Halogen to LCI Bi-Xenon Coding.
I’m in the middle of Halogen to LCI Bi-Xenon conversion in to my X3, F25 2015 (forgot to order Xenons:-(
FRM module is FRM3 (as I checked the OEM parts, it should be the same module for halogen/Xenon/led).
I downloaded original wiring diagrams and changed some pins at headlight connector+ frm3 connector.
Than i VO coded FRM with 522. Then i was searching for headlights modules in ESYS (TMS). There is nothing new, still all the old ECU’s only. INPA shows error : HW-Kodierung und SW-Kodierung unplausibel.
Now the question: Should I VO code except FRM also some other module ? (CAS???) or what is the failure code telling me. It seems to me there is coding missmatch…
Thank you in advance for the answer,
Hi,If the installation was done correctly then it’s only a coding problem. What build year is your car? Changine Manufacturing date could be needed.
