㉦Mercedes Ke-Jetronic㉦ - How the Idle Control Valve Evolved (KE1 to KE5 Explained) #fixyourmercedes##idlecontrolvalves##viralvideo Instagram:   / fix_your_mercedes   TikTok:   / mercedeskeje   In this video, we dive deep into one of the most fascinating parts of the KE-Jetronic system — the Idle Control Valve (ICV). From KE1 to KE5, the system evolved from a mechanical valve with a simple bimetal strip to a fully ECU-controlled electrovalve. ⚙️ You’ll learn: – How the ICV design changed through KE-Jetronic generations – Why early systems allowed manual idle adjustment – How the ECU took control of the idle on later systems – What you can (and can’t) adjust on your own 💡 Tip: If your idle is unstable, check the TPS, lambda sensor, potentiometer, cutoff switch, and vacuum leaks before touching the ICV. 🧼 You’ll also see how to test the ICV with a 9 V battery and how to clean it properly using carb cleaner, Q-tips, or diesel soak. 🔧 For M116 and M117 engines, there’s still a manual way to adjust idle — but that info is reserved for my special subscribers 😉 📺 Watch till the end and don’t skip the ad — it really helps me keep making these videos. 🏁 Until next time — Happy Mercedesing!
