All thanks to your help guys.

So I had a visit from an engineer, we were plugging off all indoor units one by one because he wanted to check if one of the indoors is causing the issue. But the error was always the same - 0:01

In the end he hasn't arrived at any conclusions, and kept going back to the theory that its one of indoors that could be causing the problem.

He wasn't able to say if any PCBs/fuses are blown and the fan motor wasn't checked.... in the recommendations he said that whole system, indoors + outdoor needs to be replaced.

I'd like to risk the route of fixing just the outdoor - unfortunately this model apparently is no longer produced so it'll be all down to spare parts availability....

...still waiting for the quote from the AirCon company.
