Bmw fault codes - CD9003 LIN
Hoping someone can help or has some insight. Had a CEL come on this morning, ran a scan (Schwaben by Foxwell) and came up with CD9003 and 121202, see pic for description.
CD9003 - might be the only code missing from service manual. Only one site has info on it (bmwfault.codes) and it is still pretty vague. No idea how to troubleshoot the LIN (local interconnect network) or even where to begin.
121202 - i have a dinan sport tuner, thinking it's related to that or potential charge pipe failure looming.
Has anyone had experience with any of those or do you have any suggestions?
