    General E46 Forum
    This one has me stumped: The other day I started the car in the morning and it went immediately into Limp Mode.

    I have a 1999 323i that I bought used, and it has around 129k right now.

  15. Check engine light will not come on.

    General E46 Forum
    Hey guys, Had a smog check recently and it failed when the check engine light wouldn't come on when they told it to.
