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! | |
According to what I've read in ROUNDEL, BMWCCA's monthly magazine, wheels from an E39 BMW 5 series will only fit an E39. Something about the offsets being different.

| The ducts you are referring to are for the brakes If you have a 335i coupe with factory oil cooler in the passenger front wheel well, then that duct is for that cooler. | |
