I'm not sure if it is original, it is the first time I work with the type of engine. However, it looks original and fits well with the diagrams.

ECU number is 4A0 907 557 A - Do you know if there are immobilizer on these? Because, I get spark at the spark plugs but no fuel through the nozzles. That's when I used it the diagram, and grounded all the right wires also given power to where stated.

I believe it's just a small error, which makes it not start.....
