Yup, swirl flaps. They either become detached from the individual rods in each intake, or the actuating arm gets disconnected through wear - There are kits available to delete them permanently.
Thanks for the info it’s not even a month out of warranty it has poroblems with the sat nav and cruise control as well expecting alot of goodwill from BMW
Hi jabber
Did u get that resolved? I got the same problem. My f46 2 series drives fine and no MIL light on the dash. Its auto startstop was not working and u just ran obd scan and it threw 279100 and 279000 codes. Not sure if it has anything to do with startstop but now I can't get this out of my head
