Exclamation Swirl Flaps

Its not a euphemism, don't worry, I was just wondering if the notorious swirl flap issue of older 30d's was still present in the current N57's - such as mine. I know the first gen X5 30d was prone to this issue and the symptom was unsteady idle at start up. Do the current 3.0L's suffer from this?
I'm wondering because it was brought to my attention after watching a (shite) Fifth Gear review of buying a used X5 30d and it was recommending you watch out for this as it can lead to dramatic engine problems.
This brings me onto another question; is my car normal? On 8/10 (evening through to morning - 13hrs) cold starts, the rpm at idle is ever so slightly fluttery until it warms slightly. Is this normal? The current temperatures at cold start are about 2 - 6 Degrees C so rather cold but I don't remember it doing this before.

I don't think this affects the US 335d. I believe I remember someone asking this on another forum, but I don't remember which one. I'll try searching for it.

Try looking on REALOEM.COM to see if your intake has this feature.

U.S./Cdn-spec M57's have swirl flaps, but they are electrically actuated (vice the vacuum actuation from earlier M57's). (Ref: the ST810 Advanced Diesel presentation)

I believe our engines are still prone to this fault but not as likely to happen as it used to do.

Had the same symptoms on my 330d E90 LCI.

Slight variations at idle on first morning startup. If you press the acelerator a couple of times and bring the RPMs above 1000, problem would not return until next morning startup.

It was a problem with the swirl flaps and it cost me over £600 - BMW only sells the whole intake set.

I wonder why they come up with one diesel engine after another and they all seem to have this problem...

Exactly the same symptoms for me but it turned out to be my glow plug control unit.

That's what I thought my problem was too... Either a glow plug or the control unit.

Anyway, I'm removing my swirl flaps in the next few days. Shouldn't cost me more than £50 for the job and it's the only guarantee that it won't happen again.

Just for the record, it's a European 2009 E90 LCI 330d Steptronic.

My 330d is still ever so slightly unsteady at cold start and ONLY stone cold start for 30 seconds or so, until it is revved.
Mine is also a 2009 but a 6MT. 80k miles on it now.

Swirl flap failed 4/12 on 2011 335d

My dealer diagnosed a fault (service engine soon lite) as a swirl failure.
Had to order a new air intake from the motherland, fly it here and replace
it.
Car is a 2011 335d bone stock with 3,500 miles on it.

It ran fine, the light went out a few times, kept coming back, so I took it to the dealer.

8,000 miles and a cross country high speed, high temp (west Texas ) round trip
From Phoenix to Ft. Walton Beach, FL

Had a loded pistol just in case

I just brought mine to the dealer for a yellow SES light, same issue as ithatel mentioned above. Stock everything, exactly 7k on the odo. The SA said he has to order a new part to replace the swirl flap/manifold.

They found fault code #4B67(I think?) and ended up installing a whole new intake manifold. I think they reset the ECU too, because my mileage has been crap since them (~33 before, down to 27 now)

Hi Guys
I have resently had my intake manifold replaced before the swirl flaps would be a problem. And yes the swirl flaps is controlled by vacuum in europe and cannot be replaced seperatly, only by replacing the entire intake manifold.
There are some solutions in the UK to remove the swirl flaps. The ppl I have read about cannot feel any difference before and after removal. As far as I know theres no coding involved in removing the swirl-flaps.

The new intake manifold is a bit different than the old one. The axel where the flaps is mounted is stronger, the swirlflaps is mounted with small screws and the actual flap is covered with a rubber band at the edges. Proberbly to keep it sealed and to remove any debree building up inside the intake manifold.

Hi guys,

do you have any updates if swirl flaps can fail in N57 engines and destroy engine? it happens in M57 but what with newer engine? I've been told that intake manifold is designed to prevent the M57's issue.

thanks.

I had a "swirl flap actuator" fault code due to carbon build up and they replaced my entire air intake manifold under warranty.

yeah, I've heard about some issues, but I just was wondering if the flap can damage an engine when it fails.

On the newer engines the actuator can still fail, but that is not the same as an older failure. On the older swirl flap design the flap could come loose and actually fly down the intake and possibly make it into the cylinder causing serious issues. This hasn't happened on the updated version that I know of. Also, at least for the US version most of the actuator failures are probably due to carbon buildup so you don't need a new intake, you just need to clean up the flaps and rod

I have an error: 4E0F DDE Swirl flaps, plausibility and I'm not sure if I just should clean intake manifold or replace it?

Thanks.
