Looks like its sorted , I thought I would check the connections around the ECU so removed the bulkhead trim and found about 6mm of silt / gunge in the area below the ECU , the drain was blocked and whole area looked damp , after clearing silt and unblocking drain I dried the whole area with electrical solvent .
10 minutes later all warning light went out and have not reappeared and that was 3 days ago, so hopefully
