    General E46 Forum
    Ok so still fighting my ‘01 330i on the dreaded p0171 and p0174. It seems as if I have gotten it down to something with the ac. Call me crazy. I haven’t read anything in any other thread about this. But it only throws lean codes when I’m running the ac system. Any guesses?

  8. Weak Blower

    General E46 Forum
    I've noticed that my blower seems to not change the amount of air that comes out of the vent, no matter if it is on low or high settings. It's blowing cold and hot just fine, but the actual amount of air that is coming in does not seem to change. I can hear it get louder as I increase the high...
