After having installed the Wagner intercooler my fan is very loud and is running full speed, after shutting down the car i can clearly hear the fan throttling down

No limp mode, errors messages or power loss

Did a search and seems the N55 has this problem together with limp mode but my N20 is only the fan issue

What seems to be the problem

Had almost same prob. with my f30 but wasn't on from cold start, was only in very hot & when i go woot so i got a hose & waited next day when engine is cold & sprayed on fan from inside it was pretty much all dirt.. that helped a lot but only fan not engine
