FIXED! MG advised disconnection and reconnection of certain leads linked to the HV system. Went with mechanic to Fast DC charger today and it charged, much to the mechanic and my surprise. I asked the mechanic to disclose which leads were involved to pass on, but said as on HV system would not disclose and said please get mechanic from your dealership to call him to discuss. They need to speak to Steve at A E. WILCOX in Wickwar, Gloucestershire. Just one note, they also disconnected the 12 v battery which if left disconnected for more than 20 minutes can slso reset all modules. May want to try that yourself just in case but mechanic convinced it was the HV leads!
