Great To Be Here and question right away

I have recently bought a 2002 325i and being a hands on person will need to know as much as possible about my baby.

Can anyone say if there is a pressure regulator valve for the differential?

I have never heard of anything like that.

I notice that there is some oil on the cross member below the point where the drive shaft is attached to the differential. However, I did not see a particular place where it was coming from and since I have cleaned it there is no obvious leaking point.

Some older rear wheel drive vehicles had a pressure regulator valve that would activate to reduce pressure inside the differential especially during jack rabbit starts. Sometimes they got clogged up and did not relieve the pressure thus causing some oil to escape from the differential.

I think you're probably looking for a normal leak.
