Well I think u did a good diagnosis,

This is happening to the models that use that system from around those years, EVERYONE report to NHTSA and to MBUSA, they have to fix this for free or a CLASS action will cost them more

Well-done

It's not easy to find info on Merc's period. However this guy know his S 4sure. Excellent info presended as best as you could hope for as this is not easy to understand more/less get across in a video what steps you're going thru in your head. Cheers, glad I found this channel. If I could impose for a question; remote appears dead, When inserted get nothing (don't hear servo for I assume is steering lock &/or shift) no cluster activation either. I am thinking power/fuse, but I am conserned about bunch of after market crap been installed/uninstalled (scotch locks) all about rig. Yeah, not good. Anyway, your thoughts would be fantastic. Thanks

Thanks for the information. 👍

thank you

My car came with two keys, one did not work, I took back to dealer and got a new key, this could have been the issue with that key. But I have two keys now, so... Thank you!

Thank you, i have same issue.

Hi 👋Sir, very nice video

Is there any way you can post a video on how to take apart the mercedes key without damaging

Good video bty!I have 08 c350 Benz but instrument cluster not working any advice for fixing or diagnoses??

Hi Mario. Have similar issue. Can you please confirm. When key in not turning to access obd to read need to turn hazards on?

Hi I have a 2010 Mercedes Vito with intermittent key not been recognised, I’m I right in thinking if I use another Mercedes key not for my car and try it and always get the message key not recognised all the time that pretty much means the EIS is good and my key is the Issue, great videos 😊

2010 c300 good alternator but not charging is there a fuse or is it the one that goes from the starter en then to the cluster?

Your a genius, Thank you!

Just looking forward to the dramas the ev's will bring. What was the matter with just turn your ignition on with a bladed key and start the car?

Bad ass Mario 👍👍👍Thanks for the advices

I'm looking to figure out how to get the radio to work on a 2012 C300 class it doesn't work at all the instrument that the panel works and everything shows it but can't get sent out of speakers can you help me with that

Gracias Tengo El MISMO problema ya se como hacer

Thank you for the info my car is not starting sometimes and I just notice that battery might be low and the key chip is not being recognized

Hey Mario my Mercedes S500 2003 key works when I stick it into the car ignition the clusters respond all the lights and radios work still no crank took it to a shop and they said it was ECM computer AFTER A RAIN STORM and drains were clogged.......any thoughts

Hi my w204 c350 2010 starts in the morning when the engin is cold but when it's hit it just crank and wount start but if I put jumpers on it it starts if been to many people and every on tels me a other story dit replaced the glow plug module it was fault my obd picked it up

Good video marito tengo una 2014 sprinter y da ignición pero no arranca . Será que el eis corta el diésel por que le pongo marcha directa del + I solo gira y no arranca . Me ayuda por favor primo ? Muchísimas gracias .

What a good tutorial on DAS ! On a 2008 W204 GLK280, Steering column clearly unlock when both keys are plug in, In second contact position, a message appear: "ESP inoperative and run flat inoperative" and engine will not start, Xentry show ME9.7 N3/10 Control Unit isn't awake, unable to ask fault codes on it. On EZS, A valid vehicle key was detected YES Start enable for control unit 'ESL' is issued YES Start enable for control unit 'ME' is issued NO Start enable for control unit 'ETC is issued NO Sometimes this message disappear, engine starts, and "no CAN combustion engine communication" fault code is recorded on ESP, FSCU, ESM, VGS and IC. Fuses, relay, CAN lines have been checked. I want know if I replace N3/10 ECM ME9.7, N10/1 front SAM, N73 EZS or ELS.

Good day, is the ignition not supposed to be on for you to able to scan, how do you scan when the ignition is off?

Hey Mario a big thank you I have a family member came to visit what A 08 C300 Went to shopping center car wouldn't start had the car towed to my house I am a Tech worked in many garages but you definitely led me in the right direction I definitely think I will try and get a new key programmed or if you can give me a shout back if you can help me with keys please let me know

when i insert my key in on c300 it says remove key from ignition.. i took my car to the mechanics and they said they have to replace ignition steering lock and steering column. and i have to pay $1 100 to fix. I wanted to do it myself but it is a lot of things and steps to do and i don't wanna mess my car up..

👍👍👍

Exactly the problem I'm having with my 2010 C300 Mercedes now.

@Super Mario Diagnostics I have the same Car/Model W204 mine was okay all the way although it didnt Crank at all Then the Tech came and all he did was reInsert the Relays and Fuses in the Front Fuse Box and Reset ECU and it started again. No faults prior and after. What could be the problem? He is hinting thay it could be with the Front Consumer inside the Fuse Box itself that it might have gotten moisture.

Thanks for the awesome content Is there a way to check eis functioning with im608 Dealing with W210 02 clk Both keys unlock car Eis wouldn’t turn at all Cluster not showing anything Els not unlocking I tested both keys on Autel both working fine Took eis out and program new key still wouldn’t turn I’m thinking I have to program new eis What do you think

Obviously you've seen this problem before, which is a big plus for your diagnosis. Without the info in front of me, I did somewhat understand your path of diagnostics and how the "start" signal flows from the key to the starter. Would a wiring diagram and/or service information have helped to locate the problem? Or did you take the time on your own to figure out how the system functioned?

Hola, tengo un 2011 c300 no me sale la llave del timon? Que podría ser?

👍👍👍👍

Nice breakdown my guy . I like my Triton but that Autel shows more of what I need . Wife’s Mercedes is giving all the signs of a bad els , but I’m going to test the starter just to make sure

Xentry has a test for the drive authorization, works slick. Identifies faulty column locks and eis in seconds.

Super mario , why does my starter fuse keeps popping, no crank

Hi there I have a issue with my Mercedes clc cdi 220 2009. When I turn the key full turn to start the car all lights come on and the needles all move up and drop back down again but the car will not crank, I then turn the key back to position 1 then turn to position 2 leave for a few seconds the turn all the way and the car starts. If I'm in traffic crawling sometimes the car cuts out I have had 4 different mechanics do diagnostics and had the crankshaft sensor changes ,I've had the key and switch checked and tested and all is fine. I have spent around £400 so far trying to get to the bottom of this issue but no mechanic can seem to fi d out what the problem is and its getting frustrating now. Have you got experience with these cars and do you do full checks to what can cause a issue like this?

Hi, for this exact same vehicle I have a major issue 1 : after doing an online programing of the ecu and front and rear sam , it suddenly says hood sensor no com and back seat rest latch code comes on ( previously before the online programing no such issue and even the car hood doesn't seem to have Been equipped with any sensor for hood warning for my 2009 w204 ) 2: I try to activate the teach in drive authorization and when it gets to the part when it says start engine and allow to idle for 30secs , the Benz won't start until I turn the key back off and try to start it again before the engine will start which at this time the process fails , I'm using the launch immo elite , also launch pad vii and topdon phoenix plus , yet no success, please I really need your help

My new to me 99 W210 had intermittent no crank no start. Luckily, it was not DAS related. Turns out K40 relay control module was bad. Swapped out the complete unit. Should have tried swapping starter relay first but the complete K40 was $25 from the junkyard so in it went. My TCM had fluid wick. Any fluid on the connector means there is some inside the module. I opened my TCM and cleaned PCB and case. Plastic harness connector in transmission is not sealing and has to be changed.

Thanks for you time and like the video about the micsigAto1104 just got one first scope hope to get good at using it

Will you please repair my key fob for me? I have a 09 Mercedes c300 with the same problem.

Hey love your channel brother, I'm an infiniti tech. Quick question how are you communicating with the car and the keys off? my snap on triton d10 will not communicate with koffeo. Is this a Mercedes thing or special function of the autel?

Where are u located

Perfecto👌 Amazing the way you attack these European vehicle's is superb👍 Sorry due to lack of internet services in my area, I'm not able to watch all your video's on time, but I'm trying to follow-up with all the viewers😉 Thanks for sharing Bro, Stay Safe👍

Awesome video with explanation. I have both the keys and when I insert it wont crank up. But the center console lights up. Really don't know what to do.

Can i have the scanner

why have the hazard light on???.

I have a no start nor crank remove key lights up on the dash

I have a 2010 MB C300 and with the same issue. The car doesn’t turn on. I insert the key and the dashboard pops up “remove key from ignition.” After several attempts in trying to start it, the dashboard changes to only show the mileage. After several attempts the car will eventually turn on but sometimes it takes hours. I only have one key for the car. What do you suggest I do? Thank you!

Not trying to step on any toes here. There are micro switches and hall efffect sensors inside the EIS. When the key is inserted, the "slider" pushes up on a lever closing one and when the fob gets turned there are others that get activated. This is the mechanical status the EIS needs so it knows what position the fob is in. And is what you are seeing on the left hand column of the scanner during the first scan.

My car is turning over and cranking but not igniting..can some one help me please

My Benz just did this the other day, was running fine, shut it off and it wouldn’t start after, so I bought a battery and changed it out, and still no start everything comes alive when I put the key in but won’t turn over when I turn the key, any pointers ? Everything was fine before I shut it off , and it wouldn’t start again after

Hey a Mario I have a 07 clk 350 el carro se apagó solito y ahora prende el tablero y actúa como si la batteria estuviera weak… tu k savez d esto que se chequea ya que as visto d eso problema con con los venz

Amazing video! 🙌 Since removing the battery and reconnecting after few hours my car does not start now only opens and closes windows, car cluster goes on but does not change when key is turned or accessible either setting etc. After a few days only one out of the two keys open the doors. Any suggestions are appreciated 😁

Having the a similar issue with my 2012 c300. However when i put the key it just tells me to take it out. Lights turn on so does radio car locks and unlocks. But wont start. Wont even make the motorized noise when I first insert the key like it always does. Turn the key nothing try to start it nothing but everything else works. What can i do ?

I inserted my key and all I got was “dont forget your message” this means my key fobs still good?
