well, got the codes read (finally). Came back with P0171, P0174, P1512, and P1515.
From what I managed to find after a quick search the first two codes definitely have something to do with the DISA valve while the third may be related as well. The last code apparently is not a valid BMW code and would require a better diagnostic tool than what AutoZone has to offer which my friend happens to have but of course, he lost the BMW key. So, any pointers?
Should I change the DISA valve? I mean my check engine light isn't on, these are all stored codes.
