I subscribed and gave you a thumbs up.

My Benz won't start a few days ago.
I had it towed to a local shop.
After a day I talked to them.
They said they fixed the problem, and was a faulty fuse.
He said he found a engine misfiring when he took it for a test drive.
They wanted my authorization to continue working on it.
I said no, I will pick up my car this morning.
I do service on my car religiously, I change the oil less then every 5000 km or 3100 miles.
I have never ever had a chech engine light.
Now after 24 hours at their shop I get a "check engine light"?
When I got home, I parked it in my driveway and locked the car.
I always get a beep and flashing lights when Iock it.
Now I only get flashing lights, no beep.
When I call them to see how I can activate my beep, they said I need to bring the car to their shop and book another diagnostic appointment.
Are you kidding me?
So I end up with anther huge bill?
Unbelievable.
😭
And they wonder why many people don't trust mechanics..

That's actually NOT the Sam module! it's an integrated fusible link platform, the SAM is on the other side where there are fuses and relays on top and the electronics are situated underneath on a, motherboard.if you had a crash there would be a pyrotecnic high amperage fuse that would disengage the power from the battery in the event the vehicles fuel lines are ruptured or if any electrical loads get shorted to create a fire and create a safety hazard.

I feel you could’ve show more on the module take out and you could’ve showed on how to put the module back in of the new one that would’ve been very helpful

Thanks George You saved me a lot of money, I hadn't driven my car in over a year. Back on the road again. Yeah!!!

[seangallardo]

YOU ARE THE Thank you, i was able to repair my MB with your help! Tha'ts exactly what my issue was.

[suedoenim]

What about the metal part that broke? Do you have to replace that or the fuse that blew and broke it?

[TheSpeedfreak]

First of all I got to say you don't show where this module is so you know you could have uploaded that and edited it in. Second you not really saying what Mercedes models on model variants are covered. Really should least put something in the description.

Yo Blackguitarist. The proper way to jump start your MB is, you don't need to go anywhere near the battery! Instead you pop the hood, then you look up on the left hand side above the engine and on top the inner wing, back aways toward the windscreen in the area seperated from the engine bay by a rubber seal that snakes it way right across the car. (could be on opposite side on some models)
In that area you should find what looks like a small black plastic box with a flip cover on it about the size of match box though not quite the same dimensions. I looks like it may be hiding a relay or fuses. Often the cover is missing. If you flip the cover it should reveal a brass nut sticking up and nothing else, looks kind of odd. THIS IS POSITIVE LIVE FROM YOUR BATTERY SO BE CAREFUL!
So connect your leads to the battery of the car you're using as your jump, then connect your red positive lead to this brass nut and your black negative lead to somewhere on the engine casting, anywhere that you can get a good connection, I usually use the engine lifting eye. Always do it in this order not the negative first as connecting the positive second makes a spark and may ignite any fuel vapours.
Now raise the rpm on the jumper car for a couple of minutes to get some charge into your battery. Most likely you have someone helping you who drove the jumper car so they can sit in the jumper car with their foot on the gas, only a little to about 1200 rpm or so while you get in the dead car and crank her over, it should start easy. If you're doing this on your own then just sit in the jumper car for say five minutes with your foot on the gas to charge up your battery. (Or of course you can pull the throttle lever from under the hood if you know where it is, if you don't know then you'd better not try.) Hope that helps. Best, Guy.

I don't have a Mercedes but thank you for sharing. I like it and think it will be helpful to many

[charlesporter]

I jus brought a 1987 300 same thing crack no start. I believe this is exact issue with mine I will take apart tomorrow or this weekend

[prospexican]

GREAT VIDEO, will it cause any warning or codes? or computers communication problems?

[alexiamora]

Quick question : re: that piece that broke. If I hook up the battery to, let’s say a power pack or a self jumper, will the the car be able to receive power? (As long as it’s still connected ) reason why I ask is because I am trying to figure out if the piece even broke before I disassemble and order. Thanks!!!!

[lincolnvlogs]

GREAT VID! I HAVE A NO CRANK, NO START, NO NOTHING '98 SLK230....WOULD THIS BE A COMPONENT IN MY CAR THAT COULD BE CAUSING MY I ALSO DISCOVERED A "CRASH SEPARATER" THAT I NEVER KNEW ABOUT WHICH IS SUPPOSED TO HAVE THE SAME EFFECT IF THE VEHICLE WAS IN A CRASH OR ROLLOVER. THANKS FOR ANY IMPUT.

[dannyxz]

That's not a SAM module (Signal Aquisition Module), it's a prefuse module.

[chrisoghoanina]

Thanks Very much Gorges. I have a 2016 g63 I have the same issue good battery but no power . The only way I get it is get a boost
Where is your location ? Is possible to reach you

[jamescarrales]

Hi, just saw and like your video on prefuse box repair. I have 2012 Mercedes E550. My electric steering malfunction code shows on dash. I did fuse repair in the prefuse box and it worked for a while but not working anymore. How do I troubleshoot this? Jim

[tonygoncharuk]

Great videos
My ml 63 amg starts good but no power in motorto drive
Do you have any idea what can happen?tanks

[seanwilson]

Holy crap, $50 on eBay. I'm about to buy a REALLY nice 2004 CLK that has a starting issue. A door was left open, lights on, and the battery died. Owner charged it and now it won't start. The culprit may not be the same exact part, but I'm betting it is very similar if not. MB's are known to be sensitive to bad battery charging practices. My (soon to be mine) CLK is waaay to cheap to pass up, given it could be a $50 part keeping it off the road, and in a worse case scenario I can get my money back by selling it as a parts car - it's that cheap. Thanks for giving me a little confidence, George! (Even if that is not the SAM module!)

[garviere]

ha ha ha LOL! I have a door which squeaks like yours. So I'm listening with headset and kept turning around to see who was coming in, was freaking me out til I realised it was on your reecording. LOL!!

[rapphaelclement]
