The car is a 99-E300TD. The driver side fog light is not working.
I removed the old bulb by opening the hinged door of the lower panel - under the car. The bulb filament was broken.
Safety issue - the bulb is pressurized so if it is dropped could brake and pieces of it may get into the eyes. Wear safety glasses and gloves.
I bought a new H1 bulb. By the way the part number 000000 000268 of the original bulb (Philips 12258) has been replaced with part number 000000 000375 (Osram 641508).
I placed the new bulb in its location. Then I turn the fog light on. The driver side is still not working.

I took a look at the fuse box - located under the hood, on driver side. After I open it I found a fuse designation sheet (Part number 210 545 19 00) dated July 31, 1998. None of the functions listed on Side 1 or Side 2 is for fog lights. The entire E-Class (300, 320, 430 and 55) has fog lights.

Now my question: Could be a typo on the fuse designation sheet? or the fog lights are called something else?

I checked the fuse no. 9 (for fog light) - driver side in the IP (instrument panel). It is OK. The bulb (H1 for fog lamps) is brand new. Using a voltage tester I found out that there is no voltage at the end of the wire going to the driver side fog lamp. The pasager side fog lamp works.

Do you have any advice for me?

You might want to check the wire again. You could have damage the wire "internally" during the removal of the old bulb. Try wiggle the wire with the foglight on.

Good Luck
