Noise from engine bay/front grill

Krabbypatty · 02-14-2021, 12:06 PM

Hi all,

I got a M340i and when the car is started it constantly makes a noise from the front of the car near the grille. Sounds like an electric mechanical noise as if something is constantly opening or closing. Happens about every 30 seconds to a minute. Haven't experienced this before. I will try upload a video of it soon.

Anyone had an similar experiences?

alot of the bmws have whats called Active Kidney Grills and they open and close based on if the engine is needing air or not

there could be something wrong with it. bring it to a BMW dealership and have service take a look at it and it should be covered under warranty
