Ecu power relay location!? 2007 1.8T cupra

[Danicupra8]

I have a 2007 ibiza cupra 1.8T I’ve plugged it in as having starting trouble and it’s coming up with code - p0685 ECU power relay.
Does anyone no which relay this is!? And where it’s located? I’m very stuck trying to replace it but I don’t even no which one it is and parts companies are asking me which number I’m looking for!? HELP!!!

Hi mate check the blade fuses on top on the battery to see if any of them are cracked. They are flat bits of metal about 3cm long.
