I don't have the slightest idea why I am getting these codes. Have you ever seen a 4A72 code? The other two codes don't bother me because I know (or at least think I know) that they are gremlins that only come about once a month. I used to think I was a pretty good shade tree mechanic. Now that I own a 335d, I realize that I don't know squat. There is not much about this car that makes sense to me. I reset the adaptations after CBU to eliminate the CBU related codes. However, I still get them occasionally. I don't know what else to do. That is why I get on this forum and ask for help.
