They changed the words they use while talking about turbo lag. See attachments for screenshots as they use Flash now...

The link to the old document still works, but it looks like they're trying to change their story.

hey guys, the brochure still says 300 pounds of torque from 1,400 rpm to 5,000 rpm !!

did you power brake your car while stopped at the light ??

if not, i am sure he did
....if i saw an audi next to me, and i wanted to play, u can be damn sure:
my foot is on the brake and i am in manual AT first gear,
DTC button is pressed at least once,
and my rpms are around 2,500+
...when that light turns green, i am outta there!

note that i have 29.2 , with it´s lag, but still can spin the tires and luanch pretty hard doing the above.

my 2 cents

It's important to realize that people may not know about this issue, or that they're not sure it's an issue. Perhaps that their dealer will deny that it's even happening, or they feel reluctant to even ask for help about it. Dealers intimidate a lot of people...

I know when I first got my car I could tell something was up - especially in parking lots or accelerating from < 2000 rpm in a high gear, but I didn't realize something could be done until I ran across this thread. Now I'm livid (yet civil) about the lag and I won't back down until either I have no lag or I have no BMW. Discounting the issue because one hasn't heard about doesn't make it not a real issue or go away.

The regional tech that was supposed to look at my car on Monday might not look at my car because of the HPFP which the dealer had to order...

Im saying I have never heard or has anyone asked me or my other SA about why His/Her 335 has a turbo lag. Im very interested in fixing everyones problems whatever they may be? I have been on the other side, and still am, and I know how I like to be treated when it comes to cars

[Quisp]

Some people may not have called it lag. THey may have referred to it as I first did....hesitation when accrelerating. I was intimidated by the dealer until I realized they didnt know it all and in some cases my then16 yr old son, knew more. The firsdt salesperson didnt know shit about the car and that surprised me since this was when they first came out and were ready to be the hot seller. He said it was a v6 turbo(as in one turbo). Then I knew i was talking to the wrong salesperson.
I called it hesitation because I believed that BMW had eliminated the lag. When I got the car it didnt have any so I would not have guessed that they would put it in for me. So i never thought of it as turbo lag.

[**335i**]

maybe somebody already from Europe or Usa has 31 version and no lags?

[Former_Boosted_IS]

Just to point out, this is not turbo lag. Turbo lag is the time it takes the turbo to spool as the car increases its exhaust gas flow enough to create positive boost. If BMW is manipulating when the wastegate opens to protect a bad design, that is a whole different thing. There is no way in the world it takes these tiny twin turbos 3000 rpms to fully spool. I think this is more of BMW giving the car a labotomy and that eliminates your claim of false advertising by BMW. I am not trying to be insensitive to you guys, but just stating a few facts.

so in other words there is no need to worry if u have v81/29.2 on your 335i

I think you completely misunderstood me. All I am is saying, that the manual stating zero lag is not inaccurate. The manual stating 300 ft.lb of torque from 1400+ rpms may very well be an issue and is easily verifiable with video on a dyno.

[Cobu]

The slow response in pull power when throttle is floored can be described as nothing else but a feeling of a lag. It could very well be though (and I suspected this for a while now) that there really is no 300lb of torque available at 1400-1500rpm w/29.2.

I will wait to see if v31 finally arrives in the US this week (according to few posts here - US delivery was 9/17 ?) and fixes the problem. If not - dyno is my next step. I really am interested to see the data.

They very easily could have just refused to update me, right?

I don't find it that hard to believe. It's like the genie in the lamp: Be careful what you wish for. You asked them to update you to v31, and they did. That it did not cure The Lag may plant doubt in your mind about what you read on the Internet. That can only be good for them, as threads like this are a thorn in their side. The more confusing/conflicting situations they create, the more obfuscated the issue, which is good for BMW.

I'm not claiming a conspiracy theory or anything here, but almost all of us have been faced with a significant amount of skepticism from BMW at all levels of customer support, and anything they can do to potentially get us our of their hair will probably be done. So no, I would not put it past them to have botched your update -- possibly intentionally -- and I am still holding out a small sliver of hope that v31 is legit.

Another couple points, since I've been silent here for a few days...


- my rattling noise is getting louder. My neighbor, who also has a BMW, noticed it as I was pulling out of my driveway. It is much worse in the first 2-3 minutes after cold start.

- to the point about newer owners not noticing -- of course this is true. The number of folks who owned pre-29.2 was finite, and now we are starting to see that so is the number of people who even test-drove pre-29.2. The guy who recently raved about his laggy dyno, and did not even know it was laggy, is proof of that.

- I worry about a class action, because I doubt it will adequately compensate us, and of course it could take years to resolve. I doubt there's any way BMW's lawyers allow them to get judged for anything more than their original warranty exposure, which might be a couple hundred bucks for each of us. I'm paying $700/mo for this car, and it's now been laggy for exactly 4 months. I'd want at least half of my lease payment back, plus compensation for extra fuel consumption and damages for giving me the run-around and wasting my time. I doubt class action will offer that. Although it is still a good thing, to prove the point, especially if any of us choose to opt out and file our own suits.

- I'll try to get some updated perspective from my dealer this week. Sounds like SA's and SF's are oblivious to the real story here, so I am not optimistic, but it'll be another data point, I guess.

I admit, I am getting discouraged about the long-term outlook here, but I recognize it's important that we early owners keep this thread alive. There are only so many of us, and it certainly does seem like BMW AG and BMWNA are trying to sweep things under the rug. If not for us, the true 335i would fall into the memory hole.

[**335i**]

so what u guys saying? if we have 29 version its very bad?

[Quisp]

If the turbos used to kick in at 1500rpm, but now dont kick in until about 3000rpm, but it isnt turbo lag, what would it be called?(not trying to be a wise-ass)Would it be remapping, hesitation, or something else?
I think that the fact that BMW is changing the way it words the description of the turbos in the 2009 model means something in regards to this problem of lag no matter what you call it.

[**335i**]

if bmw will say we do not know nothing, what then?

The turbos are 'kicked in' but the wastegates are expelling all of the boost you should be seeing. Former Boosted is spot on, BMW has detuned your car to fix a hardware problem. Realy the problem is not the turbo's but the brains that are causing the problem and could be easily fixed if BMW wanted to.

[Quisp]

Ok, I can see that it may come down to semantics by using turbo lag. As far as false advertising if the car is supposed to have the power from 1400rpm through 5000rpm but it doesnt happen until 3000rpm which is more than a 100% difference from the advertised claim, then I think that still constitutes false advertising.

This was taken from the brochure for the 2007 335I.
