hi,
i have a nice audi b4 quattro. when i press the buton to angage rear differential the abs light apears on my dash and a green light apears on the buuton . how can i find out if the differential works? please help me

 

ABS goes off when you lock the dif -- the green light tells you it is activated.

I believe it will automatically unlock at 15 MPH or something like that.
