Crash Data LOCKED This EV… But We Found a Way to Bring It Back!

A Vauxhall Combo Electric van arrived at our workshop after an accident — completely unable to drive, full of warning lights, and diagnosed by others as a total loss. But the truth was FAR more complicated… and far more interesting. In this video, we uncover hidden crash data, a battery control unit that refuses to reset, and a transmission that wouldn't come out of Park. What started as a “simple” EV fault turned into one of the most technically challenging repairs we’ve done on a Stellantis-based electric vehicle. From dropping the entire high-voltage battery pack, dismantling the BMS, discovering why the reset function NEVER works on these models, replacing a nearly £1,000 control unit, repairing the transmission parking actuator, and finally getting READY mode back… 👉 We saved this EV from being scrapped. If you want to understand real EV diagnostics, crash data logic, BMS behaviour, and the hidden complexity behind Stellantis electric vans — this video is a must-watch. 📍 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 📲 Follow the Behind-the-Scenes Garage Life: 🎵 TikTok: https://www.tiktok.com/@ogsmechanics 📸 Instagram: https://www.instagram.com/ogs_mechanics 📘 Facebook: https://www.facebook.com/share/15J54KFwjE/?mibextid=wwXIfr ⏱ TIMESTAMPS 00:00 – The strange case of the “dead” Combo EV 00:40 – First warnings on the dash 01:30 – Dealer tool vs aftermarket tool 02:55 – Crash data that REFUSES to clear 04:40 – Decision to remove the high-voltage battery 06:30 – The most bizarre brake line design we’ve ever seen 08:15 – Opening the HV battery & checking the BMS 10:00 – Why the reset function NEVER works on these vehicles 12:40 – Replacing the Battery Control Unit (BMS) 14:20 – Installing the pack back into the van 16:00 – Programming with DiagBox 17:45 – READY mode… or maybe not? 18:30 – Parking actuator failure 20:15 – New actuator install & programming 22:00 – The first successful drive 23:00 – Full cost breakdown 24:10 – Final thoughts & EV repair realities #VauxhallCombo #ComboEV #ElectricVan #StellantisEV #EVRepair #BMSFault #CrashData #HighVoltageBattery #EVNotStarting #OGSMechanics #EVDiagnostics #BatteryControlUnit #PSAGroup #ElectricVehicleRepair #TechRepair Music from #InAudio: https://inaudio.org/ Track Name.Sport Rock Energetic by Infraction [No Copyright Music] / Running Faster Music from #InAudio: https://inaudio.org/ Track Name.Sport Trap Rock Workout by Infraction [No Copyright Music] / Are You Ready
