Will a Remap Compromise my Swirl Flaps?

Emissions reasons.

Where did I mention swirl flaps in the post you quoted?
I said, boost pressure increase through the turbo unit, No?
I also did not know this was the case. No need to be unpolite
Then don't post crap.

Emissions - you will produce more CO2s. If you care, plant a single tree and you will more than negate the effect
.No loss of performance, no extra noise, no extra heat.
For reference, my 330d (manual) doesn't have swirlflaps, the 330d auto does - PURELY to reduce emissions.
Oh I see, so you've been proved wrong about those so you moved onto something else to try and get a bashing in. Sigh
Didnt realise.Turbocharger failiure is something which blights virtually every (infact perhaps every?) commonrail turbodiesel. The 320d is no worse than anything else in this regard, I dont think there is a single marque which isn't known for blowing turbos.
The swirlflaps are the huge 320d issue, not turbos. Turbos go, but they go on every TD.
Buy diesel - over 4 years you'll save enough in fuel to buy a new turbo
Yup - it's legal.
Will still pass MOT emissions. They are there to reduce CO2 emissions - only important for company car ratings.

I don't profess to know a lot about the swirlflap issue. But I know that the turbo units are weak, a quick Google backs this up with numerous horror stories. You read my post incorrectly and thought I was still referring to swirl flaps. This was obviously not the case.
So instead of watching you BMW boys come in and tell him it will be OK I preferred to bring up the point about the increased boost with the remap just so Easy understands what it is he is getting into. I don't want to see him get burnt.
Which WILL put more pressure on the unit and thus increase the chances of failure.
You just read my post wrong
Nick I'll be happily corrected if I'm wrong, but no need to be rude about it you angry young fellow.
NickXX you seem to know more about BMW's than [TW]Fox
Why do people worry then?
Why doesn't every enthusiast remove them?

And of course private car taxation as well - which remapping wont affect, but remapping wont effect company car ratings either.
Mostly due to the fact that it involves getting your hands dirty. Didn't matter when they were in the 3 yr warranty, and it has only recently started to emerge as a major problem - I guess because the age of the plastics mean that it has started to get brittle. A fair few members on BMWland have professed to now being swirlflap free - and there are guides on how to do it.

Then stop pretending you do.
Oh do shut up, complete hater
Notice how you didn't make him aware of the increased boost with the remap. I did, no point saying it's ok everything is fine when it may not be, increased boost with the remap could shorten the life of the already weak turbo unit even more so.
I'm just trying to make Easy aware of some of the issues which could be amplified, hey OK I was wrong with the swirlflaps but these should be removed in any case. Putting them on just to get into a tax band knowing fine well they could fail down the line is a bit :/
Actually to be fair I doubt BMW expected them to fail that would be daft.
From BMWland
"A couple of days ago while my car was in for service with the friendly local indie specialist I asked them to remove the flaps from the manifold at my risk. They were happy to do that having done the job several times now. I had a replacement engine 10K miles ago but decided that the risk was one that I don't want to take again so the flaps have now gone. The indie said that they thought the car was a little more 'responsive' which is what others have reported. I've driven it for two days and think that is the case though it is not a huge difference. One difference is that at low speed one can now hear more turbo noise - the flaps must have been masking that previously. So I now look forward to trouble-free motoring....."
Think I may get a flap removal...

It's like a 12-15% increase on peak boost for most of the standard remaps. Diesel remaps increase fueling and barely touch on turbo boost - I.e. the additional wear on the turbo is negligible.
BMW put them in as they reduced CO2 emissions, they wouldn't have put them in if they realised they would cause catastrophic engine failure. It's pretty obvious now that they should be removed now, but a remap will make no difference whatsoever on their longevity.
Leave this thread now, you have proved your ignorance on the matter.
Once again you have reinforced your utter contempt of the 3-series BMW, offering nothing useful to the discussion.
What has my supposed contempt of the 3 series got to do with my advice on a remap. Which is proved to put extra wear on components. Everyone knows this.
OK so a 12-15% increase on the boost on an already seem stupidly weak (yes it really does seem that bad from what I've read) turbo could amplify turbo wear even more. It's pretty much fact a turbo would fail on a remapped car faster than it would on a non remapped car.
You know what would be nice. Instead of you attacking me be it personally as it was last time or calling my posts crap would be to offer a friendly explanation and point out where I'm wrong. I'm happy to work on my ignorance. You just seem to want to insult me. I'll remain cool about it if even just to annoy you . The only thing messing up these types of threads is your hating towards me.
If you do still have a personal problem with me please add me to MSN and we can discuss this and perhaps resolve it.

Have emailed simon mate.
Thanks for the link.
Cool - he'll be a lot better at explaining it than me anyway.

Lol, I'm not the one who's lost my temper
The boost difference on a run of the mill turbo diesel remap is so small that is doesn't make any real-world reliability difference. If you can dig up a credible source of where the opposite is true, I'll happily eat my hat.
I've not personally attacked you, I've just derided you incorrect statements.
I deem this fair, for the reasons mentioned in my earlier posts
But the unit is already known for bad reliability as it's pretty weak. Surely the smallest boost increase would be amplified. This seems logical to me?
Maybe not in this thread...
