Good luck with whatever you do with this. I really believe this is nothing more than a way to force people into a dealership to have work done. Ohh by the way you need X, y, and Z done too. I asked a Nissan dealership service person for an estimate to have my spark plugs replaced. Well this world champion service lady asked me about having my valve cover gaskets replaced while having my spark plugs replaced. I told her no I didn't need that done. She got a bit of an attitude asking me, "are you sure"? I stayed polite but I wanted to inform this champion that unlike say 2/3 of the people who come in here I actually know what a valve cover is. And that it was totally unnecessary to perform. It would've been an extra $200 for them to pocket.
Again, I hope you can get it all straightened out in a good way for yourself in the most cost effective way possible.
I ignore mine. I'll be darned if I am going to pay $100-150 for sensors for my tires. Not happening. I have a great digital tire pressure gauge that works just fine. I inspect my tires quite often anyhow. I have driven probably a half million miles without a TPMS. So, I lived without it that long. I can do so without it going forward.
