QUESTION: Yes the original engine code was AEB and the replacement was also AEB.

Answer
If all the wiring was hooked up properly then the car should be ok.If the harness is exactly the same, i do not know why the lights dont come on.Did you make sure the engine was the same series as some vw parts will not work in other vws.I had a problem with this for a tps sensor which caused a high idle until i got the proper series.You may need to have your on board computer reflashed.The whistle noise could be a vacuum leak.
