  2. Secondary Air Pump Not Running When Vehicle Starts

    General E46 Forum

  3. Observations about the cooling system

    General E46 Forum
    I purchased a 2002 325i 5-speed with 120,000 miles in May. Everything on it worked just fine. But it is a 15-year-old BMW, so I have replaced nearly every part that could go bad in the foreseeable future (coolant system, gaskets... *see below for full list). I have had trouble bleeding the...
  4. What's this hose called? (help...)

    General E46 Forum

  6. Vacuum Hose Sizing?

    General E46 Forum
    Hi everyone, So I've been tracking down a vacuum leak on my 2001 330i for a while now, and I just found a split in the vacuum line between the Secondary Air check valve and the vacuum control switch (3/4 in the attached diagram). Ideally, I'd like to replace all the little lines back there...

    Hello fellow fanatics! Just now changing my secondary air pump hose and I'm checking to see if it's working (ie checking to see if the valve needs replacement as well). I connected the new hose to the valve part and blew through it while the car was running but I wasn't able to push any air...

  10. "Double" intake 330i?

    Driveline, Engine & DME Tuning
    Well, I've been shopping around for intakes and noticed a lack of dual filter options. I got to thinking why-not or why this may be and figured a double option must conflict with the most effective way to draw air or poses a maintenance challenge. Does anyone know why I'm unable to find...
