Just going to leave this here as this forum is my personal go to for my minis issues.

Went to get a smog check they said it could not be performed because I hadn't driven enough sense I changed the battery, the O2 reading was incomplete. Called the dealer, must have caught the new guy at the dealer, as stated and worked like a charm

Drive 55mph keeping your rpm between 2500 and 3500, fuel tank has to be between 3/4 and 1/4 full.

This forced the computer to run the O2 diagnostic wich was reading incomplete when i tried to get it smog check.

I was told to get behind a big rig because there max speed is 55. well i just angered everyone passing me ( including big rigs) for about ten miles both directions went back to same smog place and they said it was ready
