Thanks to nolaman1970 for linking the TIS page here.

Please see below based on your build dates. The first step is to remove TPMS RDC module by unplugging it. This system is more accurate but can get costly with extra sensors when multiple sets of rims or in my case, racing rims that were not designed for TPMS.ĭuring my research, I found a thread that describing exactly what I wanted to do! Thanks improvius for documenting this awesome finding! TPMS = This uses sensors in the wheels and connects to a main RDC unit in the passenger rear wheel well (at least for LCI E90 2010+). All tires drop to 29psi instead of set 33psi) The con is if there is a decrease in tire pressure across ALL tires due to not checking, it will not detect that. This will determine if there is a flat if there is a large deviation. I figured the economical decision is to ditch the whole wheel sensors altogether and revert back to the Euro E9x/Pre-LCI E9x FTM system.įTM = It uses the speed sensors in each wheel and compares rotational speeds to check if there is a differential between wheels. I personally didn't want to spend the extra money on a second set of sensors. There are plenty of guides out there for this!

All of this working prior to this DIY! This guide is not designed to teach you how to use NCSexpert.
