I have done a quite bit of upgrades for my car such as adding power seats (heated/memory), auto dimming mirror with L/R power folding outside mirrors, upgraded HID headlights, aftermarket headunit/amp/sub/speaker/rear view camera, and updated the windshield tank to the 7L tank. Now I got my sights on this 2002 model that just recently came to my local pick and pull. It has a front bumper with the headlight washer system and fog lights. Being as I am eager to keep adding stuff my car I am very interested in retrofitting that bumper to my car. Anyone experienced in doing this? I remember asking a while back on this forum about replacing the bumper and was told it required some modifications in order to adapt the "new to me" bumper on my car. I also know the dealer or a mechanic access to a C3 or higher is required to activate the fog lights. Your opinions and suggestions are appreciated!
Thanks!

What are you hopping to gain? You will get lame fog lights and headlight washer system which is a nuisance. They leak. I removed & threw away the washer systems on my 500 & both 55's.

you can retrofit the bumper and the foglights for sure to any ml...

for the "physical" attachment :
1. you just need to make sure you get the right brackets that the "sport / amg bumper" attaches to (I think these are the same brackets also used for the ml500 (but I could be wrong)... in either case... the part i am referring to is a metal part located behind the bumper cover (the "bumper" is actually the metal part attached to the chassis).... so the brackets look like this (in diagram below circled in blue) :


2603328
2603329


they should be attached directly below the mercedes grill (on the bumper itself via screws / bolts)

2. there should also be 2 end pieces that would be good to get (circled in red below):
2603330


hopefully the diagram will be of help to you.

for electronic connection of fogs:
obviously remove the connectors you see... the fogs are pretty useless... but I have done a mod...that should be revealed soon ;) ... and..wow... its a good one !

ps: if you were looking after the ml500 bumper... not the ml55 / amg bumper... it should be similar parts... (i will add the bumper removal doc for future ref)

The washers leak from the plunger. The nozzle is attached to the plunger. The motor pushes the water from the reservoir. The water goes into the "syringe" & pushes the plunger up. The plunger lifts the nozzle up & water squirts out from the nozzles. They leak from 2 places. The "syringe" because the plunger rubber gets old. Also from the nozzle because the plunger rubber get old. The plunger has 2 functions , lifting the nozzle & opening the way for the water to flow into the nozzle. So when the plunger seal/rubber inside the syringe gets old it starts to leak & the only solution is to replace the whole mechanism( they are sealed units).
LED bulb will be better, but don't forget the design of the fog lights are made for halogen bulbs. Having a aftermarket LED fogs will give you a much better result. I have changed the 55 fog lights with aftermarket LED ones. My fogs are stronger and brighter then my headlights...........
Plus , unless you have wipers on the headlight, squirting of water is not going to keep them clean.

Perhaps you would still indulge me on this project. I know the headlamp washers are pretty much useless but I am the type of person that enjoys doing projects for the sake of it. At this point this truck is pretty much a project car that I am currently working on as a hobby. If you or the others don't mind in assisting me on this I would really appreciate it. So on to this project..... As far as I know the truck dose not have the k5 relay and fuses in slot 5 (needed for the headlight washers) in the passenger side fuse panel. In fact I think there needs to be some kind of snap in bracket to accommodate the relay and fuses. I am not sure where I can find that. The next issue is of-course the wiring. I can't clearly see where the wires are located in order to tap into the K5 relay. Is it imbedded in the wire-harness bundle above the passenger fuse panel? The third issue is where the headlight washer pump wires/connector are located. Is it tucked under the driver side headlight assembly or imbedded in the windshield pump harness? So far I confirmed that the connector for the headlight washer switch is indeed present behind the left side trim by the steering wheel. So at least that's going well for me. Again thanks

While I wait for some parts to come in. How much should i expect the dealer to charge me to enable the front fogs with their super expensive scanner/coder tool? I remember some folks saying they paid 25-50 dollars and others paying up to 150.....

I am swapping out a pick apart front bumper with fog lights, for the current cracked bumper.

On the pick a part bumper the left fog has 2 short hoses that go from the reflector and plug in to the back black assembly.

The right is missing one hose but has a longer hose that’s about 2 feet long these horses look like window washer hoses. So my question is what are their function?

I just want to be sure I have everything that I need at the time of the swap.

If you are talking about the fog lamp assembly itself then those short hoses, I believe, are for ventilation. I think that's what you are talking about? The other hoses are for head light washer system which consist of two different hoses. One hose that connects to both headlight washer nozzles and one hose that connects to the headlamp washer pump. I hope that helps.

My daughter and I pulled the bumper cover off the ml last night. The lights on it are the same as the first photo I posted. My guess is two different types of vent systems?

I am not too sure but it does seem like it's for ventilation. The replacement fogs I just got are made by hella and they have the same small hose shown in your first pic.

So an update on my project:
Sourcing all these components has been a real pain in the butt but fortunately I was able to get most of the major parts from the wrecking yards. Some other parts I had to get off from ebay and FCP euro.
Currently what I have:
Non AMG front bumper with fog and headlamp wash holes but no park sensor (in very good shape!!!)
2 x hella made fog lamp assemblies
Left/right fog lamp trim pieces
Headlamp washer pump
2x washer base units nozzle heads
Fog lamp harness cable
Driver side headlamp washer switch with trim piece

Parts I am waiting to be delivered:
Passenger side Auxiliary fuse panel complete with K5 relay/fuse
L/R fog lamp/headlamp nozzle support brackets
headlamp washer caps (unpainted)
Headlamp washer hoses

Tomorrow I am going to repair the cracks and scratches on the bumper and then prime coat the bumper.
The other parts I am waiting for wont be here till mid October.....damn slow USPS shipping.

I will post pictures soon of the primed bumper. Base and clear coat will be done in mid October as well.
Will update you all soon.

Alright I successfully primed my bumper! Maybe in a week or 2 I will start painting on the base and clear coats. This is because my friend is currently repainting his hood on his Subaru forseter and we only have one makeshift painting booth to work in. Once he is done with his hood we can start finishing up my bumper. Until then I am still waiting on those other parts to complete this job. Will update you all soon!

Looks nice and smooth. I should of brought my bumper down to you, you could of painted both at the same time.

Regardless our pick a part bumper had a small crack in it. Not too bad but was kind of plus sign shape longer on the horizontal. Got this from you-tube. I sanded the back of it with 60 grit paper, cleaned with acetone, clamped it as tight as I could. Mixed up black JB Weld plastic bonder, spread a layer in side over the crack. Then set in a cut piece of fiberglass drywall tape, spreading more plastic bonder over the top.

Since it is mostly the flat area where the snap in grill is, I can sand it smooth fill and spot paint.

What is the finial color of yours?
