Hi everyone!
"For some time now, I've been experiencing increasing instances of jerking or stuttering when driving at a constant speed or during light acceleration below 2000 RPM. I can rule out an overly rich fuel mixture, as the idle injection volume is 4mg."
Unfortunately, my ESP still has one potentiometer labeled as RWG. While there are already some slight markings visible on the grinding surface, it otherwise looks unremarkable. Measurements will follow.
That's why I wanted to clean the MSW, but I couldn't figure out how to disassemble it.
On newer ESP units with HDK sensors, there is a mounting screw on the "arm" that needs to be loosened. However, I don't have that screw on mine.
Does anyone know how the arm is attached?

I hope it's not just pressed on.
Do you happen to have an exploded diagram of my ESP?
