Need assistance. First post. First BMW. self level warning light came on intermittently a week ago. Now stays on. The green toggle light stayed lit until today. I checked all fuses (right rear storage compartment & glove box). All seem good. I don't know where or if there's a relay to test. I've read multiple forums and got ideas what to look for. The nose dropped but not the rear. All are even (no right/left fail). What I would like to do is jump the compressor but don't know what wires to connect to. I don't want to fark anything up. Can somebody assist me with what to keep looking for before I have to send it to the "money mongers"?
