I changed the mains cable to the original continental one (with an adaptor) and it went away for about an hour.
No its back, but a lot quieter. Just a varying 'rumbling' sound like a distant storm. Very audible when no music is playing.
Could it be something to do with the mains?
May be a loose mains connetion inside the sub at the IEC or on the mainboard. If you know how to do it you should open the unpowered back panel and have a look on the connections inside. It could be a very simple issue. Post a photo if you're not sure.
