In this video I explain how to tell which part is bad operational. The goal of my videos is to show you how to repair your KE-Jetronic car in your own garage using common tools. The part that has to be replaced you will have to buy and it depends on you if you are going to buy used or new, branded or not branded parts(which is not my advice to you).
And an important announcement: If you are of those who want their car to be diagnosed and repaired in half an hour, or you don't like popping up the hood and getting your hands dirty, then a KE-Jetronic car is not for you, either a Mercedes or any other KE-Jetronic car!
IF YOU DON'T KNOW HOW TO USE A MULTIMETER OR WHAT THAT IS, IF YOU NEVER UNSCREWED A SCREW OR WHAT SPARK PLUGS SERVE FOR, THEN BETTER DON'T BOTHER YOURSELF WATCHING THIS VIDEO, IT WON'T BE OF ANY USE TO YOU!!!
Repair your KE-Jetronic injection system in your garage or in front of your house using common tools. This tutorial is going to guide you how to diagnose an error on your system starting from its mechanical part up to its electric part using just a multimeter and a pressure gauge. You can do it yourself and I am here to give you nominal values and some useful advice. You will be surprised how easy it can be to repair your "girl", although you can't repair this system "just like that" without knowing anything. Do it once and you will be calm in next five years or 30k miles(fuel filter and lambda probe) and afterwards in next ten years or 90k miles you are going to experience first major issues(potentiometer, fuel pressure regulator, injectors). Not many mechanics know about this system and if they never read anything about it, then they won't be able in 100% to understand the way it works and then neither to diagnose it nor to fix any of its components. On the other hand, those same mechanics don't want to bother themselves with this system because if they knew how to repair it, they wouldn't do it, because todays cars are lot easier and faster to be diagnosed and repaired. Well, that's where I start!

What am I talking about?
My topic is the KE-Jetronic injection system which I try to demystify as much as I can.
For all of you to understand the system in brief - Developed in 1973 and being mounted into cars up to 1993 as it went in history. But why these to letters!?(KE) K(from German "kontinuierlich" meaning continuos, without interruption) the MECHANICAL injection system on which the fuel starts flowing from the fuel tank sucked by the FUEL PUMP and delivered to the FUEL DISTRIBUTOR which sends fuel to the INJECTORS while the majority of it flows through the FUEL PRESSURE REGULATOR through its return line back to the fuel tank again. The letter E(electronic) has to mark the electronic sensors (the developement starting from early eighties) which had to inform the ECU about the current state of the engine so that the ECU(Electronic Control Unit) then could create current signal in mAmp(miliampers) and send it to four crucial components for the system - the EHA(the electro-hydraulic actuator,a unit consisting of a magnet, an electromagnet and a baffle plate) which had to fine tune the engine in each of its phases, the ICV(the idle control valve), the unit which was predicted for the engines perfect idle, the X11(the diagnostic socket) where the duty cycle(the ideal mixture) was adjusted and the X11/4(the code reader) - the socket which from any codes were read if present using an OBD1 scanner.
An extraordinary injection system which could be fully repaired in your own garage using a multimeter and a pressure gauge only for its fine tuning, together with some common tools.
"Happy Mercedesing"

I want to make this channel a nicer place for people - its goal is to make people happier, solve their problems with a mechanic fuel injection called KE-Jetronic. I would like this channel to be place where people are going to gather and become friends, solve their problems concerning their cars and help other people solve their problems in their comments. Any other speech of hate, poking, pornographic advertising, curse words won't appear on this channel - this also goes for serbian language which is full of them.
Reci koje upucuju na polni odnos, felacio(u bilo kojoj varijanti), vaginu, psovanje majke, penis(u bilo kojoj varijanti - sa zvezdicama, slovom q umesto slova k...) Everyone who orders me what to do without a "could you please", or how ever you want to ask a person for something will be reported to youtube and blocked!!! There will be those who will be allowed to tell me a curse word but that status they will have to deserve, THANK YOU!
Bice i onih koji ce moci da mi kazu to, ali taj status moraju da zarade kod mene! Hvala!

The person who say they do not like this video has to have a personal issue with the maker of the video. This video is a wonderful video and its thumbs up one hundred.

[joeymusaki]

Many, many thanks from Germany, my W201 needed repair, I had no idea where to start and what to do, the KE-Jetronic is nothing for total beginners like me... Now many thinks make sense, I never figured that out, not in a million years... Two thumbs up!!

[AliAli-cpem]

I am from libya . Thank you . For intreduce . We are saticfaid from you . Thank for you again .

[wiktorgsxr]

The best video around the word about ke jetronic

[armandomartinsanchez]

Good Job Ivica. I will see again and again to learn every part. I got problems with me 230.

[Ozkan_Ozturk]

thank you Ivica for these step by step explanations with pictures/videos. Some people may not know what that part is and its location. So your explanations are helping. The more we have great Mercedes running around, the better it is for every owner. Want/Help your friend`s Mercedes run better, then your Mercedes` value will go up. I am sure many followers will join your channel & donate from US, too, so as you did before, pls always warn them: USE ETHANOL FREE PREMIUM you will get all these parts failing faster than normal.

Thank you so much for your great video's. I learned a ton! I was looking for information to solve a starting issue on my W460. These are the most informative video's on KE Jetronic systems by far! Keep it going. Greetings from the Netherlands

[Bacardiblack]

from Türkiye İ have w124 1990 i am realy happy to find this channel to understand ke- jetronic system

[MAGNESIUMBURN]

Thanks for sharing the tips on the fuel pump!

[pintoscott]

The "Best". Simply the best explanations ever. Out of the many (did I say...Many) videos I have watched on Mercedes Benz traying to learn and fix my Mercedes, Wiktor No sarcasm, plain explanations, and extremely useful "how to" descriptions. Thank you Wiktor.

[LucTheDuke]

Thank you I got a lot of good info about my Mercedes r107 system

[jsegura]

Thanks again for all this great information.... Hi from New Mexico USA.

[firoxlion]

Thank you so much, this is a great detailed explanation of the KE system. And awesome that you included all the measurement values in the video :)

[JosephAndeka]

Thanks for the video. Very clear and informative. I didn't hear much about the test for the TPS and it's effect on the engine if it needs to be replaced. Greetings from Naivasha - Kenya.

[carlaanddonbrantner]

I live in Show Low Arizona in the White Montains I love my car and want it running right thank you so much for all of your videos!

[Artsalloverone]

Just wanted to say thank you for sharing your knowledge of this fuel system Mercedes uses to power the w124 and w126 it has helped me to understand how the system works and functions with all the components..👍👍😄

[arslna]

Wow! This video will help so many of us. Thank you sir for such a great video and teaching us.

[hans-petterkarlsen]

Wish I could get you to troubleshoot my 104.981, runs like crap, stalls, and wont pass 3000rpm.
Glad I found your video

[saintgermainyyz]

currently diagnosing my 190e ke jetronic and this video is amazing, going to test everything from start to finish and see why it doesn’t run well, and has inconsistent start and idle patterns
