This absolutely fixed my problem! My alternator shorted out and the fuse in the wiring harness from the alternator to the starter blew. I believe this problem also caused the the Rear Sam to short circuit. Because after I fixed the draining battery because of the alternator short, my tail lights would not light up, blower fax, dynamic seat control and my rear shade would not work. After going to the junkyard and getting a Rear Sam for $20, replaced my old Rear Sam and whalla! All now working because of Car D. Ologist! Thank you sir :) I am not a mechanic either but I had the wiring schematic to make sure I was replacing the right part. The Rear Sam powered the tail lights.

Awesome video! I just bought a 06 E320 CDI myself (idential to yours with 172,000 miles).I'm learning about my CDI discovering your channel! I now have owned every MB diesel model from 1975 to my current 06!

Thank You Soooo.. Much for this video !!! after Watching it i noticed my 2006 R500 had the same issues. I was going to take it to a mechanic but after watching i decided to go to pick-a-part and see if i could find the SAM and try to replace it. They didn't the exact match to my car so decided to pull the SAM of a r350 instead. I took it home installed it and wallah !Everything came back to life!!! Thank you again!!!

Just bought my used 2006 md e320 cdi with 207412 miles. Loads of issues but I am learning from your videos. Thanks so much.

This was a cliffhanger! Congratulations on having the courage to attempt this repair as well as persevering through all the unknowns without giving up! I have this same W211 E320 CDI and recently had sudden problems as the result of a trip through an automated touchles car wash. As I drove away it became clear that the high-powered water jets had reached a bit too far into the car and gotten “something” wet that needed to be dry. The ABS and ESP, also BRAKE and check engine lights have persisted despite a skilled mechanic with a powerful ADB scanning tool resetting. Going back tomorrow for another scan and fingers are crossed it’ll take this time. But I’ve researched and become aware that the W211 series has a known issue with car wash water intrusion, so that’s a thing! Thank you again for the exciting and dramatic video!

Did you ever had the issue fixed? What was the problem?

This is a great video that shows determination and love for your W211. A few years ago I noticed humidity in that area and sprayed it with electrical wiring oil that disperses water. At 258,000 miles I do not have the problem. However, you have inspired me to take the trunk apart and spray it again. These cars are tanks and once you take care of the Gremlins, the car will run forever. Enjoy unto another 270K miles.

Thanks for making the effort to make this video! As everyone knows when these things happen, mechanics out there may or may not know the solution but here you have your issues solved for less than 20 bucks. I have a E240 W211 myself if this does happen to me or my friend's vehicles one day, we sure know the solution to it.

Well done, Strong work! Prior to watching your video, I wouldn't have believed Rear SAM is swappable w/o SCN coding replacement unit to your specific vehicle although I've read in MB-world forums that this has been done before on W164 chassis. The W164 is notorious for water leaks around taillight pocket seals that eventually ruin Rear SAM in those if not caught in time.

Great opener isn't that us all. Your videos have helped me greatly, my Eclass is solid they sell for nothing that's why I'm keeping mine it's worth so much more than its worth if you get me. One big problem I did find was the underbody brake pipes here in Ireland we use crazy amounts of salt in winter the pipes were fubar only took me 3 months and 125ft of cunnifer. Keep up the good work glad to see your Eclass is still rocking.

Great video. And congratulations on a well executed repair! I have experienced some extreme water intrusion on my 2003 w211. The whole trunk filled with water. If you have a sunroof, the drains may be clogged, or the sunroof seal worn. I have also seen water come from the ventilation things in the wall in the trunk. I hope this may help someone prevent catastrophe.

There is only 2 bolts holding it in place, but when I removed them and tryed removing The EGR valve, it would'nt budge. Do you have any thoughts on how to remove an EGR vavle please?. Thanks for the great videos!

Excellent !

Hello Car Dognostic, can you please tell me which website you used for the parts number comparisons? Thanks much! My door function and trunk latch failed on a 2004 e320 4matic wagon, but everything else is fine.

My problem same with yours.. but what im doing is.. patching all water leakage and unplug battery terminal. After done patching all the holes..plug back battery terminal with the same rear SAM.. its worked back like nothing happen. Thats mean.. ur sam not broken. Its just going haywire because of moist or water.. after sam dry.. it will work like normal again

I thumbed up before watching the video!

Amazing

I wonder if the problem I have with the radio dead buttons can be solve by doing the same thing? Great Sunday project!! Good Job !!

One might add that the disassembly of the trunk liner will allow one to REPLACE THE REAR LIGHT CARRIERS! So if a light bulb is out in the rear light YOU CANNOT REPLACE INDIVIDUAL LIGHT BULBS!!!! So ..at about 100 bucks a pop, if one light bulb goes bad, you get to replace the ENTIRE carrier, after disassembly of the trunk liner, as shown here. ALL the light bulbs (rear light, brake lights, reverse lights and etc) all mounted in one cluster that you need to replace. Naturally one tries to replace just one bulb, trust me ..I tried. Not the way to go. Just find the least expensive source for that part on the internet and one a light bulb goes bad, just replace both carriers. As for replacing the SAM The little celebration dance is TOTALLY RIGHT! 20 bucks vs dealer work to the tune of a couple thousand! YES! (I got the same car, same attitude), Mr. Car D. Ologist has in the past given me the best pointers!!!!! THANK YOU Mr. Car.D. Ologist!!!!!

Only question before doing everything. Did you try just unplugging the battery wait about 10min and plug it again to see if everything went back to normal? (Unplugging both batteries)

Only problem im having with my w211 2005 E500 is the rear sunshade is no longer working is there a fuse location for it in the rear sam?

Is there a way I can show you the file with the pictures please, and then take it from there? Eagerly awaiting your response. Thanks.

Hi! Im gonna replace mine on the w211. One big question though.. Did you replace with a brand new one or a used one? Because a new here cost 900 euros and a used one between 80-200 euros

Friendly neighborhood junk yard........that's 'only' because "you no speak Spanish" ha ha. Benoist Farms Rd. WPB (been there done that) I have a MB identical to yours with 190,000 miles on the clock. Hope I never have this problem. Thanks for the great information and the heads up!

Does the module unit number have to be exactly the same for both?

👏👏👏👏👏👏👏👏

After rain my e500 beast seems do not like extra water the cluster shuts down I believe it's some safety electrical trigger the event of dead cluster what I do to fix the problem a hard re set on the battery in the trunk remove the negative pole for a few seconds and re connect my cluster was fully functional again .

I got exactly the same constelation of problems with my e240 1999 though i cant get the trunk open in any way (The key doesnt turn) . I took the car to a locksmith hoping he can open the trunk. And i will follow almost the same stops you did to try tô got it fixed. My local mercedes dealer doesnt even accept the car because its ver old. So, i dont have any other options. Wish me Luck!

Does this rear sam steer the navigation cd unit in trunk?

What about w211 2005 E55 AMG will this work? my key fob doesn't work either And Also getting voltage battery ans SRS see dealer, got 2 new batteries new alternator new voltage regulator and still battery dies overnight , hoping this would be my problem to 🤞

The best part of your repair is when you actually fix the cause: water intrusion!! Most would ppl have only replaced the old SAM... The legendary rear SAM'S are excellent trouble sources both electrical and half-baked CAN software integration. I have a W212 and confirm they are SCN coded. Some online services provide repairs to bypass needing re-coding. NUGGET: Bösch CAN busses practically work better with NO Faults. For some obscure reason the more faulty CAN modules are present, the more busy buses will be with greater latency delays... that in the end even the engine won't work as well. Crazy door modules or camera are on separate CAN but affect car through CAN "Gateway Module" that routes messages between the 5 CANs. Most stable modules are engine + transmission while other unreliable peripherals modules are reliable revenu streams by designed! 👍
