open

Not necessarily. My '90 325i was automatic with all base options and had a 4.10 LSD. Check the tag on the diff.

Check the tag. It's most likely an open, as the LSD was a rare option on the i.

If the tag isn't there for some odd reason, the only way to tell is to remove the diff and look at it's internals. If there's an X-axis inside it's an LSD, if there's just a horizontal axis it's not.

Or, if the tag is there, I believe S stands for LSD.

Wrong.

Jack the back of the car up and put the transmission in neutral. Turn one of the tires. If the other spins in an opposite directions, it is an open diff. If they spin in the same direction , it is an lsd.
Lsd's have a "S" prefix tag if it one is present.
