When I got the error message on the console that a lamp was out and discovered it was a fog light, I thought it was the bulb of course. Turns out there is another simple point of failure.

The fog light housing has a connector on the bottom that connects to the car's wiring harness. This connector is exposed to the elements and under the car I am sure it gets wet from splash. The wires enter the connector and are soldered to female pin-ends that mate to the male pins on the fog light housing. One of mine was corroded and there was no connectivity from the wire to the pin.

If your fog lamp goes out, you can unplug it and check for 12v on these 2 pins. If you need to replace it, you need to cut it off close and install a new connector.

For future searchers, you need:

1 connector MB p/n 002-545-99-26 $4.34
2 pins MB p/n 018-545-38-28 $4.40 each

Can be fixed with car on jack stand through the access panel under the fog light.

PITA though.

yeah, the fog light wiring is a weak point on W210s. good thing you noted and
took care of the problem now.

Same issue but I attempted to retrieve parts via Silver Star Mercedes in Thousand Oaks and they said no go. Also, tried to locate the P/N's listed in the thread and EPC (Mercedes online parts catalog) did not list them in either electrical equipment and instrument or electrical system headings. Can you please send a link for where I can order a set online?

Thank you in advance.

Thanks for the prompt reply Raymond. I'm still trying to hunt down the parts numbers you provided.

I'm under the impression that I need a socket, as in A0005400966.

While I cannot locate the ae1m part number, I did locate your recommendations in EPC. Just don't know how an H1 bulb will fit in what you've recommended.

Can't I simply purchase a pigtail terminated with the socket which fits into the foglamp housing, put shrink tubing at the splice and insert?

Those are correct wire repair numbers. They are only found in the service department wire tool kit, therefore not in the EPC for the parts department. They can be ordered, much like special tools.

oops, looks like i transposed something. let me try again....

Thanks DJ. Raymond...are you researching the pigtail? Or, are these parts going to fit into the existing socket which currently has the male end of an H-1 bulb stuck inside it?

i'm simply interpreting (and verifying) that these p/n are showing up in the
MB parts list, and their relative cost v dealer price. your dealer has the
option to jack up the price, natch.

as to whether they are the appropriate parts to resolve your situation, I will
defer to DJ and ae1 who have direct knowledge.

Thanks Raymond.

Those wiring repair kits are going to be both the male & female ends for MAP sensors and the like. I will look up the correct connecter PN tomorrow when I get to work. From my knowledge, neither of these will fix an H1 style connector. Let me take some pictures tomorrow to explain further...

Thank you for taking the time DJ. While I'm unsure how a wiring kit which isn't compatible with H1 bulbs will potentially fix my fog lamp socket, I still appreciate your efforts.

There has to be an aftermarket solution for replacing an OEM H1 fog lamp socket.

First, I apologise for the delay. I have pretty busy with work. From what I have found, the wiring goes from the socket to the main wiring harness. The pins that have been posted previously are the connectors to the socket, less the bushings. Now, from what I have gathered from some bodyshops that there are some other wiring repair kits. I just sold the following part numbers to another BS a few weeks ago:

000-540-23-05
000-540-45-05

Both of these are wiring repair kits that can be used to repair the inner portion of the foglamp. The only aftermarket item would be the spade connector to the wiring harnesses, of which can be sourced anywhere. I hope this helps.
