Hi Folks,

4-5 days ago i changed my brothers car battery. E90 2008 328i and while coding the new battery i clicked on Process Car by mistake and i think it reset all modules. After which i started having issues like car will lock itself on door close and then on random occasions it wont open with key fob and then key fob suddenly works. Now this morning after 3-4 days of this update, the car isn't starting. I hear a click and then nothing.

I tried to reset the CAS from VO on which i get COAPI 2063 error. i did the reset with empty MAN file and it works, however car is still not starting.

FYI the car key was programmed by a lock smith as the original was lost. So key is new. Battery is also good as its new.

Please help me out .

Check the codes with INPA.

I checked the car with INPA and i am seeing A0C8 & A0B4 codes. Any idea why i am getting this? Any solutions.

Run functional jobs F3 and F4 and see what Inpa says about
the control modules. See the bimmerprofs link below.
