Hi I have BMW 523i 2006. i have some questions. what kind of oil i should use it?
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.

are you sure you need the crankshaft position sensor changed. it is at the back of the engine i believe, but.....
check for a wet ecu first... read the note on e36...
the ecu compartment is under the windshield on the passenger side on E36
you gain acess to it under the hood....
this compartment gets wet, the ecu lays on a flat surface in that
compartment.
the bottom side of the circuit board gets wet and starts corrosion.
remove the ecu, take the bottom plate off, clean the bottom of the circuit
board with alcohol and a soft tooth brush.
you should be able to see the signs of corrosion or conductive build up.
this gunk bridges solder points doing all sort s of wierd things to your
car, including false sensor readings from asc/abs controllers and other
sensors....
all the way to engine failure and worst case burnt and shorted wiring
harness.
I'm on my 3rd ecu, took me and the repair boys a few years to figure this
one out.
BTW: i would get that ecu mounted above that flat surface, use some sort
of standoff to raise it so that it is not laying in the wet.

Check out if any headlight bulb or ac or ac fan remaining On even after you turn the car OFF.if its remaining ON then that must be draining the car battery.But if nothing is remaining On after you turn the car OFF then check the Ignition switch and its connections.Also check for 12 volt at the ignition switch connections.In many cases the ignition switch of the car goes bad.the ignition switch is part of the car where you insert the car key to start the car.if the switch is internally faulty then it will not turn the car OFF ,even when you turn it OFF.Also check the connection between battery to starter and connection between battery to alternator.If any of the connection is loose or not connected properly the battery will get drained.If the battery is too old then it can be actual fault of the battery.In many cases when battery gets old,it stops holding its charge and gets drained in few hours of charged. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.
