I've been trying to code the tire pressure light off of a 2009 535i. Worked perfectly on my e92 but now I am having troubling trying the similar code on the 535.
I was able to pull the fuse, delete TPMS from the VO and code it back to the CAS. Usually then after I FA_write to the FRM as well. I know the 535 has an LMA module and not FRM module, but it does not let me read or write to this. It tell me that "no connection to the ECU".
Anyone have any idea why this is? or if maybe I'm doing something wrong?
