Hello. I took delivery of a 328i today. When I unlock the door(s), I notice a high-pitched noise coming from somewhere under the hood. When I get into the vehicle and shut the door, I cannot hear it. When I go back outside the car, I hear it. The engine is off the whole time. When I lock the door)s), the noise goes away after about 30 seconds and I hear a gentle "click." Could this be coming from the engine immobilizer or alarm system? Anybody else experience this? One guy I talked to suggested it could be the fuel injectors, but the engine is "off" when I hear it. Grateful for any input. Thank you!

Does the 2000 323i engine have a 150,000 factory warranty like I've read about for the 2001 model?

Hi, This thread made me think of some noises I hear upon inserting the plastic key in my '07 335xi. The engine seems to do: "Oh Boy, OH BOY! Someone put the key in the little slot! I better try to warm up the oil, start this-or-that pump, and get ready to REVVVV!" The whirring, etc, settles down within 2 to 4 seconds, and no bad noises come through. It all sounds normal, and good, from my perspective. I like the idea of the engine anticipating what it will be called to do. This sounds like some proactive thinking on some Munich engineer's part. Now, if only someone could confirm that this is really what is happening, I'd feel better. To me, it would be like having intravenous espresso only seconds after waking up. How nice would THAT be! xeye |

I wonder if the noise you speak of is the fuel pump  My '90 E30's fuel pump whirrs before the car turns over.

Hi, In my '07 335xi, there are two small ducts just below the hood hinges on both sides of the engine compartment with removable screens. Does anyone know what they are for? It's hard to believe they are air intakes, yet that's exactly what they seem to be. I hope they're not intakes for the turbos. The thought of tiny little bits of leaf in the innards of my delicate engine makes me uneasy. My issue is that the car seems to attract leaves, maple tree seeds (little propellers?) and other flotsam in the gaps at the top of the hood below the windscreen like no car I've driven before. The junk gathers in particular in the wells where these removable screens sit. I try to remove whatever I can, but I'm concerned about the impact if some of this debris should fall into the duct wells in the minute or two when the screens are removed for cleaning. Because it's a small area cluttered with vacuum cables, it's difficult to ensure nothing falls in. Another complaint is that the fluttering of trapped dried leaves in the wind sounds like I have baseball cards clothes-pinned in my spoked wheels. Unfortunately, I park beneath an enormous maple tree in my yard and the damned thing sheds every Autumn right on my car. Couple that with the dozen or so bird feeders in the back yard and you can imagine what it takes to keep my shiny sortof-new car clean! Any ideas about the air ducts? xeye

| Last year I bought a set of snow tires and wheels for my 2003 M5, and then decided I was not going to drive it in winter. Does anyone know what other models of BMW the wheels will fit? I want to sell them... Thanks! | |
