Ultimate Family Hauler - ML 350 Build Thread
Recently 1 of the brake light bulb burnt out. I attempted to switch the led version, but failed. None of the canbus led work, regardless the price and brand
Went to the dealership and got a new pair of oem bulbs
This is the sample of led i got from amazon. Almost $40, still don't work
The oem bulbs looks pretty high quality
This is the part number for the oem bulbs
This is the video i used to change the light bulbs. Super easy, 5 mins job

My coolant was due at 240 000, but so busy lately with work, so didn't get a chance to change it till 250 000 km
This is the coolant i got from my local Mercedes dealer. Not bad at all in terms of price, only $30 CAD. And it a 50/50 mix, that mean you can get 8L out of it
Make sure you use the distilled water. Only $2 from no frill.
I didn't have the proper size of tube to direct the coolant. I made a little bit of mess, but was able to clean it up after with brake cleaner. Next time if i do it, i will get a tube to direct the coolant, rather than make a mess. I believe it a 10mm tube to plug in the brain plug. Also took forever to drain out the coolant
You will need 1 of this tool to loose the drain plug. There are only so much room when it comes to loose the coolant drain plug, a small version of this tool will probably work amazing
Drained out almost 7L of old coolant
I gave the coolant housing a good clean
I topped up the coolant. Took it out for a spin, wait till it cool down, and topped out again. Took me 3 tires before i can put back 7L of fluid in the system. Don't forget to turn on the heat while bleeding the air out from the system
This is the video i used to help me flush the coolant. It helped me out a lot. Without this video, i don't think my coolant flush will be that smooth. I can see why dealership will charge like $200 to change the coolant since it takes time to drain. The shop has the vacuum tool, which can save them some time to refill the coolant. Overall, this is a easy DIY for weekend warrior
Did some repair on my ML
It turns out great
6 coats of plastic dip and 3 coats of glossifier.
I am planning to add a coat of "dip coat", apply 2 coats of ceramic coats after the plastic dip is fully dry. There were a lot of scratches on the chrome bumper protector. I don't know why Mercedes did that, but the chrome looked horrible after it got age and the scratches are so noticeable. Now it looks a lot better.
I had some paint chips on my lower rear bumper. Because of the exhaust location, I cannot keep this area clean. Special I did the DPF delete, I can never keep up with the soot.
My kid used a shopping cart to hit my car

Not as bad on the other side, still a lot of paint chips....
This is what it looks like after the paint repair. Again, 6 coats of plastic dip and 3 coats of glossifier
I also sprayed outside of my trailer hitch to cover up some surface rust spot. I know it not forever repair, but at least it looks clean now.
I do think the plastic dip looks pretty good.
This is the final outcome. So far so good
Matched my black emblem.
So I finally decided to mount the block heater core plug in on the bumper
In order to mount the block heater on the bumper, first you have to remove the inner wheel liner on the passenger side. Once you removed the wheel liner, you will be able to access with the DRL panel , which is pain in the *** to remove. I tried with the trim removal tool, no luck. I was able to get it off with a long flat head screw driver. There are also one clip on the side on the panel, make sure you remove it before you attempt to remove the panel.
Once you removed the panel, then you can disassemble the chrome trim and the DRL. Start drilling the hole
Make sure you measure it few times before you start drilling
Test it and see if you can open the cap freely
, and the secure connection
Now test fit and see how it looks before you reassemble everything back
This is what it looks like after the panel got secured. I have to cut out one of the bumper clip in order to reassemble the drl panel
Before I reassemble everything, I decided to plastic dip everything before I put everything back. Once again, 6 coats of plastic dip and 3 coats of glossifier
Alberta rock chip hit my DRL :S I was going to order a new set from Amazon, but decided to keep using it until it burn out. I polished it and it turned out ok

This is the final product after I ceramic coated the black DRL panel
This is where the block heater plugged into. It located in the front of the engine bay on the passenger side
This is where I connect my ground
This is the final product. looks super clean

And the other side

I hidden the DRL wire on top of the front grill
This is the picture, I used some 3M tape
I probably can do a better job, but no one can see it. And I may replace my front grill to full black, so still have another chance to redo the wire

This is the connection for the DRL. I was worry about the moisture will get into the connection, so i wrapped up with the electrical tape
The DRL connection and the Block heater connection
It looks clean after the install
Here is the night photo. I know the led light and the DRL looks different colour on the picture, but in real person, it looks the same
Got another set of rims from Tire Zone. This set of rims mounted with Winter Tire. Blizzard DMV2
I ceramic coated my rims twice. Hopefully that can help it to keep clean
Can't wait to try it out on the snow
It's great that these panzer tanks have a lot of plastic underneath to protect the underside, but I am uncertain on how the body will fare.

Even the unit is small, it blows heat like crazy.
Here is his business info.
No more freezing while changing oil in winter time

This weekend I will work on the rear and front deff and also try to change the transmission and transfer case fluid. If I run into any issue I will let you know.

Thanks
Thanks




I also have a lighted star that I need to install. Do you have instructions on how to complete the installation?
Thank you in advance.
Chris
