Some cars do not require sensors for the TPMS. I have a 2016 bmw 328 and it uses the ABS system to detect tire pressure loss, no sensors required. You might want to check which type of TPMS your car has.

If you get them from Amazon/ebay, then if there is any issue, you will have to contact the online seller and have them in exchange and wait for the new ones and have the shop remove and reinstall them.

After each seasonal swap, you can reset them on your idrive. No need for the dealer to do anything extra for you.
Sounds like getting them from the shop works better for me. Thanks!

Hmm, not sure, I'm still figuring out the car, the manual is overwhelming. It's a 2018. Thanks!

If it's a newer X3 then you will require the sensors. Other current models like the X1 for instance do not.

My gosh, do you know how many posts I would create? LOL!!!!! I'm giving up on that manual, giving me a headache. I just need to know the basics, safety, etc. Will figure out the rest ...

As long the car moves and the radio is on, that's all you need.

BMW normally uses wheel based tpms in the USA and ABS based tpms in Canada. If your valve stems are rubber then it uses ABS based sensors. If your valve stems are metal(like image below), then your X3 has the sensors in each wheel.

Since your X3 is newer and still on runflats then it is likely that the tpms valve steam are still the original OEM units so that should be a way to tell what you currently have.

Yes, we still have the RFT. Thanks for the pictures. Both valve stems look the same to me, except the color?

The pictures above are both metal valve stems with tpms in the wheel. Those are the OEM brands BMW uses (VDO and Huff) so you can see they are shaped slightly different.

The ABS based tpms uses normal universal rubber valve stems. No one takes pictures of them because they are normal looking but this is the best pic I can find online. The cap on yours will probably be different though.

Just wondering, for my winter tire set up, do I need TPMS, or can I leave them out? I think I'll continue to get messages on my idrive ... I read that the sensors would be helpful in detecting a leak vs. visual inspection.

You don’t need if you accept seeing the tpms error message every time you drive the vehicle .

You just bought a $50K vehicle, spend the $150 and get the TPMS......would be so annoying to have the error message for six months of every year, wouldn't it?

Thanks for pointing that out.

Actually, it's pre-owned. I've never owned or driven a car with iDrive, so that's why I asked. I wasn't sure if the message shows up on the dash or just the "message" part of iDrive, the dealer isn't helpful, so that's why I posted the question here. The tire shop is quoting $260. I'd rather not buy from ebay,
