TPMS compatibility issue
I installed some 18" 219M wheels today that came from a 2008 M3. I expected TPMS incompatibility but no warning light came on. When I attempted to reset the TPMS, the dashboard display read: "ACTIVE."
The reason I'm posting is because I was planning to get 2011 TPMS modules installed today, but ... now I'm not sure I even need to spend the $? Any ideas or experience is appreciated. |

Why don't you deflate one of the tires to see if it is working properly?

Maybe the 1M uses the old TPMS system? I know from Sept/'10 (2011 M.Y.) 135i model cars... BMW changed the TPMS freq. Sounds like you are good to go - with the TPMS you have in your "new" (used) set of wheels. Quote:

That's what I thought too but I drove on them for about 30-40miles before anything popped up on the dash. I had the TPMS' swapped with the original 2010+ ones that came with the car, and the ones removed were definitely the older 07-09 ones. Both old and new sensors were marked as running on 433Mhz.
FWIW my car was an 08/2011 production. Quote:

It may take a few minutes and maybe longer if your other TPMS sensors are close by. When I'm at the track and swap to my track wheels, the inactive message does not appear until I've left the paddock and am on the track.
So the bottom line is make sure your car is not reading your old sensors and reset your TPMS.

Thanks for the feedback everyone.
I called the dealership and they told me that if after resetting the TPMS that it read "ACTIVE" then the sensors were compatible. It turns out that I didn't actually reset things by keeping the button selector held down. When I did that, then it just kept reading "RESETTING" in addition to displaying the TPMS warning light. I had the new sensors installed and the light went out. I just found it odd that it wouldn't tell you right away. |
