amazing repaired mine in 15 minutes starts right up thank you!!

[@projectathos]

Happy to help! Thanks for your support! 🤞💪👍

[@TheArnoldnikolaus]

Did same repair, simply reheated the exiisting solder without adding any new material worked. This part is extremely tiny (for someone who is not working in electronics every day), I was mildly nervous , but it came out ok, same setup that you are using and going nice and easy is key. My tip setting was around 400 degrees. No additional solder used.

[@projectathos]

Yes Sir! I am glad you took your time to reweld and yes it's a delicate fine job. Most importantly is that I was curious enough to actually discover this weird problem... I guess people need to turn that key when cranking with a little less force... 😂 🤣 😁 Maybe they think if they push harder the engine will produce more power! 😭🤣😂😭 Thanks 👍 and good luck🤞

[@samanthagames1023]

Well done, very brave of you. I want to do mine but I'm sure I'd balls the whole thing up.

[@mackeny]

Great video. Just did mine in 45 minutes. To remove the ashtray and radio, you will need a T20 Torx

[@projectathos]

💯💪👍

[@robertbernard5283]

Very helpful video. Just repaired a ML 350 and it worked perfectly.

[@projectathos]

Very happy to hear that I helped you! Thanks for the support! 👍

Thank you.Just finished fixing mine.hopefuly it worked.1st test worked fine.lets see tomorrow morning.

[@projectathos]

Most of the time this repair does work. But I have had a few cases when it didn't because simply there was more damage within the electronics and then we needed to replace the EIS. It's very important this repair to be done early when the problems start. Thanks and Good Luck! 👍

[@weneakhborzable]

@@projectathos yeah,so I might be one of the few cases where it doesn't work. The issue is still there.once I remove both plugs for few seconds and reconnect them,it starts fine.my main issue when the problem happens while driving.all dash lights come on.the wipers go off randomly and gear selector stops working.I have to stop.but while deceleration,the gearbox shifts down very harshly. I think I need a new unit!!

Fantastic work and video amazing one hand skills lol but please start the car at the end so we can see it start

[@projectathos]

This repair was done some years back my friend and the car is long gone. Technically I didn't know whether this repair would work but since I know that there are companies that charge upwards of $400 for this repair! The repair did end up working but I didn't pay attention to record the results. I do have another video later with this same repair on another Mercedes and I taped that the car started at the end... Thanks for your support! 🤞💪👍

Good man fixed my moms gl had the same issue

[@projectathos]

Yeah I have done this repair many times and on many different models that have this switch which most Mercedes have them anyway! Most of the time this works and sometimes it doesn't... Anyway 😂 Glad that you saved some big money and you get to continue driving your GL! Good Luck to you my friend and don't hesitate to ask questions if you need more help! Thanks 🙏👍

[@mustafay4427]

@@projectathos thank you very much

[@manzarahmed1]

Thank you so much for this fantastic video! Did you have to reprogram the key after you soldered the ignition connection?

[@projectathos]

Nope everything worked fine. No program in the memory was lost in process

[@onexsculler]

I did this exact same repair and it totally bricked my GL. It all was very easy, soldering and all but when I reconnected the two plugs to the back of the EIS nothing works. If Michael on EBay can’t bail me out it’s going to be a $1500 bill to get it towed to my dealer and have it up and running.

[@projectathos]

@@onexsculler Your EIS may have been damaged already or in the process of getting damaged completely. Sorry to hear this... Some of these repairs work sometimes and other times they don't because some things are beyond repair. You may have to get that EIS replaced at the dealer...

[@alexk8583]

i have similar problem. sometimes lights come on but it wouldn't start when i turn the key. other times no lights come on at all and it takes a few tries to start. also when i get inside sometimes there's a message "don't forget Your key" i wish You did show how it looks on Yours.?

[@projectathos]

Very similar problems and intermittent starts. But you must check your trouble codes first. I am extremely happy that I could help! Saving money and learning in the process you just cannot beat that... Please subscribe and thumbs up!

[@mjenks85]

I am not gwtting any codes on my ml350 but its the EIS or the key. When turning no dash lights turn on. It lets me turn to try and crank and nothing. We were going to the beach in this car and mechanic is stumped so it looks like we are not at i need to figure this out on my own. Did you get an eis code? Mine is not intermitent it just stopped starting. Im not getting remove key so i think its the key. I do not have a spare.

[@projectathos]

You need to scan the car with a scanner with Mercedes software that reads your car first. Then based on the codes you may get some info what's going on. If you have no codes it sounds like the Ignition Switch itself going bad. I have seen these EIS going bad and not showing codes during the scan so don't rely or expect codes. Follow the mechanism of how these cars work and the modules communicate internally. If it let's you turn but it doesn't start it's not the key but the ignition switch unfortunately... I have seen this situation many times. The electronics inside are not working in the Switch. Does your remote work when you press the buttons? How about the battery in the remote? If it's functioning then it's most likely the EIS. You could ask a mechanic to open the EIS switch and look for broken solders like in this video. If not then you would need to get a new EIS and a New Key programmed to it too at the "Stealership" unfortunately... Sorry again and let me know if I can help you more... Thanks 👍 and Good Luck 🤞

[@dcfrogman]

I have this exact problem. I could use your help. How can I reach you?

[@johnbrennan7175]

So much easier to remove the EIs with R/H drive cars.

[@projectathos]

Maybe not sure. 😁 Never worked on a Right Hand Drive car! Thanks 👍

[@gregorycampbell2594]

@projectdoit1 I burned the small part with my solder iron. Where would I go to get that small white part? Anyplace to order online?

[@projectathos]

Sorry not that I know. Possibly you may get another used switch and transfer the part... Thanks...

[@iraklijorjadze2152]

Hi, Could this type of cold joint problem on the EIS cause first cold start problem in cold weather? At which point a lot of Can problems are seen in diagnostic error codes. And then it is corrected by removing the EIS fuse only. If it is the fault of the microprocessor, only the entire EIS-unit needs to be replaced ? @projectathos

[@projectathos]

This problem has almost no relation to the weather but keep in mind that solders will come off easier when it's cold. So unfortunately I cannot claim completely that the weather doesn't affect the soldered elements. So there's 50/50 chance it may be the cold weather! 2. I am sorry but I don't understand your second question/statement. To try to answer it - you cannot erase codes in the Canbus system especially once created by the modules by simply disconnecting a fuse! Sorry but this doesn't work. If it was that easy everyone would be able to fix their cars at home without the need to use those very expensive software programs and scanners that are needed to scan and diagnose Canbus diagnostic codes. 3. Yes if your EIS is burnt, damaged or whatever else you will need to replace it with a New OEM MERCEDES Part that would need to be programmed by the Mercedes Dealer to your vehicle and your keys! Sometimes you may need to replace your keys with The new EIS because keys are programmed only once. Thanks and Good Luck 👍

[@iraklijorjadze2152]

I will try to explain it differently, in my case the key does not get stuck, the car starts normally, but in a few seconds it writes the problem of everything ESP, ABS, SRS and only if temperature is under 0 C. so if there is frost. and we determined that EIS is causing it, weird, whether it is more likely to come from the bad soldered some pin or from the microprocessor, because there is a resource on KZbin Where the cold affects the microprocessor, kzbin.info/www/bejne/bnu3k4aonNyVjck I am afraid of disassemble and damage it because, then we won't be able to reprogram it to a new one @projectathos Eventually I'll have to take it apart and open it up :)

[@modified15r]

@@iraklijorjadze2152 Did you figure out what was wrong? Getting same symtoms with multiple CAN codes and intermittent no start.

[@jackycheung412]

Hello, thx for your great video, I Hv the same problem of my w164 with code C141! Is it the same as yours ? Thanks !

[@projectathos]

CODE 141 MEANS - NO CAN MESSAGE FROM CONTROL MESSAGE N73 ESZ IN TCM. TCM IS THE TRANSMISSION MODULE. THIS IS A DIFFERENT CODE. RESEARCH IT ONLINE TO GET HELP...

Thx for your speedy reply! I CAN’T find any information about this , can help?? Tons of thx 🙏

Great video. That wood panel is filthy on center console

[@justinyu7]

is this only for ML? does it apply to C or E?

[@projectathos]

GL and MLs ia where I have seen this situation but technically these EIS were also used on the E classes I believe too. You would need to disassemble the switch from whatever vehicle and investigate it to confirm. Thanks 💪👍
