Mein Auto: 745i 528i
Changed from 18" to 20" - tpms malfunction

Went from stock 18" OEM wheels on my 2010 750i - to 20" 303m OEM wheels.

I bought complete set up - wheels, tires and tpms. Though I don't 100% know what car they came off or if there is actually tpms installed (seller says yes)

I go into menu and reinitialize the tpms and after driving a bit I get a tpms malfunction message.

Any ideas?

They may not be the correct TPMS for your car. I am no guru on TPMS but I think it needs to be the proper match for the vehicle. Some one else will need to chime in here.

Or, the batteries could be bad, I had a set of wheels last year where three of the TPMS stopped working at different times because of a bad batch of batteries.

Your tpms sensors will need to be programmed to your car. To put it simply, they most likely work but your car doesn't know their address so it can't speak to them.

Is that true? Never seen that before. As long as the sensors have the right frequency, shouldn't that just register within some miles of driving/reset?

I have had sensors with a bad battery which needed replacement, or the wheels could have been sold without sensors.

Are the valve stems metal or rubber? If rubber, there are no TPMS installed...

Tpms

They are metal stems and look like tpms - only brought it up because I was not 100% sure.

They will be need to be programmed. it is the same situation if you were to replace one of the sensors on your current wheel setup. The "address" of that new tpms sensor would need to be programmed to the car so that it can speak to the car.

Is this a DIY thing or only dealer?

If you have the correct TPMS, you just have to initialize it and drive for awhile. The car will auto detect.
but if "one" of them are not working properly, the tpms malfunction msg will show up.

Mein Auto: 2012 750li X Drive
I had this same problem when I purchased 18" winter rims & tires for my 2012 750li xdrive Msport from a guy here on bimerfest (great deal and solid transaction). The tire pressure sensors weren't right so I had to spend an extra $500 when they mounted the winter wheels for new tire pressure sensors. (owell)

I bought the rims/tires because you can't put winter tires on 20" rims. The 18" rims/tires came from a 2009 bmw 750i I believe.
