Hello all, a couple days ago I started my M5 with a rough idle and eventually stalled. Started it up again and same issue; rough idle and eventually stalled. I had this issue about a month ago and it was determined that the fuel pump needed to be replaced. Now what? I ran a scan and got codes P0172 & P0175 meaning car is running too rich. Can anyone offer any troubleshooting advice for this problem?
