I've had a search through and haven't found quite the symptoms I'm experiencing. Apologies if I have overlooked something.
Car: BMW E39 520i Saloon
I've had an intermittent issue which has now become more prevalent with my reverse lights not working. When the issue is present, and I put the vehicle in reverse, the rear fog light indicator on the dash will turn on and the reverse light will fail to turn on. I've also noted that when turning on position or dipped headlights, the rear fog indicator on the dash turns on also (the read fog lights do not turn on in either of these circumstances).
I've changed the lightbulbs (one of my rear position lights was burnt out and has been replaced now also), and I've replaced the fuse per the diagram in the fuse box. I understand the next thing may be the switch in the bottom of the gear box, is that right? Aside from that, is there anything that could be causing this? In particular, the fog light indicator turning on puzzles the smeg out of me.
Any help greatly appreciated.
