My 05 or 06 3510i PTO won稚 engage. It worked OK yesterday, and simply won稚 engage today. I致e somehow lost the cover for the fuse panel (thatç—´ in another thread), so I checked all of the fuses. Theyæ±*e all good. My experience with solenoid coils is that they usually start giving trouble first when they are hot, but I知 open to other experiences there. I haven稚 checked the switch yet, but I壇 be surprised if it went bad since yesterday. Any other thoughts?
