This would be my first post, so I'm not sure if this is the right place. But I own a 1992 325is, and I've been noticing that there is this rattling going on underneath my car. The cause of the problem has been up in the air with me. The guy that I bought it from cracked the oil pan, fixed it and put a steel bar underneath it. I'm not sure if it's my shocks/springs or that bar that is rattling. Anyone else have or has had this problem?
