Mercedes ML 2006 rear SAM repair. No tail lights, no remote etc... Fault finding and repair. 

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!

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 👍🏻

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.

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

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!

It is great that you could save the PCB of the rear SAM. It would have been nice to see the actual repair steps, though. It is clear what to do in principle, but it is better to see the actual work (e.g., regarding the amount of pressure to use, etc.).

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!

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

Pretty amazing finding that SAM problem so quickly. Love yur Autel scanner too. That might b my next one.

This is class because its almost identical to the ml280fault codes im seeing myself on a customers car.

WOW!!! Awesome job on cleaning the rear SAM pc board.

Great vid, very interesting and i must add "eye opener" in my case. I have w219 and my problem is dynamic seats, sometimes work other time doesn't . After i watched your vid i realised that my air compressor (in trunk) doesn't get power .... I will take out rear SAM and see can i fix it .. Ones again thank you for sharing knowledge ..

you're an Ace, specially with removing all those R-SAM connectors without busting any multilayer PCB vias !!!

Saved me a fortune luckily not as bad as that but a tooth brush with some alcohol glass wipes worked a treat. Just need to get new rear light seals and fix to the car not the light unit as that's the cause of the water ingress

Me sirvió de mucho! he reparado la tarjeta del SAM de mi ML350 gracias a este vídeo. Te felicito.

Bravissimo! Devo fare la stessa cosa mi sa. Grazie :)

Fair play the plugs removed from Sam was a big enough job but repair not replace top marks again 👍👍👍👍

este es el mejor video de esta clase de problema gracias this is the best video about that kind the problem tks.

Wow that looks bad, I had to replace five IC's on my Mercedes c230 fuse box located in the trunk, one IC was the VND830 & the other four were VND810 very easy to install.

Nice job, I have a 09 gl450 no turn signal light, no wipers and fan it's on high. I can't comunnicat with any module. I have the same scanner

Wat a video thks alot i got e55 w211 and my leftside headlights nd foglamp not wrking it shows faulty display im gona check the rear sam

Great job, again a lot of money saved for the customer.

As always brilliant video! Like me you are not a mechanic who likes to throw new parts at a problem. Very well done at attacking the board problem head on lol it did looked very bad.

Hi where in UK are you? I have a rear sam issue and would like to bring the 2006 model of this car to you. You did a good presentation.

very nice video..... I think water has entered in SAM, but luckyly there isn't any short circuit?

Clever Guy ! Thanks , I had similar problem on a Merc Van.

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!!

This is really helpful! The best thorough video on RU-vid/internet! Good job mate

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?

@LM Auto Repair: OMG sooo helpful I just subscribed😊 how did you remove the plates you didn’t show that I’m going to do that because I have no tail lights at all didn’t know what was wrong WOW thanks a bunch 💃🏽💃🏽💃🏽

Hello, I have Mercedes x164 and I once in a while I get no sound from the amp once it rains. Guessing this has to do with the rear sam. I have Mercedes star computer.

Hi my friend my ml 280 ewreting is working bu only back right nothing working possibilit sam module or something

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

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

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.

Great video on a known problem of the w164 ML. What did you use to seal the taillight seals? Thank you.

Rear Sam ctrl oll the electric and star windows everything.?

you are the man.you are the man...period

Thank you for your video! How did you remove the black plug housing? Do you have to desolder them? Or can you just pull them out? Thanks!

Hello I have ml 2008 320 after battery dead my rear lights are working, my remote work only if I near to driver door and my fuel gauge not work , interior light not work if I open door... If I open door nothing apper on display, my car locking automatically even is front door opened is this Sam module fault

My tail lights dont work only right side blinker works but some mechanic somehow gets them to work and it does it again what can i do to fix it?? Please help

You are really good at your work. Top marks 👍

Why isnt mercedes being held accountable for this this happens so much with there models

Great video thanks but my problem is trying to get it out if I could get the fuse box out of the way it might be easier, but can't get the block connectors off the back, so struggling to get the Sam modal out at the min, any help would be appreciated thank you👍

Thank you very much for sharing your experience and knowledge! A great help 👍👍👍👍👍😉

I am in the middle of this process and cannot figure out how to get the plugs off the circuit board so I can clean underneath. Can you help me out? Unfortunately, that portion is missing from your video. Thanks in advance.

How can I do the facelift for Mercedes-Benz cls 500 2006 rear taillights with 2009 led lights?

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, I tried same but didnt help me. It was smaller but it looks one black part it completely burned. What is approx price of new part in UK?

Good video, honest commentary and insightful. Thanks.

Thanks just increased my knowledge a whole lot keep up the good work.

Thanks your videos mate. I've go right now the same problem but I have cleaned the rear sam but still the same problem, I think is damaged and looking for one to replace it but is so expensive. Any option to fix it?? If you know some one doing this job ?? Thank you for your help.

Brilliant top bollocks it's simple when you've got the gear. Can't get my c/l working all my lights at back are working I'm scratching my head ?

hello , thank you for you help , really appreciate it . do you have any experience with W211 Edc 16C2 , i have two cases that , the clients car after bad battery did not start or crank , after replacing with new on the problem was resolved . i have opened them to check for any blown transistors , but looks good. may be there is dump problem and can it be resolved ? thanks again

Thanks for the great video.. You saved me lots of money!

Thank you for the great job,I was wondering if you could tell me how did you remove the plastic connectors.

LM hope all is well , so I unplugged and checked rear Sam did not really look bad or water logged i reinststalled ran codes 20 for rear Sam I cleared and rechecked only 3 came back 90BE ,90BA ,90B6 CODE READS 90BE, THE LINE FROM COMPONET N10/8 REAR SAM CONTROL UNIT (PIN F.12) TO COMPONET A72 REAR DOOR LOCK UNIT PIN 1.10 HAD A OPEN CIRCUIT OR SHIRT TO GROUND. I FOUND PIN F.12 .BUT WHAT IS OR WHERE IS PIN 1.10 ITS THREE CODES LIKE THIS F. 11 TO PIN 1.3 AND F. 13 TO PIN 1.3 .. I CAN FIND THE F PINS BUT WHERE ARE THE NUMBER PINS 🙏🏽Your help would be greatly appreciated.. thanks again

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.

Good Job! 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.

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?

Hi thank you for this video but I am ask do ammublaizer fined in sam with thanks

Excellent video .. I have 2006 ml500 I'm havinf no power to the rear hatch lock and fuel filler door would they happen to be on the same fuse or can bus link

Job well done and Great video! Really enjoy watching it. May I ask what Autel Maxisys you are using? also if you do replace a bad rear SAM with a used one do you need to have it programmed by a Mercedes Dealer? Thanks in advance,Keep up the good work.

Keep up the good work buddy..Autel is pretty impressive

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.

Like your video 👍 i have a 03 clk500 w209 having problems with my rear taillights as well i believe it's the rear sam control if i remove it will i have to reprogram it? Is this true

Hello, good job guys. thank you for this video. I would like to ask you a question about the hotel maxisys: please give me a link because I'm looking to bay a good diagnostic system, thank you very match Omar

Hi I mean in my question is it ammublaizer found inside the s a m and thanks

I fitted a new rear sam unit today. The fuel guage wasn't working at all.

Tenho uma ML350 e o painel não acende mais, será que pode ser o módulo sam? Nenhuma oficina conseguiu arrumar

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?

Hello, How did you remove the pins from the electronic board?

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

caused by the rear light seal perishing letting water get into the rear sam, so you need to put sealant around the seal..........

i got a 2008 ml350 v6 engine. when my SRS LIGHTS come on my wiper seat adjust signal light and trunk wont open can you tell me how to find the problem????????? please

Do you have to clean under the plugs ? I mean when its just the corner of the board corroded thats why i dont looked under the plugs because there can't be water damage logically.

hi mate were in UK are you and on a 2007 if you get used sam if parts numbers are the same is it plug and pay

This video helped me out massively, I’ve had the same issue on my x164 witch I’ve now sorted👍🏻 Many Thanks for taking the time to post this video ❤️

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?

Thanks for the great video. I have the same problem after the battery went flat. I have no tail lights, remote inop, fuel gauge zero window wiper inop no signal lights. Now the shop asked me to replace the SAM. Do you need to disconnect the battery before removing for cleaning? Thanks again

Great video, nice to see it's working again after spending so much time:)

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.

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.

With the sam issue the engine cranks over because mine is not cranking at all

Thank you teacher 😊😃

hi could you tell me wich pins on the sam ( named also n10/3) controls wipers on slk320 r170 ? problèm is wipers don’t want to stop when i turn them on (constantly running need to turn off ignition to stop them ) and culprit is sam as when i remove sam to swap with an other sam all work good i open the sam but is in very good condition with no corrosion at all so it is probably an invisible little scratch somewhere that is why i need to know wich pins are involved about control of wiper in order to check very carrefully

Thanks for the video ! I have the same problem, how do you remove the connectors from the board ?

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

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!

Great job. Just subscribed. I have an issue with my near side rear number plate bulb not working on my SLK 350. I have replaced the bulb but still not working. I am guessing it's a problem with the rear SAM. Do you have a website? Thanks. Jon.

Great Video! Thank you for sharing. I had also the problem with a corroded rear SAM. After deep cleaning it started working but i can hear SAM humming. I am not sure whether that is ok or will SAM die soon?

when you connect back the rear Sam does connector H connect to a cable because I don’t fine the connector??

Hii..m working on mercedes e250...its not starting...the rear sam module has water intrusion nd damage...can this no start be due to faulty rear sam??? also the ECM has a fault code CAN bus off...can this be due to faulty rear sam???? plzzzz advice...thank you

My ml does not have the power light gate so it doesn't have tail gate module it does have electric lock actuator.

I have 2009 ml350 gas gauge stuck on full I replace fuel sending unit and no luck

How can i get in touch with you i have the aame problem 2001 ml430

Thank you for this. Can't believe that board was savable. Did you apply conformal coating afterwards?

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.

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 ? Do that need to reprogram when you remove ?

If you had to replace the module, how would you code a new one?
