Look at your wheels. The valve stem are metal on TPMS instead of rubber. If you still cant tell, let the air out of your tires. If you get a warning light you have TPMS, if you don't get it, you don't have it. Good Luck.:)

Do you have RFT?

You can initialize the system the same way whether you have TPMS (pressure sensors) or FTM (ABS sensors). Use the stalk to get to the tire symbol, bit the button till Reset appears, then hold till a check mark appears. Simple, done.

i don get want u say, cuz i follow the manual but there isn't the TPMS initial setting. ( only has like oil, date, time, check control) seems like missing sth. i have RFT maybe mine just don has it?

Are you checking it with the engine running? In my '07 328 with FTM, certain functions aren't available unless the engine is running.

Fwiw, your post is difficult to read with your shorthand and abbreviations. What is "sth"

All the e9xs have some sort of TPM whether it is direct or indirect. to set the TPM the engine must be on, the car in park, or not moving. flip the stalk toggle switch up until you see the TPM setting, stop and hit the BC button until the ACTIVE or check mark shows up. Then just drive.

Anytime you set tire pressure, you should initialize the TPM.

i checked, i only have rubber valve stem and i think i only have FTM but not TPMS. thx

yea, its the indirect version of flat tire monitoring. it uses the dsc for wheel speed to determine if a tire is low or not. you should still have the monitor in the stalk though.
