2011 MERCEDES BENZ E350 (W212) DIESEL NO CRANK | RANDOM LIGHTS ON DASH | CLEARING CODE FIXED CAR?

[@SuperMarioDiagnostics]

People seem to think that i didn't attempt clearing the codes to begin with. CLEARING CODES DID NOT FIX THIS CAR LOL! I did clear the codes after saving my prescan, AT THE BEGINNING, as i explained in 34:45 The title was meant to be a joke!

Mario! Videos like these are why you are showing you are as skilled as guys like Pine Hollow Diagnostics and Diagnose Dan and Scanner Danner. Always enjoy exploring issues with you taking us along for the ride.

[@kennedysgarage3281]

Very well said TJ, everyday is a school day & I really enjoyed this video. Thanks Mario 🙏👍

[@tyhoang63]

Mario Rojas is the best diagnostic technician in my opinion. He works on the very intimidating Euros which in my opinion is a lot more difficult to diagnose than other vehicles. Great work. I’m always learning from you. Always very thorough and detailed with his process. Much love from Toronto, Canada

[@FuManchu5ltr]

On a more serious note, I’m learning so much from channels such as this one. Thanks for rambling. Thanks for taking us through this.

[@billytremoloband7456]

Just started this vid, it’s going to be a roller coaster of exciting no doubt! Mercedes diesels are great but when they go wrong my god do they test one’s skills !

Mario thanks for sharing. That vehicle looks like an electronic nightmare. Thanks for sharing your diagnostics process. Stay safe and well Artie 👍

[@scottjhicks]

Well done Sir! That feeling of being wrong hurts those of that take this serious a lot more than others. I know guys that just don’t seem to care. I know when I mess up I am way harder on myself than anyone else could be. That’s also why I am always learning.

[@marcosmateo8439]

I love watching your videos. I just learned also with BMW short circuit codes on the Footwell module will also lock out that circuit from working after so many counters permanently thus having to replace the module. I hate to be wrong too is suck kick in the balls. Great work man!

[@r.weaver3769]

My W212 has no steering lock, no emulator and a foam block where steering lock should be. Also, I too learned about clearing codes to reset computer, had a misfire, replaced coil and misfire remained. The computer shut down the fuel injector, once codes were cleared misfire was gone. I too about had a breakdown, as the intake manifold covered the back coils.

Dang. So was the little AES scope itself at fault? Or was it a bad connection? The BNC? The wiring? The cables? I own an AES scope and would hate it if the unit itself was faulty....... Thanks, Mario!!!!!!!!!

[@SuperMarioDiagnostics]

Usually it's the cable

[@MasterTechLou]

really curious why you are using alldata when you have access to star wiring, I used to yell at my new hire that came from midas, he would always use alldata instead of startekinfo at the dealer. alldata is terrible for european cars. terrible. like, terrible. did I mention it is terrible? :) I normally dont comment on channels, but I been poking through your videos. Hard to find good honest people such as yourself and myself, so keep it up man. Lou oh p.s also, what may have happened with clearing the codes, is all you may have needed to do was lock the car and unlock it to make the car sleep for a quick second so when you unlocked it , it would recheck the systems. We have seen this more and more where you have to do that, or the issue will remain. in the most randomness of systems.

[@SuperMarioDiagnostics]

Startekinfo is highly inaccurate on its own Out of all my videos, this is literally the only time i had to use factory service info Alldata is very strong on euro, when you know how to use it Just my opinion!

I wonder how Hanz and Franz decided to put the Engine Control Module in the wheel well. Did they just put all the harnesses together on the car and ended up with the ECM connectors somewhere in the wheel well?! “ Ah let’s put it here Franz. “ What could possibly go wrong?! Heat-check. Vibration-check. Moisture-check. Corrosion-check.

[@V10PDTDI]

Hi thanks for the video recently I got a 2017 GLA 250 in my Shop and the instrument cluster was doing strange stuff like the outside temperature was reading no temperature just 3 bars and a multiple warning light was coming on and off intermittently especially when the car was running for a while I put my scope on the can bus under the driver’s seat on the seat module and when the outside temperature was ok the can bus signal was normal but as soon as the outside temperature gauge was not functioning correctly the bus signal very erratic the same with the warning light I found the interior can bus connection behind the instrument cluster on the left and checked for anything abnormal and all was fine but when I would touch the can bus Connector the signal would sometimes be affected I ordered a new distributor like Mercedes call it and it fix the problem I saw nothing wrong with the old one and since they are high and not sitting under the carpet like a lot of other Mercedes cars it was just defective there are very little in this part a couple of soldered parts not sure what they are but it’s a lesson that these things can failed without any water damage.

[@ousmanesarr7287]

Hey there. Strangely iam dealing since 2 days with a w204 c300 gas engine v6 .was called in a shop to diagnose as a no crank with all dash errors on. We have the same exact scan result .I mean to the letter. Missing srs - engine computer- electronic shifter fuel pump module and tcm the scan. When i saw the chassis can fault on the central gateway , i looked computer data diagram on prodemand and notice that most of the modules(: ecm tcm electronic shifter was) on can c wich is blue and blue/white wire. Scoped that can c and guess what perfect signal like you saw. Spent next 2hours looking factory diagram ....and c checked power and ground to ecm.ecm 5v ref....and couldnt for the sake justify why ecm wouldnt talk as its a gateway and have more that 1 can network connected to it. .thats when i noticed something very important. CHASSIS CAN IS DIFFERENT FROM CAN C. CHASSIS CAN IS CAN E AND IS GREEN AND GREEN WHITE IN COLOUR. Scoped chassis can and voila can is shorted. Located the chassis can connector on driver floor panel lifted the carpet found a pool with connector submerged in water. When Chassis can is down on these. Can C ( drivetrain) wont operate even though it scopes fine.. i think the front sam needs chassis can to be operational for can C to transfer data.

[@ousmanesarr7287]

And the obd connector is wired with canD ( diagnostic can) . And connect to front sam. Wich is the main gateway on this vehicule.all 4 to 5 cans go to front sam.

[@nkonyanechristopher]

Its bold to be honest with your videos

[@pmgear]

what would have happened if you just cleared the codes? did you put back the old computer to see if it was actually broken? Thanks for the video, I learn a lot every time.

[@SuperMarioDiagnostics]

As i stated, right after saving my prescan, i cleared the codes. The original module is no good

[@pmgear]

@@SuperMarioDiagnostics thanks for clarifying, I missed that.

[@dbash2004]

I haven't got a scanner it tells me on the dash and I think if you're not experienced at using a scanner for the codes it can cause more confusion than solutions. Just remember what you learnt about cars and eliminate the systems one by one

Nice diag bro! Where did you find the Mercedes-Benz factory wiring diagrams???? Eres un genio hermano!

[@SuperMarioDiagnostics]

Thanks, It's from the Mercedes site

[@jtuominen72]

Is it possible that the old module would have worked just by clearing the codes? Because the initial symptoms with the new one were exactly the same as with the old module before clearing the codes.

[@SuperMarioDiagnostics]

As i mentioned, i cleared the codes after saving the prescan

[@waltermiller8849]

Good job and great thinking. Question. The codes come from and stored in that computer (ECM. BCM ) or what ever. When you change out the computer why did it not clear or there should been no codes on new computer. Thanks

[@SuperMarioDiagnostics]

The codes in question are from other modules including the gateway

[@mikechiodetti4482]

You found the bad module and now it's fixed. Why did the module fail? Was it moisture, pin contact or internal damage?

[@SuperMarioDiagnostics]

Internal

thank you. great channel informative

[@mayowaodus6310]

Hi Mario. If there is a short to ground on one of the CAN network. Can this affect/damage any of the computer on that same CAN network. Nice work you are doing

[@SuperMarioDiagnostics]

It usually won't damage anything. It will cause lack of comms to everything in that network. But if it's only one wire, it may go into fault tolerant mode(single wire mode) and still communicate. But since its only one wire, there will be no noise termination, so you'll have some issues with interference or repetitive messages etc. But this will typically not permanently damage a module once the short is removed

[@jwoeltje6949]

Are you claiming that uscope only has 6 to 8 months of reliability? I’ve had mine for about 13 months and it just failed. Approx 23:34 mark

[@SuperMarioDiagnostics]

No not the uscope itself, just the wiring

[@alekstolstoi]

where can i get this software and tools that you use for prigraming ecm?

[@SuperMarioDiagnostics]

It's called flex from magic Motorsports

[@jeremyah78]

Mechatronic Mario! On the bleeding edge man! I’ve never heard of that magic flex box before. How is it different from a j2534 pass through tool?

[@SuperMarioDiagnostics]

It's a cloning programmer, one of the best in the market

[@jeremyah78]

Got cha. So in the case of a corrupt, or otherwise dead module from which to clone, you would have had to have access to OE software like with a j2534 tool, yes? I know in this particular case, your boss had a replica file for the flex to read and write, but if he didn’t, would that still have been the tool to use, or would you shift to a j-tool? I know you kinda touched on it in the video, but I wasn’t quite clear about what you meant. Sorry to take up your time Mario… not to worry if if the answer is more elaborate than a simple reply will do justice. I’m just curious because in my limited experience with it, programming with a j-tool is generally a pain in the arse! I’m really quite curious about better options on the market.

[@SuperMarioDiagnostics]

@@jeremyah78 a jbox won't Finnish the job for a Mercedes. If there was no file available to clone from, a used module could be reset, or otherwise coded to make the factory software to believe that it's a new module, and the module would then be personalized, activated and coded to the vehicle. I personally haven't tried the Mercedes j2534 software. It may do the job, but i have my doubts. We use sdconnect c4 with xentry Will be upgrading to the c6 soon

[@jeremyah78]

@@SuperMarioDiagnostics Thanks so much for your time, brother! Very helpful information! ✌️

[@jaredbrooks9926]

Just wondering if disconnecting the ECU before you carried out any tests would have zoned in on that ECU. I would have thought most of those codes would have dissapeared ? Perhaps you did ? Either way nice job.

[@SuperMarioDiagnostics]

Since it's the gateway, disconnecting the ecu made no change

[@billytremoloband7456]

Is it possible to program in new ECU’s on the Mercedes with the Autel……? 🤔🤔🤔

I've done used ones with me9.7. Haven't tried cdi modules. And no it won't do a brand new module, at least the im608 won't. Not unless you pull the coding off the original module. But again i haven't tried a cdi

Hi! If you didn’t have the back up file, could you have copied it from the original ecu? Or you couldn’t copy it from the original ecu because it became defective? And if that’s the case, could that have been a confirmation that the original ecu is defective since you could not copy the files and make a back up with the flex? Thanks!

Couldn't copy from original

So if you couldn’t copy from the original ecu, is that another confirmation that the ecu has to be replaced?
