The Mercedes EQC Hack Worked… But There’s a Problem

We thought we cracked it… 😳 In Part 1, we managed to bring this Mercedes-Benz EQC battery back to life by going completely outside the box. No replacement. No new parts. Just deep diagnostics and a solution most wouldn’t even attempt. But here’s the problem… 👉 It’s still not perfect. In this video: We refit the battery and test it on the car Check if both battery packs are finally working together Monitor cell imbalance under real driving conditions And uncover another issue that raises even more questions… Is this battery actually fixed? Or is there a deeper problem hiding underneath? 😬 👉 This is where things get interesting. ⚠️ As always, all work is carried out with proper safety procedures and equipment. 📍 Visit Us: OGS Mechanics Units 9–14, Millers Yard Rear of 28 Long Lane London N3 2QG 📺 Watch Our Repairs in Action: 📌 Subscribe on YouTube → Weekly EV/Hybrid breakdowns, fixes & full diagnostics #MercedesEQC #ElectricCar #EVRepair #CarHacking #CarBuild ⏱️ TIMESTAMPS 00:00 – Reassembly Begins 00:20 – Battery Back On the Car 01:10 – First Startup… What Happens? 😳 02:10 – Range Looks Good… But Is It? 03:00 – Scanning for Errors 04:00 – Did the Hack Work? 05:30 – Initial Signs of Success 👀 06:30 – Testing Both Battery Packs 07:40 – First Signs of Imbalance ⚠️ 09:00 – On the Road Test Begins 10:30 – Monitoring Cell Voltage Under Load 12:00 – Is the Battery Getting Worse? 14:00 – Discharging & Recharging Cycles 16:30 – Can the BMS Fix It? 18:30 – Surprising Results 😳 21:30 – Battery Starts Balancing 23:00 – Final Charging Test 24:30 – Is It Actually Fixed? 26:00 – The Truth About the “Hack” 27:30 – Cost vs Replacement (£40k?!) 29:00 – Final Thoughts & What’s Next #MercedesEQC #EVRepair #CarHack #ElectricCar #EVBattery #CarDiagnostics Music from #InAudio: https://inaudio.org/ Track Name.Sport Rock Energetic by Infraction [No Copyright Music] / Running Faster
