I just wanted to put an update here to the issue. What started as an intermittent millisecond power loss and then a no start, no crank is now resolved. I didn't have a negative switch to the main relay under bonnet. Traced the negative switch from Black and grey wire 4th pin as shown with led leg, this goes to the large connector on ECU. The other end is under main fuse board under bonnet.There was two brakes in cable, I re soldered and taped the connections and fixed the issue. Hope this helps anyone else with similar issue.

Hi. I've changed the relay and it made no difference. I bypass it by removing the relay and taking a live feed from + battery direct to the socket that the relay was in.

Hi all. I have been looking at your posts and thought I would share an issue I have. I have a Skoda Octavia Vrs 2011 diesel with 42k miles on clock. The other day I went to it and it wouldn't start. It doesn't crank just beeps and nothing else. When I bypass the relay under bonnet it starts and drives. Image of relay attached. Has anyone had this issue and managed to trace the issue?
