Dont know what these codes are p1749 p0740 on 323i codes given by autozone

Go to autozone or similar and have them scan vehicle

code p 1625 refers to CAN databus, TCM--incorrect signal===causes --TCM trouble code/s stored---TCM incorrectly coded---wiring---matching resistor in ECM
I don't have a listing for code p 1749 but codes 1748 and 1750 are concerned with TCM defective and voltage supply low
so after you check the wiring and connections form the transmission you have 2 options
use a known good ECM to replace yours ( will eliminate any ECM faults)
and/or replace the TCM module on the transmission

the starter could be bad you can take it in to autozone to have it checked. it could be a fuel delivery problem, your fuel pump might have given out. if these turn out to be ok than take it into autozone to have them look up the codes on the computer. (i dont think they will come out to the vehicle but if you can get it there somehow they will do it for free)

What is the code? If you dont know, go to autozone etc they read the codes for free

What code did autozone say you had. Ballast resistors have been used in cars since the late 1970's.

I'd go to an auto parts store that will check for any diagnostic codes free of charge (autozone and advance auto both do) and if you have any codes, list them here and I can tell you their definitions and the most common solutions to fix them in detail if needed

pic up a manual at the zone-it has the standard list what each code signifies-remember they dont always tell u the solution cause physical problems in engine require inspection

this codes made from automatic transmission, go to work shop to check

you need to pull the error codes in order to know what your issue is

I dont know if you can ODB self-diagnostic, but if you can go to an auto store (Advance, Autozone, etc) and use their code reader (It's FREE!).
