In this video Fix your Mercedes will be showing you how it looks like being an advisor, a diagnostician and supporter for a youtube friend helping him repair the Mercedes R107 500sl. The car wouldn't even start as it came to the garage. After some advice and a hard work of the owner the car started but it held constant idle of 2000rpm. Bit by bit the owner repaired that issue, the cold start valve wasn't operating - the issue solved. In the video you are going to see how everything looks like with the pictures of the car, video clips showing a non starting car, the car holding idle at 2000rpm, a car that starts and holds steady idle as it should and at the end the same car that even didn't want to start now accelerating. Enjoy the V8 sound of the Mercedes 500SL while accelerating.
One more car fixed and happy running at the road - Happy Mercedesing!

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.
