    You need to test the throttle position sensor(TPS) as well as the idle control valve(ICV). The test procedures are dead simple assuming you have access to a digital multimeter. I'd strongly suggest picking up a copy of the BMW E36 Bentley Manual if you plan to perform maintenance and repairs yourself; Threes of that vintage are actually quite easy to work on.

    I have a 2001 330 Ci automatic and have recently noticed a shimmy in the front end when making turns. I've also noticed a little rattling noise in the front end usually around the right front tire. Anybody have a clue?

    The car has always had a tendancy to stall at times just after it's first started and in slow speed stops and starts.

    Thanks in advance for your help.

    With the displacement on the 2006 330 and 325 engines being the same, how can one tell for certain if the correct engine is in a given 330?

    The reason I ask: I have a loaner 330i while mine is in the service center (again!) and the loaner feels more powerful (much more powerful) than my car, especially in lower gears. The same throttle pressure that would get my car off to a healthy but reasonable acceleration results in the loaner positively leaping off of the line. At 3/4+ throttle, my car feels like it hunkers down first and then gets off to a good clip; the loaner roars off without any hesitation. Both car have similar mileage (loaner = 1900, mine = 2200). Mine has a sport package; the loaner does not. Both are AT.

    Could it possibly be the wrong engine is in my car??

    "Could it possibly be the wrong engine is in my car??"

    No. Most likely explaination is how the 2 cars have been driven. Odds are the loaner's been driven more aggressively than your car. Software adapts to driver's habit to optimize performance.

    Went to the local BMW parts window and asked about refills for the 2002 325i. I was totally blown away when he said they were $2.90 each. New Rain-X blades - which don't have the proper connection insert are $9 a pop at the big-box stores .. Anco about the same ... Trico doesn't list the car. So, we will try the BMW product and see (hopefully).

    I found a similar deal with the oil filter inserts. The STP filter at Autozone was made in China and cost $10. The BMW filter cost $6.88 with my CCA discount and was made in Germany.

    Interesting ...

    This would be consistent with another posted I read a post here a while ago about the break-in period for a previous model 5-series ... the owner had driven it aggressively from the beginning, and subsequently a technician driving the car some months later noticed it displayed considerably more power (thought the 530 performed like a 545).
    So is this sort of phenomena dynamic or pre-determined by one's behavior during the break-in period? (i.e., if I start driving my car more aggressively, will it "loosen" up as well, or having been pretty mild on the petel during the break-in period have I permanently trained timidity into my car??).

    Software constantly updates so it's dynamic, but it does take some time. My car wasn't truly "broken in" until 20k or so.
  • I NEED TO FIND A ECM FOR A 1995 325i. ANYWAY,THATS THE NAME THE MECHANIC GAVE IT.(ELECTRONIC COMPUTER MODULE?) ANY HELP WOULD BE GREATLY APPRECIATED.
  • jamieljamiel Posts: 1
    I have a 2004 BMW 325i, w/ about 10k miles on it. I had a strange situation yesterday when I tried to pull my car out of the driveway. It seemed like the engine was shaking, and the car is about to stall. When in Park and idling, the car shakes.. almost trembles. If I press a little on the gas, the shaking stops. Then a few seconds later, as the rev goes down, it shakes. Things don't "feel" right when I drive, as if a certain oomph is missing. My "Service Engine Soon" light is on.

    I'm not sure if this has anything to do with the tons of rain we got in NYC past few days. I drove my car a few days ago and everything was fine. Any idea what the problem is? The dealer is about 20 miles away, is it safe to drive? :confuse:

    Any help is highly appreciated

    The post about the 530i that you are referring to is one that I made a week or two back. Just to keep the tale from growing, the BMW technician compared my car to the then available E39 540i (non-sport, non-6-Speed I assume), not the newer/faster 545i.

    As far as aggressive driving begetting a faster and more responsive car, my thinking is that there are two separate issues here.

    1) The drive-by-wire throttle control system. Over a period of two or more weeks (I forget the exact period, and whether it is calendar time or on the Hobbs Meter (engine hours)), your car's ECU learns your driving style and adjusts the throttle response accordingly. I've read that some recent Audis could be forced to have their memory purged thus speeding up the learning process. The steps to activate said purge were something like, a) turn the ignition on but do not start the car, b) hold the throttle pedal to the floor for some number of seconds, and c) release the pedal and start the car. Will this work on a BMW? Unknown, I suppose it depends upon whether BMW and Audi use the same supplier for their throttle control system. If you want to try it out, check out the Audi A6 discussion and search for posts from markcincinnati, or I suppose you could just post over there and ask him for the procedure.
    2) The physical break-in of the engine. When I was a car crazy kid growing up in the Birmingham/Bloomfield Hills area of Michigan, I had lots of friends whose fathers were engineers for the autos (gee, what a surprise given the geography). I heard from more that one source that the fastest engines were broken in hard, hard as in leaving the transmission in second gear and driving down the freeway for fifty miles (back when the speed limit was 70 and cars drove 85). Supposedly this procedure conditioned the internals of the engine to run faster with less resistance, or some such bilge. Do I believe it? I'm not sure, but so far at least, my cars have all been broken in that way (well, not quite that hard) and they have all seemed to be quite fast compared to other like models.

    Best Regards,
    Shipo

    First, turn off your Caps Lock
    Second, contact ProgRama. They can supply ECMs on an exchange basis.

    Having test driven the 330i prior to placing my order and having spent a week in a 330i loaner, the first few weeks I drove my own 330i, it felt as though they'd given me a 325i with 330i badging. Of course I knew that wasn't the case, but I was at a loss to explain the relative sluggishness of my new car as compared to the demo car and the loaner car. In the case of my car, there was an initial hesitation upon acceleration, and the car didn't wow me with acceleration even after it got going. Now, 6 weeks and 3,000 miles later, it's much better. The hesitation is gone and a good acceleration rush is there for the taking (though still not as much of a rush as I got with my G35). I chalk it up to "breaking-in." Probably you will also see an improvement in time. But why should it take time? I don't have the answer. My G35 was fast right from the start. I'm surprised that my 330i was not.
  • Thanks for your help!!! Have you had any experience with ProgRama.? Thanks again!!!
  • If I had to guess... I'd say a bad camshaft postion sensor... My '03 had the same exact symptoms...

    I wouldn't drive it that way.. call BMW roadside assistance, and they will flatbed it to the dealer...

    If it is the sensor, it isn't serious.. a fairly quick job..

    Hi there. Yes, I remember now that it was your post.

    This is fascinating to me. Intuition would tell me that such aggresive break-in would damage the engine in the long-run, and with that mind set I've drove the first 1200 miles very timidly (didn't take the car over 65, never over 4500 rpm). So maybe if I drive a little more aggressively, the car will loosen up ...

    When I read your original post I was astonished that a technician (to say nothing of an average joe) would take notice of the perforamcne differences. Then I borrowed this loaner and experienced it myself.

    I just hope this all means that the same performance potential lurks underneath the hood of my car ... just needs to be slapped around a bit :)

    ... well, I am glad my concern that I might have a 325 in 330 clothes isn't a thought that's occured only to me (my wife's certain I've been driven paranoid by the problems I've had with the purchase/prep of my 330).

    Thanks!

    Knock on wood, I've never needed to use ProgRama. However, several of my friends have dealt with the company and all have been quite satisfied. By the way, you DO know that you can swap out the ECM yourself, right? It takes all of about ten minutes-tops.
  • NO!! I was unaware of that, I would be very, very interested in the process. "THANKS " again , YOU have been most helpfull.
