TPMS computer location
Anyone know where TPMS computer is located on 2008 1 series? On 3 series it's in the trunk on passenger side, but I check there on my 1 and it's not there.
Thanks Art |

Originally they blamed my aftermarket subs that I installed for my TPMS failure. When they fiddled with removing my subs the TPMS reset, but it went out at the dealership when I picked my car up. They finally traced it to poor wiring connection at the TPMS control unit, and when fiddling with the subs, mainly the passenger side, it was enough to nudge the wiring back into place. So, it's in that location. I don't know if you can access it by removing the subs and sub mounting box, or if you have to go under the car. Sorry I can't be more exact than that. After some research, it seems BMW is using "gen 3" TPMS, as of 2010 model year. Pre gen3, the TPMS consisted of a sensor in each tire that then transmits a signal to a receiver in each corner wheel well that then sends a signal to a central control unit then to the ECU. The new gen3 system no longer has a receiver at each corner wheel well. So, it's a tire sensor that transmits to a central control unit then onto the ECU. Less parts, less to go wrong. |

I got a 2009 135i and am looking for the RDC controller to disconnect it and disable it by coding.
I looked in the location theArt suggested. There is a controller there, but not the RDC controller. Any suggestions where it is? |

After reading out my VO. I found out that there is no option 2VB so i guess no RDC controller. But in my CIC there is a option for Tire pressure. Does anybody knows how this works. I thought all bmw's with run flats have the TPMS system.
thanks |

Only US spec cars have TPMS in the wheels and a ECU in the car. All other countries use the ABS computer to monitor wheel speed/drag when a tire is going flat. So I would suspect the SW is built into the ABS ecu on those cars. |

Are you sure we have pressure sensors in the tires? |

One quick way to tell is that US cars (with the TPMS) have a metal valve stem, while ROW (rest of the world) models have a rubber valve stem(w/abs tpms system).

It is mandated by US law. We can thank Firestone tires and Ford Explorer's for this. You could always let some air out of one of your tires and wee the warning light go off(on). |

I have a 2009 E88 and I've been struggling trying to find the RDC TPMS receiver. It's been coded out completely so all I have to do now is remove it and I've been trying to remove it for about a month.
Any suggestions? |
