With little responce to this question i was intrigued to find out if mine had them as i try to do as much maintenance that i can manage myself to try and avoid hefty repair bills with these cars being pretty expensive to repair....especially at dealer labour charges


I did a fair bit of digging/web searching as AW8 did but couldn't find a definitive answer.I also checked real oem and took of the engine cover to check for the actuater bar that operates the flaps.
At this point i was 99.9% sure that i didn't have them.Also a few knowledgable folk on here like bazzyboy etc had said that they do not exist on x5's which made me even more confident that they were'nt on my model/year.
Well now i can also fully confirm that i don't have swirl flaps (2004 54 plate aug build)as yeaterday i had to remove the inlet manifold to do another job and to my delight there were no swirl flaps present.
I know that this has been gone over on several occasions on here and some peeps already know about there own cars but i thought i would post up about my year/model for the benefit of other 'non mechanics' who have the same date car that are still unsure.
Here's a pic to show no flaps
