Most likely a 3.73 open differential.
However the S3.73 lsd differential was an optional in the 325i. Check under your car to see it. There is a tag in the differential that should say 3.73 or S3.73. The S means LSD.Erick Mahle | FullOpp Drift | YouTube

Should be a 3.73:1 Open differential.
How many lines you leave doesnt mean shit. Crawl under your car, clean off the tag on the diff, and read what it says. If the numbers on the tag start with a S then its LSD.Tenured Automotive Service Professional - Avid BMW Enthusiast
