Mercedes KE Jetronic - The sensor plate way down on your Mercedes? Is it maybe just a spring?

An easy fix - Your sensor plate fell to low and won't go back up so you don't know the cause why. You have both warm and cold start issues? The car cranks but won't start or it starts very hard? Your issue may be a loose spring that preloads the spring to hold the sensor plate. It's very easy to solve the issue, the most difficult part of the job is going to be to take the airflow sensor out of the car. Many screws to unscrew and a whole day in front of you to do this job but it is well worth it because this kind of a repair costs at the dealership 600euros/over 700$. With this video as guideline and a whole day in front of you, you can save 700$ in one day.
For this operation you will be needing a wrench 10mm and a torx 30.

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.
