New to the 5 series world. Just purchased a 2014 Msport 535d and it's in immaculate shape other than the fogs not turning on. The switch on the dash lights up the icon on the dash, pulled and checked all fuses related to lighting according to the diagram in the trunk (glovebox and trunk checked) which wasn't easy in the glovebox. Chances are slim both are burnt out but I ordered two yellow replacements anyway. Any ideas ?

Plus if the bulbs were out wouldn't there be a notification in idrive ?

Potentially, if bumper cover was removed the Fog Lights were forgotten to be connected back. Check the connection before going and buying new bulbs.

Just a shot in the dark, you are aware that the fog lights will only come on when the headlights are on, correct?

Yes I had them on, auto and manual mode. I'm currently trying to pull them out. I pulled multiple fuses and visually checked them but I guess may need to put a voltmeter across them

Am I missing any fuses? Highlighted the ones I pulled and checked

Am I missing any relays inline? Pulled the lights (factory led) and no power to the plugs

Power for the foglamps comes directly from the FRM. If it was a fuse/supply issue you would have a whole load of items not working, not just the fog lamps.

My best bet would be on the connector for the harness under the drivers side headlamp being unplugged following a bumper removal.

So you were correct and that harness was unplugged, but now when plugged in, only one LED fog lamp works, and its the passenger side that turns on, nothing unplugged on the passenger side that i could find. I guess previous owner unplugged instead of fixing the broken drivers side fog? Not sure I want to pay $300 plus for a fog that hardly adds any light visible from the drivers seat.
