I have a 2002 745i and the idle was going below 500 rpm at times, especially at stop lights, signs, etc. Even though it was smooth during driving, the drop in rpm was annoying and it seemed as though the engine would shut down, then jump back up to 600 rpm. I took it to my local BMW dealer and they adjusted the idle to 700 rpm at rest. I haven't had any problems since. A simple fix. Otherwise, could not be more impressed with my Bimmer!!!!

UPDATE...May have found the fix! Downloaded version 26 software upgrade, followed instructions for the upgrade exactly, and now(cross my fingers)the problem seemed to fix itself. Will see how it goes in the coming days.

Thanks for the reply. I will relay this information to my dealer. The car has been with the dealer since last Saturday and the dealer is working with BMW b/c they cant seem to figure it out.
Also, does your rpm slightly jump up when the AC is on? When my AC is off, at rest my rpm is sitting at .5. Once the AC is enabled, the RPM jumps to about 0.7 (and stays there till the AC is disabled). Just wanted to know is this was normal or not. My wife has an 01 X5 and this behavior doesnt occur on her vehicle.

I can't see why BMW has to keep your vehicle for such an extended period of time just to check the idling issue - seems strange. At one point before my local dealer fixed the problem I had with my car, the tach needle was "idle hunting," going up and down below 500 rpm, especially when I had no auxiliary equipment in operation (A/C, defroster, etc).
My rpm does increase to a little above 700 rpm when the AC is on, and once it is off, the rpm goes down to around 600 rpm. I believe this to be normal due to increased load on engine when the A/C is turned on.

So I called my dealer asking if the tech has tried adjusting the rpm at idle to 700 rpms at rest. Service rep indicates that the tech working on the car is the best they have and is pretty sure he's tried it - whatever. Service rep mentioned they have a pullman case opened (not sure if I heard him correctly though - could be called something else) with BMW on this issue.
At least the dealer gave me an 06 530i (as a loaner) with the sport package which handles great. Now I regret (and only regret so far) not having the sport package on the 745. Vehicle still handles great, but Im sure the 7 woulda been a lot more nimble and not feel like the boat it is w/o the sport package. Next 7 series I purchase will definitely have the sport package.

Hope you get the problem fixed, even though driving an '06 5 Series isn't bad either!
The sports package on the BMW's are the best - firm, yet comfortable ride, and with the 19" wheels for the 7 Series, the look really catches the eye, especially chrome 19's!!

In some cases the warranty for an 02/03 is 6yrs/100k. Not sure so check with your dealer. Lost of times its an software update. Let us know what happens as I was thinking about trading in my perfectly good Lexus for a 745, but I can't bring myself to do it given the ongoing issues with these models.

I went to LeighBMW in Raleigh last week and thought about trading in my Lexus for an 03 745. I took the 745 out for a test drive, and honestly it was the best car Iíve ever driven. From what Iíve been reading, however, itís not the best to own. I canít even imagine having some of the minor problems owners incur, let alone a major one. The car had a little over 40,000 miles on it, and the salesman told me about the 6yr/100k warranty, but I canít bring myself to purchase the vehicle. I keep thinking, what if this car turns out to be a lemon, and I traded in a perfectly good vehicle with no problems? For the price, the 745 should be much more dependable.

How was the 745 a better driving exp compared to your Lexus? Did your 745 come equipped with the sport package? I'm really picky when it comes to wind noise etc, and I think my buddies lexus has a quieter cabin than my 03 745Li (but barely). And when my car is idle, it is definitely not as quiet when compared to the Lexus. Of course when I drive my car, the driving exp is a lot more enjoyable

Hi sadatx, there was a little more road feel with the BMW, but I haven't decided yet on whether to trade my car in just yet. To tell you the truth, I'm a little concerned after all of the reading I've been doing. My friend has a 325i and he's never had a problem with it. Of course, it doesn't have the iDrive and much of the technology the 745 does. What has your ownership experience been like with the 745? It will need to be a lot more dependable for me to make a move. An extended warranty is one thing; but time and inconvenience is another.
