Hi

I have a RHD ( UK based) 2006 E320 CDI sport with what I assume are factory-fit HID Headlamps. DS1 35w Phillips Bulb and Ballasts

The drivers side dipped headlamp is off permanently. I have swapped the bulb and base unit ( I believe this is referred to as the ballast) with the working side but that still doesnt work so I have eliminated the bulb and base unit. I have tried locating the fuse but it doesnt show on the MB Fuse diagram. I then assumed the fuse would be located in the engine compartment fuse box ( as MB do not show that in their fuse chart) but all those fuses are Ok.

Also the ballast unit on the non-working side does not locate within the headlamp unit with a solid twist and click as with the other side

Can anyone help ?. Just so you know I am not that technical

Thanks in advance
