I've been under my car pulling on the thing that I believe has the old bulb in it. For some reason, it isn't coming out. Instead of taking out my frustration on the car, I went on here to ask for any tips/advice on how to take it out. Any help is appreciated. thanks!

i hope you have used the SEARCH feature as well as viewed the STICKY.

the bulb is held in with your typical wire spring stirrups. I can swap bulbs by
touch through the trap door. since you're not familiar with this, you may then
want to consider pulling the fog light assembly which is held by single bolt.
visualize the layout and you'll never have problems swapping out the bulb again.

I actually did use the search, and this was the first one I clicked on... homerun, thanks to Raymond... appreciate it.

It would have been annoying to actually use the search, only to find a thread where everyone beat a noob down and flamed them about using search and no actual help lol.

My right side fog lamp on my 1998 E320 died last night. The left one is fine. I went to the auto parts store and swapped out the dead one for a new one, following the above directions. I also applied some dielectric grease per the clerk's suggestion since he said my lamp blew because of water intrusion into the housing.

Now both the right and left lamps fail to light up...could I have shorted a fuse when I was installing the lamp? Could it be the dielectric grease causing a fault?

Any advice is appreciated!

Hi, Pod. Please click user cp and edit details to add your vehicle and location to your profile, it's often useful information when you're seeking assistance.

If you overapplied the grease, it certainly could have. It's conductive, so it may have shorted the circuit. The little "ears" on the connector are the ground, and there isn't much distance between them and the (+) of the bulb itself.

BTW, if YOU didn't see evidence of water intrusion, I wouldn't worry about it. Unless you're regularly driving through deep water, it's never going to get into that connection area, though the lens will fog up because it's not airtight as the gasket dries out.

The most common issue related to the W210 foglights is the substandard wiring MB used, which helps things overheat and the connector then melts into the bulb. Once that starts to happen, the clips weaken and bulb life shortens, it's a vicious cycle. The only solution then is to replace the clips; no amount of dielectric grease will help that. There are workarounds and replacement harness repair kits available.

But for the immediate issue, I'd disconnect both bulbs and then turn on the circuit and check for voltage at the connectors. I'm guessing you'll get none, then you have to see what blew.

Good luck.

I edited my details, thanks for the tip!

I'll double-check and clean the connector, I don't think I put much dielectric grease. But could a fuse have blown just from me changing the lamp?

Not just from changing the lamp. But it really wouldn't take much grease given the proximity of the connections, so the grease could have provided the conduit, and I suppose if the connector is melted enough that could short it as well.

These were what mine looked like when I removed them:




But once you disconnect them, turn them on at the light switch and use a VOM at the connectors to check for voltage. The center (female) plug on the connector is (+).

Check_Codes:

Didn't need a VOM, I checked the fuse and it was blown. I guess maybe it blew after the lamp died? Thank you so much for the information. Benzworld to the rescue!

For everyone's reference, on a 1998 E320, the fuse for the fog lights is in slot number 9 and is a 15A (blue) fuse. The panel is the trapezodial panel on the driver's side dash which is revealed by opening the door.

Oh, and yes, once you see the mechanism for the fog light release, it's easy.

A small thing, sure, but I love the way the fog lights look. It just didn't seem right with them off.

It should trigger the message... :confused:
Wow it is probably not dead? Is it possible for one to be turned on while the other is off? Up to date I don't exactly know how the two light signs under the light switch work. At times the green one lights on but the orange one has never been on. Any idea what they are suppose to do?

In europe may have different behavior of lights... but when you pull switch once, rear fog light is on and orange(?) light lit, pull further and also front lights are on and also green(?) light illuminated (can't remember which one was front/rear). Main lights need to be turned on (turned to most right position). If you miss orange light you could just have need new indication bulb under the switch.

Have you checked fuses, I can't remember for sure but there could be separate fuses for left/right fog light (at least left/right park light have fuses of their own...). And park lights can be turned on in either side only.


Still, you should have defective lap malfunction message on...

Raymond, I'm able to locate the single screw to remove the entire fog light assembly, but the assembly will not come out. It feels like there is still something holding this thing from coming out. Whats the secret?

ya know, it's been more than a couple of years that it's not clear to me now. in the
STICKY, you can download your own set of parts diagrams into your own PC. may
save you some time down the road.

below is page from that file which (still) isn't clear enough for me to conclude. it
could be a two fastener thing so now i'm second guessing what i posted last year
about it being single bolt. note that there are two bracket angles which almost
implies two bolts. or, are those two forward tabs something that hooks to the
subframe and then secured by single bolt? dunno now. ignore 98 which should be
the single bolt holding the light housing to the bracket.

another thing to do which is pretty easy is to drop the plastic engine undershield
which is the size of a cookie sheet fastened with something like 10, 8mm screws.
that might give you better visual angle to peer into the fog lamp area.

Halogen bulb needed for fog lamp. Can anyone help to give that spec. lamp I.D. ? I need to replace the drive side fog lamp, instead I fixed the bulb because the connection between the negative leg of the filament and the frame on the bulb was loosed. However, I do not know how long the repair will last. I like to stock one for next repair.

How can a halogen bulb cost $200, are you series ? OK I found the link and the price is quoted $20/2 bulbs. Yours is a typo. Thanks So the OEM is a 3200K color is that correct ?
