In the history of evilution, I had never had to remove an engine. Just my luck I had to start on the hardest one. Even then, I wouldn’t go as far as saying it was hard, just time consuming, awkward and daunting. Including taking photos and notes, I achieved this in about 3 hours. I was in no rush and didn’t have a guide.

DISCONNECT THE BATTERY EARTH LEAD.
Remove the rear panels, jack the car up and remove the 3x 10mm plastic nuts in the arch liners.

This reveals the ECU. There are sliders on the electrical connectors. Slide the top one up and the bottom one down.

Then the connections will pull out of the ECU.

The top and bottom connectors are separate looms. You only need the bottom one.

At the base of the loom is another connector to disconnect.
