You need to remove them ASAP. Its a design flaw on BMW and a bomb waiting to go off. Plan a nice weekend and remove those suckers. If you dont have a DIY here it is.

took apart this sht today and noticed i dont have those flaps and then found this: " M47 engine(136bhp non common rail vp44 injection pump) DO NOT HAVE swirl flaps

M47N common rail engine (including M47N/M47TU/M47TUD20)(150bhp face lift model August-September 2001 onwards) has flaps

M57 engines(M57D)(525d & 187bhp 330d) have no swirl flaps on the manual cars BUT AUTOMATICS DO"

well i guess im one of the lucky ones who dont have these flaps
