I got this e90 and it had a few lights that i was willing to take on, it has a tpms light, so i automatically got new sensors installed on the wheels, i reset the code and the light came right back on, i drove the car for a few weeks seeing if itll go off on its own but nothing, the code i got mentioned it could be rdc module or even the harness for that module/maybe reprogram it, not sure what to do, this is my first bmw and am just tryna get it in a good condition

Code the car to use FTM instead of TPMS and all of your troubles will go away. FTM was used in the early cars and the rest of the world, instead of having the $$$ radio-frequency sensors and receivers it just uses the ABS wheel speed sensors to detect the difference in rpm caused by low tire pressure.

Lots of instructions on how to do it, including a post just in the last couple days, but when I had a TPMS sensor fail in my car, I just did it the easy way with ProTools. They have a canned routine for this built into the software. The hardest part is pulling the right fuse or finding and disconnecting the TPMS unit. If you don't have iDrive, just pull the fuse, do the coding, and be done with it forever.

But if you really want to fix it, I would start by finding the receiver module and checking the wiring. On some of these cars it is pretty exposed under the car and can indeed get damaged. Annoyingly, there is a wide variety of places where BMW stashed the thing. I never did find it on my 1-series convertible.

My RDC on my 2011 e91 is tucked away under the right rear wheel arch protector.

Not sure about the e91 but the location of the RDC Module in my e88 is in the rear right trunks corner next to the Go passive module behind the wheel liner. Check for water intrusion. Both of these modukes are exposed to water and moisture.

Yeah my 06 e90 has the FTM module. Good!! 😌
