E60 Swirl Flap size anyone ?

Recommended Posts

Hi My vehicle is in with an Indie and he is changing glowplug controller which requires the inlet to be whipped off,  so as a preventative measure I asked  him to check out condition of swirl flaps (the cars only covered 80k mls he's confident being a later model equipped with the stronger spindle type and low mileage it shouldn't be deteriorated)

However in the event they are  I want to know the size fittedto mine. I have an M57TU D25 engine, the vehicle is a 525d Msport on a 56' reg production date Jan 2007, what size swirl flaps is it likely to have ?

is it true that pre 2004 had 22mm and 2004-2005 could have had either and 2006 onwards were fitted with 32mm ? 

I know the only way to be sure is to check but to save time because the Indie is so busy and would need parts at hand, I wanted to be forearmed with replacement part especially as they're only available online and can't be picked up from a parts store,

^+1 for what Dotcom says. You could check by entering your Vin into realoem.com to see if you have the flap free manifold but if the manifold is coming off anyway I guess it doesn't matter as you'll know soon enough.

My 56 plate 330d had the larger swirl flaps. I believe they are less prone to failure than the older ones but for absolute peace of mind get them out. There are no negatives to this that I can tell and it’s not too bad a job to do.

Yeah OP yours will have the larger ones for sure.

 

The larger ones are still metal but with an orange plastic tip around the perimeter of the flap. This orange tip does start to crumble and go bad.

 

The swirl flaps have been removed on mine and on an X3 I owned a few years ago. It's a no brainer modification in my eyes when you consider what could happen if one or more fails.

Thanx for replies, The Indy said he'd thoroughly check the condition of them before recommending blanking plates.  He sounded pretty confident because he has been a specialist over the last three decades, that they wouldnt be prone to failure, he's seen them deteriorate on the earlier types but never in the post 2006.

Ive been lucky in the past owning two E39 530d sports one had 190k the other 130k both of which I had clicked most often mileage and was fortunate never to have them fail on me.

As Wakey says, 'when you consider what could happen if one or more fails'.....

Your Indy may be right but you don't want a failure on your car to be the first one he's ever seen.

It went in for the glow plug module replacement and whilst the inlet was off I had all gaskets and blanking plates fitted. The original flaps were actually in really good nick and weren’t heavily crudded gaskets too, but thats probably down being a low miler and to fitting a new EGR and Engine Carbon Clean last year. 

 

So took above advice and preemptively replaced so jobs a good one !
