Default I am probably going to get shot for this...but Swirl Flaps - once and for all.....

Hi All

I know there are many other posts about this subject on this and other forums, however, I am yet to find a post that answers the following question.....

Rather than people stating their opinnion or their view on the risk of potential failure and with specific reference to the 2006+ 535d engine (pre-LCi but improved swirl flap design)...... Has anyone got specific examples of failures of swirl flaps in this specific engine?

This will help me with my sleeping... specific examples appreciated only please....

a simple google search will show you many cases of failure. even pictures of failures.

That example looks like the older design? My understanding is that around March 2006 the design became a plastic type? Have there been any specific examples of these failing?

ah ok. according to this thread, there havent been any reported issues.

BMW diesel engine "SWIRL FLAPS" all you ever ever need to know about Swirl flaps!

the last of the swirl flap engined cars had swirlflaps manufactured fully in plastic so any engine ingestion damage would be minimal but as of yet no decent data is around on this type of ingestion and personally i wouldnt want any sort of plastic either flying around inside a cylinder bore which could end up exiting into the turbo area...
