I did the coolant pipe hose and the first time I start the car up it has an engine light and a rough idle and I don’t know what possibly it could be

 

Double check everything you touched in the pipe replacement, especially the sensors and electrical connectors to those sensors. Also when the engine is running can you hear any hissing? Hissing would indicate a vacuum leak.

 

yeah it’s sound like it’s whining when I rev it

 

Which hose did you change? And what year and model Macan?
