2020 BMW 330e in for a hybrid fault, so we got to work and carried out diagnostics and found a battery module 5 fault. We check the live data and found cell 6 in module 5 down by 0.50 volt down on the others which is enough to shut down the hybrid system.
So we removed the battery and replaced module 5, balance the battery pack and replaced the SME module. We put the battery pack back and connected in up so A1 Remote Diagnostics could do there magic and code in the SME module. Everything back together and the car is back to how it should be.
