If my notes are right a 1999 523I filled through the transmission dipstick with a funnel. The only other fill was if the transmission is removed.

There won't be a dipstick. You have to pull out the plug on the side of the transmission while the car is level and the transmission is at normal operating temperature. This is pretty tough for the average guy to do in his garage.
My daughter has a '97. We just take it to a shop and get the fluid replaced every 50k miles and so long as it does not leak, we don't worry about the level between changes.

there is no speedometer cable on these cars,they have wheel sensors on all wheels,check and replace senor/sensors. will also sometimes throw abs and ats lights on dash.not to difficult to change for a diy person

sounds like the crank sensor is bad.

To be completely honest, I know so few about the 2005 BMW's, but the battery location should be simple.

Typically they are located under the hood, usually by one one ofthe hood hinges. However, BMW has been know to put some of them in thetrunk (E46 325i). I have also seen some of them below the rear seat as well (Serie 3). Thebattery may have a cover over it, so it may be a little harder to see.

From my BMW catalog it shows it should be in the trunk, on the passenger's side. See this site: BMW Select

Hope helped with this (remember rated this help) Good luck.

your car is not suppose to idle at 500 rpm . 800 to 950 is the proper idle, unfortunately it is controlled by the computer. have you checked the idle speed control valve? also check the air flow meter
