Ecu plugged had suffered heavy water damage, I wouldnt know where to begin with testing the wiring for shorts further up the loom.
Old ecu would not allow the throttle body alignment. Assume drivers damaged due to water damage.
New ecu adapted, TBA completed, no error codes stored with VCDS.
Battery voltage good, spark good.
If the engine is flooded it would start today. Another way to start a flooded engine is remove all leads and push them on so they only just touch the plugs but dont clip on them. (not sure why this works).
Also try removing cam belt cover to check cams turn when cranking.
I suspect there is another damaged sensor/actuator caused by the water.
Im sorry I dont know enough about petrol engine management to help you further
Here are the extracts from the initial VCDS log, all codes were cleared, even after failing to start, but as i said, somethine may come back when it starts, feel free to pop round on the way to work.
