Something is draining the battery on our 2002 bmw z 3. The battery and alternator checks out good. What could be the problem??

The problem is that an electrical component in the BMW that should be dormant when the vehicle is shut down is actively drawing power.
The only way to track it down is to have tests run to see which circuit is drawing excessive power because there are numerous components that might be the cause.

Stick or automatic? Either way, clutch or transmission cables out of adjustment or bad clutch/transmission most likely, have to bring it in to a transmission shop to be properly diagnosed.

12 Codes 313,300,444,305,303,306,302,301,304,174,171 does anyone know what the issues are? also My car shakes & shuts off if I'm at a complete stop for too long but drives fine on highways.

Sounds like you may have some ignition/O2 sensor or even cat issues , as these codes range from missfire to lean bank problems how many miles are on it? Whenwas the last tune up performed?

Remove battery terminals and clean both posts and terminals
with sandpaper until you see shiny metal. The black coating is lead sulphate which has a high resistance to current flow both into and out of the battery. Also check the battery in you key as the immobiliser may not be reading it.

I have a bmw 3 series and have been having trouble with the car not starting. it has had a new battery and last week a new alternator but now seems to be worse

If the battery is ok and the alternator is ok u probably have a battery drain on the vehicle to test this u will have to put a mulimeter inline with the positive battery lead and check for amp draw. When checking this the ign needs to be switched off 0.05 amps is the most u should read if it's more than this pull out the fuses from the fuse box untill it drops this is how u find out what circuit the drain is on

My 2003 BMW 330xi won't start. There is absolutely nothing, not even a click. Battery is fine, and jumping it did nothing. Had the solenoid replaced last year.

I actually had a problem with my KEY.. will yours start with the spare key? For me, the electronic ID sequence on the key isn't recognized in the ignition.. it still manually and remotely unlocks doors, but won't start the car. The spare key (which stopped remotely unlocking doors a while back) CAN start the car...

How do you pair a phone to a bmw 330xi

go to verizon, by two phones, now you have a pair. Then you can call yourself and you have paired the phones to any car, not just a 330xi.

Most states have outlawed phone usage anyway. So that was you in the slow lane weaving all over the place trying to text, use the phone, call the wifes girlfriend at the office.

But you will be able to call the collision repair shop and tow truck from one of your two phones.

2001 530i battery drain/alternator question

first off never never never trust a tow truck driver they are idiots, it takes a BMW 15 mins to go into a sleep mode before a draw can be mesured, as for the dealership they should have caught that using the Midtronics batt/alt tester that is standard from BMW 2.5 years for a batt replacement is reasonable especially in a BMW based on the high demand on the electrical system, I just replaced an alt on an M54 enginge just today so they do go bad, have them give you a print out from the midtronics with your VIN on the printout showing your alt is bad and what the batt is.
