Where is the 1989 BMW 325i’s OBD port location?
My grandfather’s been driving the same car for decades, and now he’s talking about getting rid of it because the check engine light came on. I’m pretty sure I can fix it, if I can just find out what the issue is though. Can you tell me where the OBD port is on a 1989 BMW 325i, so I can help my grandpa out?
