Have you coded out your TPMS?
Who relies on their TPMS? I keep a tire pressure gauge in my trunk and check every so often (2 - 3 months, or when I switch wheel sets). I am thinking about coding out my TPMS as I am looking to get a new set of tires.
Why? Well, with each set of wheels I collect I have to add the TPMS modules and I feel that I take care of this manually. My car is a 2011 and don't the TPMS module batteries eventually die or wear out? What is there useful life? Hoping I can avoid an unnecessary dash light and a trip to the tire mounter/purchase of another set of TPMS modules. Any considerations that I am not thinking of?

Thought about it. Macht and Schnell have a module to plug and play. It can't just be coded out from what I researched.

Got mine coded out when I removed EDC. Just unplug the modules after coding for both TPMS & EDC if I'm remembering correctly.

Do the TPMS sensors actually wear out? Or is that a rumor I picked up on the forum?

Macht Schnell TPMS Delete Module: https://www.turnermotorsport.com/p-2...RoC5_UQAvD_BwE
Product Details Tire Pressure Monitoring System (TPMS) is an electronic system designed to monitor the air pressure inside all the pneumatic tires on all BMWs manufactured since 2006. Within a predetermined pressure level, a RF signal (433mHz) is sent to each of the receivers located in the wheel wells. These systems report an error message to the driver when pressure is low. Battery-powered Radio Frequency based TPMS have several disadvantages. Batteries eventually become exhausted and represent a maintenance cost to the consumer. Batteries are chemical systems with lifetimes that unfortunately perform very poorly in extreme temperature environments typical of North America and European climates and in aerospace applications. In order to conserve battery life and to conform to various country's communications authority standards for short range radio communications, the power levels of battery powered TPMS are kept very low. As a consequence of these very low power levels, the construction of certain steel belted radial replacement tires and vehicle metallic geometries can block the low power signal transmission paths. The so-called total cost of ownership for direct systems is much higher than for indirect systems due to battery and wheel changes and broken/damaged parts. Replacement TPMS sensors from your local dealer can be in excess of $300USD/set with the lithium batteries mounted in the sensors with a 5-6 year shelf life. Aftermarket sensors are not generally reliable. For those that have multiple tire sets for the track, this is simply not practical. This TPMS/RDC Emulation Module installs in less than 15 minutes and will fully emulate a full-pressure TPMS signal. The module can be activated/deactivated by lifting up on the driver’s side window switch for +5 seconds with the key off. Macht Schnell Macht Schnell TPMS/RDC Emulation Module features: - The ability to run racing tires/wheels or other environments in which TPMS sensors are not compatible - Compatible with iDrive and non-iDrive systems - Easy 15-minute installation process with no wire cutting - Proper emulation of the TPMS/RDC monitoring system - No dealer visits or coding required after installation - Completely removable at any time

Doesn't BPM do remote coding for this?

You can code tpms out yourself
I've removed it from both M3's although I've left it active on the X5 I have like 6 sets of wheels for the M3's. I'm definitely not going to have that many tpms systems floating around! |

Could someone send me a picture of how the TPMS screen looks in your iDrive? I have a 2011.5 M3 but it's Canadian and it didn't come with TPMS only RPA. This system knows when you have a flat by comparing rotation speeds of individual wheels.
I know I can code the regular TPMS on but I'm not sure if I need any other modules besides the sensors. I don't see this as a pain the way you guys do, and I think constant monitoring of pressures for each wheel would be something I want to retrofit. Thanks. |

Exactly, I am not going to keep adding TPMS to my wheels... pointless for me as well.

I couldn't tell you... coding is a bit of a PITA, but all the guides are out there!

I battled with transferring pressure monitors from wheel to wheel in the past. Finally decided to code it out and life is a lot easier for a guy who has multiple sets of wheels. I used Alex at Alpine. He has done a lot of coding for me and I definitely recommend him.

Bumping this. Got new wheels and want to code them out. I have an 09 e90 lci car with the old style sensors and no iDrive anyways so never got much use out of the stock tpms. Any idea where they are located in my year model?
I've seen threads about changing the VO and coding certain parameters...mostly on e90 post and an x series thread |

Best option is to code out RDC (TPMS) and remove the module.
Then code to enable FTM (Flat Tire Monitor) which uses the abs sensors. Rest of the world uses FTM, only US law requires the TPMS sensors in the wheel.
