where are the possitve and negative battery terminals located on my 2003 330ci?

Answer 1

The positive side is always red.

Answer 2

On this car the battery is most likely at the trunk, now there is a cable for the positive runs from the trunk all the way to the front of the vehicle it will have a power terminal under the hood "usually around the inner part of the right front fender or the Intake manifold area" it may and may not have a red cover on top of it, but it will certainly have " + " mark flip the cover up there you will see the metal nut where you can hook up the jump cables to then for the negative you can hook it up to the body best place is the bare metal structure of the engine, "or if you are not sure hook up the jump cables straight to the battery at the trunk"...

Answer 3

You might be asking this question with because you either want to offer or receive a jump start.

For both cases, the positive terminal is located in the engine compartment, on the passenger side (LHD cars); you'll see a black plastic cover with a "+" on it, open it, you'll see a sturdy nut attaced to a thick cable. This is the positive.

For the negative, a convenient place would be the engine itself. You'll see a metal "eyelet" on the engine (probably used for winching the engine out).

The battery itself is located in the trunk on the passenger side, underneath the black plastic tray in the corner.
