Upgrade TPMS?
I loved the Tire Pressure Monitor System (TPMS) in my 2008 BMW X3 3.0si when I first got it. It took the guesswork out of determining if I had a flat or low pressure in my tires. To be more correct it took some of the guesswork out of figuring out if you have a flat but it does not tell me which tire is flat. This means I still have to go around to all four tires and manually check each tire manually. Newer models not only tell you which tire is low, but they even give you the pressure in each tire.
I have heard that some aftermarket TPMS do communicate with factory systems. I was wondering of I could install an aftermarket TPMS that would work with the BMW factory system (so I do not have to look at a yellow warning on my dash) in addition to having a separate display that would give me more detailed information including which tire is low & what the actual pressure is. One that would display the info on my smartphone so I would not have to install a separate display would be ideal. Last edited by deathwish; 10-22-2015 at 12:00 PM.. Reason: typo |

I am not sure about the smartphone info but I have aftermarket tpms on both my x3 winter set up and my GT summer set up. Both work flawless and were much cheaper than the stock ones. They can be purchased by lots of vendors and my last set I got from ebay with no issues.

My understanding of the factory system is that it counts the tire revolutions to figure out of the tire is low, unlike an actual tpms sensor

there are two styles - the older rubber valve stems count rotations. the newer ( 2006 - on) have the actual TPMS in the tire and a metal valve stem
