Has anyone come accross this prob before, had flat battery on my vrs the other day , after jump startin i have no leccy windows, interior light, courtesy lights on door and key doesn't lock or open doors, have checked all fuses seem to be fine.

They all have one thing in common, the convienience ECU.

Have you managed to establish the cause of the flat battery?

Try disconnecting the battery for a few minutes to see if it will reset it.
