Great Video! I've had the hardest time getting my car to start. I had been through all the tests, and everything had checked out. I suspected it was the mixture control screw but couldn't find anyone out there who could advise on how to properly perform an initial setup on this. Also, they don't talk about this in any of the K Jetronic manuals that I have. Your video was exactly what I was looking for. I followed your procedure, and the car started right up! I can't thank you enough for taking the time to make this video! THANK YOU!
@@mercedeske Thank you for your support with my G Wagon with the K Jetronic! I DM’d you on instagram, I understand my air flow meter is bad and would like to know which one to order.
Hey Friend, learning a lot from you about the FI system on my W124 (US spec 1991 300CE). I recently took apart the wiring connector to my EHA and did not mark the wire locations :( Can you tell me which wire goes to which terminal on the EHA? Black wire and black/brown wire.
Hello and thanks a lot. The black wire goes to nr1 on the EHA CONNECTOR! and the other end of the wire is to the ECU PLUG nr.12, the black/brown one goes to the ECU CONNECTOR nr.10! and YES, DON'T SWAP THEM!!!! Practically the CONNECTOR nr1 of the EHA goes into the EHA pin nr.2 and the EHA CONNECTOR number 2 goes to the EHA PIN nr.1. THE BLACK WIRE goes to the EHA PIN nr.2!!!! Greetings from Serbia and good luck!
Super! So just to make 100% sure, my black wire is on the #1 position of the little plastic connector that is attached to the wires, which corresponds to the #2 pin on the EHA. If I’m standing on the exhaust side (US passenger side) of the engine looking at the connector, black is on the right (closer to the front of the car) brown/black is on the left. Is that correct?
The moment you do the adjustment then you start turning the screw clockwise until the car almost dies, then start turning the screw counterclockwise until the same thing happens, remember how much you have been turning the screw and take the average value. For example you turned the screw clockwise for 45 degrees and the car wants to die, then you turned half a turn counterclockwise and the same thing happens then after half a turn counterclockwise turn the screw 45 degrees clockwise. On the K-Jetronic system you can manually adjust the idle so bare that in mind as well.
Hello, i have learned so much from you and i appreciate that you are helping so many people to unravel the KE Jetronic mystery to make it understandable! However, i recently cleaned my throttle body on my KE3 Audi 2.3e and my idle speed went all the way up after that, to 1200-1500 rpms (it was 800 before cleaning). I have checked for air leaks but can not find any, everything is air tight and throttle cable is not stretched. Car runs and starts great otherwise, is there any adaptions that maybe stored in ECU or what do you think? Remove battery terminal over night? Huge thanks again for all your knowledge and dedication!
great video! im learning a LOT from them!! iv been asked to fix this problem on 1992 190e 2.0l ke-jet do you have a video on how you bridge the fuel relay?
I did the initial CO adjustment like you described but I do not have any play in the plate then. If i want to have a 1.9mm play in the plate i need to turn it 4 times counter clockwise. So i don‘t know what would be the right initial setup or if anything else is wrong.
4 turns is too much. This procedure is being used if the CO screw has been readjusted otherwise the screw should not be touched at all. If you have turned 4 whole turns counterclockwise start turning the screw clockwise until the car starts. As it does wait for it to get to the operating temperature ad set the voltage on the X11 port to fluctuate 6.6-7.3V. At that point you will have the right mixture.
@@mercedeske thanks again. I enriched the mixture now little by little like you suggested. The motor will now start and i can keep it running by playing a bit with the gas pedal. If i release the pedal it will directly die. I also checked the fuel pump relay like you described but that doesn‘t seems to be the issue.
I would love to know how to bridge the fuel pump. My case is exactly as you described it on the video, i started to move the screw and now i can’t start the vehicle(1983 500sec). I don’t know a lot about cars, still learning. I know even less about electricity so I really need to know more details about the step 2 😊
@@mercedeske thank you. So I have to connect pins 87 and 30 from the fuse box back all the way to the fuel pump right?(the fuel pump in sec is under the back of the car)
@@tysiu1681 Not from the fuse box. Remove the fuel pump relay. It's located at the center of your windshield by the firewall, take a simple wire and connect the two contacts, that would have to be the last(third) pair of contacts looking from your left side!
@@mercedeske By the way I don't think you described the proper location of the relay. Like I said my SEC is a 1983 model so it's pre-facelifted. I think the facelifted models (1985+) have their fuel pump relay located exactly as you described it :). In my case I found my relay in the fuse box and it litteraly has all the pins with some certain descriptions like 87, 30, 87k etc. (7 in total)
If the car won't start at all check at first the rubber hose which connects airflow meter to the idle control valve. When that hose falls off the car won't start at all which means that the mixture is too lean and there are going to be detonations. This video is predicted for those who messed up with the CO-screw, which car won't start and who do not even know in which direction to turn the screw to get it back as the mixture is supposed to be! This explanation is NOT predicted for those who just want to play with the mixture not having any other job to do!
My car wont start when the rubber hose from the airflow meter to the icv is connected. I Can only turn on the engine with a vacuum leak going to the icv… help?

So the mixer screw also adjust sensor plate or sensor plate adjustment different?
The mixture screw adjusts the sensor plate.

@mmarzynski Exactly
how can i replace the mixture adjuster screw? i believe i damadged it ?
K- or KE-Jetronic?
Howzit, I got a question, so if I had to tighten the scwer it will give more full and loosen it to give more air
Exactly
Thanks , what is your the next step?

Hello and thanks for the compliments. Concerning the issue - try checking the throttle position sensor to see if it recognizes both positions.
Where is the throttle position sensor?
Problem was at the potentiometer, he has made a lot of videos about it :)
Hey the fuel keeps flowing out the port everytime I bridge the fuel pump. I have a video of it let me link it down in the answers😊

Did you check the WUR whether it is in specs? Did you do the initial mixture adjustment?
Have fix The cold start! Starts weery easy 💪👍
@@jarmominkkinen9409 Glad to hear that!
Bravo King of KE🤴👌👋👍

When you mean fuel flowing out the port, does that mean overflowing or just starting to see fuel coming out?
As you see fuel coming out, it doesn't have to be overflowing.
great video! im learning a LOT from them!!
