BTW, if you're in Ontario, Canada, and have a canadian BMW X5, you don't need TPMS, since the canadian system's like in Europe, where they use ABS sensors as TPMS replacement.

Since ABS sensor "counts" the wheel rotation when braking, the same system's used when driving.
A wheel completing a rotation more rapidly than the other's deemed as deflated.

Thanks for the info! My Canadian E46 M3 uses a hub mounted TPMS system, but (un)fortunately, I have a US spec 2011 X5 (build date Aug 2010).

I'm in the US a lot for my MBA program, so I'll get much more out of the free maintenance program vs the Canadian version.

It looks like I'll either need to look outside of Canada or just buy some TPMS sensors myself down the road. It's just shipping on bulky items is just painful.
