    Engine won't start possible PCU/immobilizer issue

    I finally got it fixed after more than 2 months!! All that apparently was wrong was that the fuse box plug was pushed up slightly by pieces of pine tree seeds or something that I forgot to clean when I had disconnected it!

    Hard start after getting gas...?

    Tranny fluid change

    On My 2005 3 I changed the fluid around 120000 miles, and there was no red left at all; probably had never been changed. I did 4 changes of the 3 quarts that came out each time, driving it for a few mins inbetween (after refilling of course). It seemed to shift slightly smoother afterwards...

    Engine won't start possible PCU/immobilizer issue
