anything from my email to BMW customer service. So potential buyers, write them to help increase the pressure for a fix.
