Technical Error Codes 2FA3 and 2A18

[zcchen]

Just installed PR stage 2 walbro lpfp and bimmerlife R8 coils along with stage 2+ flash from MHD. My car is a 1M with FBO. When I went out for a test drive, the car pulls good but these two codes showed up:

2FA3: Coding Missing?
2A18: DMTL diagnosis module tank leakage, heating: input signal

Please help me understand these two codes!

Thanks!

Did you check the box for BL coils in MHD?

Turns out, 2A18 is for DMTL, a module that physically doesnt exist in my car. It is a module unique to the USDM while my car is a Chinese-spec 1M. Somehow the codes for DMTL was activated when I flashed my car. Per instruction form Martial found online somewhere else, I re-flashed my car and this code went away.

However, the 2FA3 code persists...

Clear it a few times with MHD and drive some, it should go away. It also doesn't effect anything.
