01 740i battery swap/starter

Hey I have a 01 740i and when you go to start it, all it does is click. When talking to the dealer there were no help. I have tried to charge the battery and see if that helps and it hasn't. The dash lights come on and it seems as if there is enough power to start it, but its clicking. Does anyone know much about the starters? Is there any tricks in swapping them out? Will I have to worry about computer issues if I leave the battery unhooked more than 4 hrs as the dealer says? Any help would be great.

First things first. Check the battery terminals and make sure they are not corroded. Tighten both terminals if necessary.

If you do not know how to unlock your OBC...do a search on this and/or other forums so that you can determine your batteries amperage at rest. These cars require tremendous amounts of power...you may in fact need a new battery if the car has the original battery. Do not go to the dealer for this if you have other options.....you should be looking for a Duralast 49L I believe, from Autozone....much cheaper.

If you are thinking of jumping the car, use the terminals in the engine compartment.

Starters in these cars (especially the '01) are generally not the problem......usually it is the battery itself.

Good luck.

Mein Auto: 1999 BMW 740i
Hey Jake does that same advice apply to a 1999 740i? My car has been sitting for almost three months, I have probably started about 3 or 4 times in the time span, but when I went out to start it the battery was completely dead. In attempting to jump the battery, all lights, cameras came on but all I got was the click, click, click. Could it be I need to get the battery charged?

first off, what are the cranking amps reading at after charging the battery. this will tell you quickly if the battery is bad, or to look elsewhere. about the battery, i dont recommend autozone batteries unless you like wasting money on crap. their batteries are some of the worst i've ever seen, of them i've owned and in customer cars.

honestly, the E38 is a well made vehicle, i'd almost swear it wont be the starter. especially if it still clicks. have the battery test at a local auto parts store, they should give you a free test at most places.
