Hi
This Mercedes ML 6.3 AMG 2006, came to me with a few issues... tail lights and remote not working, boot not opening etc...
Was easy to suspect of a problem with the rear SAM, but much more difficult to repair it....
Follow me on this video to see what was wrong and how I have repaired it.

Thanks for this, I just rescued my SAM with the help of this video, tail lights stayed on after pressing the brake pads, scan showed 20 error codes, so I pulled the SAM and it was full of water, the previous owner had wrapped the SAM with a plastic bag which made it even worse as the bag was filled with water. Water ingress was from the vent at the rear right side facing the bumper (apparently a known and recall issue), So right now I have a temp fix, had to pierce a hole in a rubber plug below the SAM unit, till I have time to drop the bumper and fix it properly, so should have no water in there for now as the water drains out just above the rear muffler to the ground, so will sort that out to avoid rust issues.........thanks again LM Auto Repairs!

That is great!
Thank you for the feedback!
thank you for sharing your detailed investigation on water source... many chassis models probably affected by faulty vents...
Can you email me at aoel2006@aol.com. Want to hear how you did this rear sam fix. Kunle here too
A plastic bag can literally be a death sentence for your SAM especially after too much time has passed. It's incredible what some people try without completely thinking things through. Good luck in the future.
Great job on the Mercedes ML. I had the same issu on a coustomer car not along time ago. I clean the board whit tornado gun. And after cleaning whit the gun,I did use a heat gun too get it dry. Board was good as new. Everything nice and clean. I think it took me around 15 min to clean the board. Keep up the good work you are doing😁I`am a mechanic my self from Norway🇳🇴End i have watch many of your video`s. And you have give me more great idea`s too work on car. I`m impressed 👍🏻
😊
Thank you very much for the feedback!
Really appreciated!
Also, thank you for follow my channel and watching my video!

What’s a tornado gun?
Ah hahh anothee great easy fix. I try to explain this to so many people. But they dont get it. Guess us mercedes builders are a different breed
🤗🤣🤣
Possibly...
Thank you for watching and for your comment!
After cleaning the rear SAM do you coat it with any dielectric grease or anything to prevent future corrosion ? Wish we could all find a man like this to take the time and initiative to actually repair a car rather than just push us into buying an expensive replacement. Well done sir!
Hi
I use a a kind of a varnish to seal the board...
I used it in this one, and many others... just forgot to mention...😊
Conformal Coating can be used
Thank you for the description!
I just did the same repair on a W164 and it worked perfectly. Your video saved me a lot of time and money.
Keep up the good work and thanks again!

That's great!
Thank you for watching and for the feedback!
The owner of the car just told me that he called Mercedes and asked about their price for the repair, just out of curiosity. They asked for the chassis number and called him back 30 min later. They would have charged 600 EUR for a new SAM, plus 300 EUR for the exchange, plus taxes.
I do not want to bash Mercedes here. I understand that they have to charge as high as they do. I just hope they spend enough of that money in the R+D department and not give it to share holders only.
@@fil23873 I am having this exact issue with my 2006 ML350 and am so furious with mercedes right now. That is a terrible location for such an important piece of electronics.
@@Spacecraft_Repair The water comes in through the gaskets of the rear lights. You can buy a set of new modified gaskets from Mercedes for the rear lights (I don't recall if this was already mentioned in the video above, sorry).
Apparently this solved the issue with the rain water leaking into this part of the chassis. Part numbers are: A1648261691
and A1648261591.
@@fil23873 Thank you!
Pretty amazing finding that SAM problem so quickly. Love yur Autel scanner too. That might b my next one.
Hi Brent!
I might was lucky... lol
It is a nice scanner indeed...
Thank you for watching!
Did You cover both sides of this SAM PCB plate (same with front SAM) with poliurethane lack? Did You recover proper sealing of 2 blank caps rear left and right on top of D pillar (under outside plastic cover)? That causes this problem with humidity both sides in trunk under left and right panel lining and damages SAM because through this caps each ML has water leak to inside.
i had same problem on focus 2003, rear lights plus fob few lights on dash , i just taken out Control Module, and put heat gun to it now all works fine

Hi, I have a 2008 Mercedes R-350 4matic and I'm having problems with my tailgate. Opens with remote, door button & tailgate handle, but doesn't close from none of this options not even from tailgate button. When I pressed any of this doesn't do nothing at all, no noise, or anything to let me know that its sending the signal. It's like if its death. The only thing it does it's that the tailgate button light its on.
The last time My tailgate stopped working, I pressed the close tailgate button, but door only closed halfway, then it open by itself all the way (like if there was sensing something on the way), then I tried to close it again, and it will come back to open position, but not all the way. So I keep pressing it a couple of times, I pressed one time, then I hold the button to see if would open all the way, then I keep pressing it a couple of times.This happens like 3 times, then it stopped. What I don't get it's why opens, but doesn't close.
I checked the tailgate lift control unit module inside board but looks like new. Then I also checked the rear sam board and looks like new too.
Do you think I unprogrammed it, and now needs to be reprogram?
Can you please help me to troubleshoot. Thank you.
I would start by scan the car and look at some live data... see if the ecu is seeing the closing signal etc...
But...

@@nicksilverman3333
Don't waste time or money by throwing parts at it...
Scan the car, analyse live data etc... and go from there... otherwise it can become very expensive, very quickly, and with no results at all...
Hope it makes sense...

@@LMAutoRepairs The front SAM on my Mercedes Van was damaged due to my own fault - converting side marker lights , side lights , number plate lights and cab light to l.e.d.'s -
SAM unit permanently broke and I ended up sourcing a second hand one , so it was a lesson learnt regarding using l.e.d.'s !

How did you take off the pcb board inside the Sam? The little black clips keep it connected. Its frustrating...
@@explorinlearnindoing5462
Mine had a black plastic outer cover which I very gently prised the black clips back then lifted each one up slightly to stop then pinging back in place after I did a couple the cover sort of popped off. It was a bit off a pain
The PCB board is screwed to the metal part of the SAM frame with 8 small torque screws with a layer of thin plastic to stop the PCB touching the metal part.
Hope this helps
@@timthatcher6131 Thanks Tim!
It seems as mine is a bit different.
But I got the board out of the black cover. Mine was held by the huge electrical connectors which had clips aside. After pulling them back one by one over the complete board it immediately came off...
Now I am going to clean it....
Fingers crossed 😊👍
At 0.24 in this video you can see how the pcb board comes off th-cam.com/video/LK5ccQ_IG0c/w-d-xo.html

Great vid, but.... I whish you showed how to take off the pcb board from the black housing. Those little black clips keep them connected. I tried a lot. And the huge electric tower connectors?... how do you remove those?...
Thanks in advance!!
What about if i put the same one back in not a new one? Thank you for your time. I really appreciate you answering my question
That's what I have said...
If you just take it out, do whatever and put it back, will work just fine....
ASE CERT MASTER TECH! Tne module is complex and integrated, once damaged it best to just replace it, these fixes are temporary, and well fail again possibly damaging other components! No one has time for the back and forth thing, Life is too short, do it rite and be done with it!
For someone used to just replace part, your advice makes sense...
Let me let you know, that, this repair was done nearly 3 years ago, and still going...
I think the the "temporarily" term doesn't really apply here...
Also I do believe that always worth to try yo repair before replace... unless the damage is really bad...
Anyway, thank you for watching and for your comment!
Thank you for this.
Can't believe that board was savable. Did you apply conformal coating afterwards?
Yes I did...
I failed to mention it i think...

Nice repair, I bet it took a few hours to De-solder all them socket pins...

Hi, Thank you very much for this video. I've removed my rear SAM from a 2007 ML320CDI but have been unable to clean underneath the plastic towers. How did you remove them? I tried following the links in your description but they take you to an ebay page that says the item is sold out. If using a heat gun does that mean that they are melted in place with those black plastic pins that stick through the back of the board? If that is the case, how do you reattach once you've melted them off? What % alcohol did you use? I used CRC QD Electronics Cleaner and it's been less than perfect at removing everything.
Hi
As much as I try to keel updating the links as the sellers stop selling or the items became unavailable, is nearly impossible...😔
I have now updated all the links, all you need is in those links... plus a lot of patience....

It will be great if you upload a video in which you are replacing MAF (Mass Airflow Sensor) on Mercedes-Benz A160 98' w168. As you may know this sensor is soldered on ECU of the A class and it is pretty common issue on this model.

What is it with Mercedes? Every Mercedes ever made has a defect that causes the electronics to get wet and corrode whenever it rains. I've had a couple Mercedes and each one has had to have the electronics replaced at a cost of many thousands of dollars. All it take is a bit of rain and the water wicks into the circuit boards and causes damage. I suppose Mercedes never heard of silicon seal or waterproofing?

Hello again LM I'm in desperate need of your assistance.. I have not found the issue with my rear hatch power issue it's not funtioning . I just found out that the fog lights ambient temp sensor high beams I think the bulbs may be blown high high beams are not working I did however repair the fuel door switches complete system out to find that the connector wires were cut or torn I spliced back together that now works
Thanks for sharing a great video. I got 2008 E350, the fuel gauge shows empty all the time even the tank is full. I checked both sending sensors in the gas tank, both is good. Do you think it could be the rear SAM module problem? I already located the SAM module but have not remove it yet. I though I will get a replacement SAM first before I start taking it out.
There is a good possibility that is the rear sam... As is the rear sam that processes the fuel tank sensors signals...
Thank you for watching and for your comment!
I have the same problem w164. the fuel gauge shows full all the time. I did cleaned the sam all problem solved except fuel gauge, and front seats not working. Could you please give me the circuit board diagram for rear sam to identify which chips are responsible to be fixed.
By the way my seat belts tensions can't retract, is that related to the same problem.
thanks
Did you find the cause of the leak? I did the same thing to my GL several years back. Cleaned, reflowed, and reassembled. I did replace the taillight gasket at that time, but I did not see any signs of water intrusion. I am wondering if there is another source of water intrusion I have not found. I reached into the rear well where the sam is located, and it felt damp. I don't know where the water is coming from. I ended up sealing up the whole Sam unit into a gallon zip lock bag for peace of mind.

Hello my friend.. my ML 350 2010 wasn’t lock and unlocked and everything else was working perfect,, I removed the rear sam and had water inside. I cleaned with electronics cleaner and looks perfect., after I reinstalled now nothing is working, no reverse light no signal no liftgate no wipers etc. what you think ?

Most likely a dry solder somewhere...
Inspect it very carefully...
No reprogramming needed when you remove it etc...

thanks for the video, my GL450 left hand version with a remote that doesn´t work properly, just by IR and now i supposed that could be the rear SAM but i don´t have the scan tool that you have and the price of a new rear SAM is very high to verify with a new one if is that the problem or not, any comments about my situation?, thanks in advance
Hi
Check it visual... if there is water ingress, which is a common problem, then you might have your answer...
That said, a second hand Sam will work, it is just that will most likely need coding to the features of your car...

I fitted a new rear sam unit today. The fuel guage wasn't working at all.
@A L
I meant it wasn't working BEFORE I changed the SAM unit. Sorted it though.
Great video, thanks :) I'm trying to trace a trunk fault after replacing the battery, I have had some water ingress in the rear left wheel well (not much but it's happening) I can't spot any real corrosion, tailgate pump looks ok, rear sam not showing any signs of corrosion or water damage, fuse 40 is intact, popped to my local independent Mercedes workshop and STAR didn't show anything, they've asked me to take it back so they can trace whereabouts the water is coming from but suspect it's the rear light cluster and will go from there...... is there anything else I'm missing?
Not really... not in terms of what you explained... the water usually gets in through the light...
Some investigation should reveal where the issue with the boot...
Thank you for watching and for your comment!
Very informative video- thank you! you've saved me $$$$. I had the same symptoms, and when I opened up my ML rear sam it had some minor water damage ( two spots) which I've cleaned with 91 isopropyl alcohol and a tooth brush. Everything works as it should now, but I've noticed that the SAM motherboard made a buzzing sound (just right after it was connected) for couple seconds and then stopped and never reoccurred. Is that normal? Is it the capacitor gone bad? Thanks for any clarifications.
Matt Barr
Hi
It is a possibility... check also that all the soldering points are good... resolder just in case...but if has not done it again, I would not worry too much...
Thank you for watching and for your comment!
LM Auto Repairs Unfortunately, all the previous symptoms have came back; now, the SAM module is making a loud clicking/ buzzing sound and when that happens the alarm goes off. Weird stuff!
Any sdvice?
Matt Barr
Hi
Just reflow all the joints etc... check that all the lanes are good... and repair any damaged ones...
LM Auto Repairs Thanks, I picked up a used SAM from eBay- I'll probably have to code it. Do I have to disconnect the auxiliary battery too before connecting the new SAM unit?
Matt Barr
Not necessary... but advisable...
You most likely will need to get it coded to the car... unless you were lucky and that came from a car with the exactly same options as yours...

That said, if I checked it correctly, the fuel tank lock goes to rear sam plug G pins 34 and 35, for the rear hatch switch plug F pin 7... but for the lock, there is a separate module... I believe in the boot door itself... all plugged into plug F...
Hope that helps...
Mann thankyou 🙏about to go read it and check it out

Thank you for watching!
The tools I have a essentially a temperature controlled soldering iron, a hot air gun, and a desoldering station...
The desoldering station is definitely the most helpful for this job...
a strong heat gun
Hi,
I have a 2007 ML AMG 63.
Problem is the front headlights indicator or turn signal lamps is not working. All other turn signals on the car work. When I put the left turn signal the fog lamp in the bumber flashes but the turn signal in the headlamp is not. same with the right hand side.
error code is P1614, Control module has in internal error.
906F headlamp
906E left daytime running lamp short to ground
906D left daytime running lamp discontinuity in line
9019 left/right washer nozzle or feed line short circuit
9012 right turn signal E2 e5 lamp short circuit to ground
9011 left turn signal E1 e5 lamp short circuit to ground
9008 headlamp
900A left fog lamp faulty or lead open short circuit
9070 headlamp
These are all the error codes.
Now I know the right headlight is faulty.
code 9070,906F,9008, is the headlamp error codes.
Now what gets me is that sometime they work. then sometime left works only and sometime right.
AND all the other lights are working fine, even the fog lamps. when the turn signal works fine the fog lamps do not flash. they are off.
I tested the ground wires for continuity and seems fine. Checked all plugs and wires, cleaned them up.
I opened the front sam loacated under the driver seat next to battery, ( south Africa) and visually no problem.
Any advise please
In that case more than check the ground for continuity, load the circuit.... that should more definetly tell you if the ground is good or not...
Hope that helps.

@@LMAutoRepairs hi just an update. The front Sam was not the issue. But when we took a wire from the battery ground, wile everything was connected, and put it on the turn signal ground it started working. Took the wire off and it has not stopped working sins. All problems gone. Can you explain this. Like it was charged or something.

🤔
That's strange... it shows however that was a lack of ground... so if comes back you already know...
👍
@@LMAutoRepairs Hi. So the problem with the indicator front light only not working is back. fog lamp flashing but no indicator light. I have to then look for the ground that is damaged or, any advise
@@sv_endless6340
It sounds like a ground issue... check them and clean if necessary...
I have 2008 ml63 Mercedes, sometimes my key don't read, now I have no tailgate.. Tailgate does not go up and down anymore. I notice that the lights on the tailgate button has no lights.. Do you think it is the rear Sam?
Could be... get it inspected...
👍👍👍
Thank you for watching!
Can you tell how you got the circuit board out. Because I don't know how to basically take the board off. The board is exposed but I don't want you breaking.
Sorry... but I can't remember now... done this long time ago...
Have you opened the plastic box I suppose... usually is some tabs that release the pcb...
I know is not much if a help...
Thank you for watching!
Thanks for sharing! I'm around disassemble the rear Sam of my w203. There are any trick to remove those layers and finally reach the board? I'm afraid of cause a worse damage.
Hi
What layers are you referring to?
Thank you for watching and for your comment!
@@LMAutoRepairs in the side where are all silver connectors, there are at least 4 layers of plastic. That area is my best guess to find how to open the cover and reach the board.
I decided to buy another SAM but now, in half way, i want to see the proper way...hehe
I have this same issue going on right now. If we replace the motherboard do you have to have the vehicle reprogrammed to the new panel?
Hi
Most likely...
For the most part everything should work...
But depending on the options and features, might be stuff that will need coding to the specifics of your car...
