Are BMW swirl flaps a problem?

Hello I would like to know if swirl flaps are a problem in BMW cars please. I would also like to know at what stage should you look out for this.

Thanks.

Hi Declan,

I must admit that it wasn't a problem that I was aware of up until now, but there is quite a lot of literature about it on the internet. Here is a forum thread on the topic.

We also found a website that offers a cheap solution although we cannot verify its effectiveness. We will find out how bad the probem is in Ireland.  

It would seem to be that there is no real way of checking for this in advance because it doesn't appear to be on the service check list, though we do know that an improvement was put in place post-2004.
