I know some of you confirmed this in 29.2, so you already know what I'm talking about.

No.

I have a 12/06 build 335 never been updated before had the wastegate issue appear recently so they upgraded the car to v32.1 and let me tell you its garbage!! I can't understand how anybody could have anything good to say about this so called fix for turbo lag??? My car now has no balls under 3 grand and it was very easy to notice the first time i drove it after getting it back. O yeah its been less than 2 weeks and less than 1000 miles and wastegates are now making that same noise again , i can't believe they did this to my car ITS BULLSHIT!!!

[BMWagain]

Then maybe I should hope to get v.32.2.
I got MSD81 that supposed to be unaffected by lag.And the new 32.1 is meant for MSD80.

[Jbabl]

So far mine does not seem to have any issues, built 04/07
I'm taking it for the oil change tomorrow, and thought of asking them to check wastegates for any issues-or maybe I should just leave it alone for now?
I might do the rev up to 4000 and listen for rattling, haven't noticed anything before
Should I take a software upgrade if they offer it?
Why didn't they just adjust the actuators in the first place if there was a problem(?)

Thanks for any extra info

[tooch]

trust me if you don't have lag don't get v32.1 you will not be happy. my wastegates make vibration @ about 800-900 rpm and then again at 1600 i haven't tried to listen at higher rpms but if i have to listen to these noises then i'd rather go back to my old software. Its highly noticable the decrease in power,and it doesn't even fix the problem. i wish i would of never even complained about the noise now.

[tooch]

Hey Iscream did the wastegate conversion fix the lag or not? or does anybody know if this conversion option is an actual fix for the lag at lower rpms? thanks

I was a bit cryptic one page ago, but my impression is that 32.1 "with conversion" is not discernibly better than 32.1 without conversion.

HOWEVER, the conversion is supposed to restore the "original" wastegate behavior. Given that I am sure that at least one wastegate is opening at 3300 RPM, then I know this to be untrue. So, either the conversion is not the original program, or my particular conversion got botched, or there is some other problem with my car... which is why I asked the question above.

I got tired of dealing with this, like 5 months ago.....

Tooch -

You mention the 'wastegate issue'. What does that mean rattling? You need to be more clear on the symptoms before you went in and what you're hearing now.

If you complained of rattling, they gave you lag to fix the noise. You need to insist on actuator replacement and the software lag fix

Yes - it fixed my lag.

Tschuss - thanks for your help so far. Also don't forget that big piles of shit attract flies, too, and that's what some of us have been working with, whether we like it or not.

BTW, do you hear your wastegate opening on decel?

You need to turn that chicken shit into chicken salad! Seriously, if you cannot get your service dept personnel to respond to friendly/cooperative behavior, then it's time to find another dealer.

I'll let you know what I find out on the decel. Not sure why it matters though.

I have the wastegate conversion documented and yes, I hear a metallic click at 3300 rpm. I do not remember this click with < 29.2, but it was present with 2.32.1 with the "rattle fix". I believe the January Service Roundtable mentions something about this.

But, then again, now my wastegates rattle all the time just like they did when I took delivery. They did not rattle when I had that 2.32.1 without "rattle fix", which I had for about 3 weeks.

2 weeks into the conversion, the car is night and day vs. the non-rattly 2.32.1.

Its at the dealer now and i asked for the new 32 software update. They are using the new ISTA system and are having problems DL software. So they are keeping the car until Monday so they can figure out what's wrong. The SA mentioned something about iSTA reporting that the software DL was not effective? Have you heard of something like this?

Ok got my car back after two days at dealer. I was told that they DL v32,using ISTA/P, but did not get confirmation on the conversion part of it. So they need to regroup with BMW and get back to me. Anyway, I have to say that I definitely feel like the torque curve has been lowered, seems like power starts almost exactly at 1500 rpms. The car seems exceptionally quick???? So next step is to go back to dealer once they understand how to operate and DL using ISTA/P. I wonder if I could actually have the full software DL, but the ISTA/P is just not reporting it??

Strange, then, how it is not present on pre-29.2 and some retrofits, but is present on others. I am wondering, if the wastegates open at any point above 1400 RPM, then how can it be the same as the original programming? I'd like to hear some more responses on the deceleration tick vs lag.

BTW, Bill, I've been cordial and assertive with the people I've dealt with, only coming close to the boiling point once with BMWNA customer service. The trouble is, even when they TRY to help you, they are not always enabled, and that is as frustrating as anything else. You'd think for a global corporation that relies so much on advanced technology to keep its customers safe, they'd be better at internally educating their employees on these things.

Does anyone know the best way to quantitatively compare the lag in two cars? I think I know someone who still has a pre-29.2 (and no tick) and would like to compare the retrofit with it.

[Quisp]

iScream, I think that if dynos were done, back to back so conditions were identical for both cars, you might be able to compare. The cars would have to be run in the same manner for both tests. You could then compare the curves and see at what RPM each car spiked.
Just an idea, not sure if it is what you are looking for though.

Got my update today. Exact version unkown, but I know that ISTA/P 2.32.2.0.1 is out and assume that's it.

In my case, the menu item under "retrofit" was not available. This is an indication that my car got the "lag-fix" per default. Maybe ISTA/P includes a production database... however, my foreman told me that this option is not available for MSD81 cars (mine is MSD80).

Car is back to normal, although the difference to v31.1 is marginal. More wheelspin at low RPMs, especially today when we had 10" of snow in Munich.

I'll call that topic a day.

Thanks everyone. Great work, folks!

I know how to access the hidden menus in iDrive, but once in there what submenu shows if you have received ISTA/P 2.32.2.0.1 software version?

iScream - I've done your requested test. As the rpm's fall from 4k, I do not hear any clicking or any other noise that would be wastegates closing.

Fortunately, my 135i has a problem recently documented by BMW, and a software update via ISTA/P 2.32.1 or later is necessary to fix this issue (TSB: http://www.1addicts.com/forums/showp...&postcount=169). It's a relatively minor issue to me, and I'm in no hurry to have it fixed. However, the lag is a much bigger issue in my book, and it would be tremendous to receive an update that will address this lag appropriately.

I've gathered in this thread so far that 32.1 seems to be the fix for those with MSD80 or pre-29.2, but there doesn't seem to be much discussion about the real value of 32.1 for cars with MSD81. This is the reason for my hesitation, and it doesn't help to know that shaddai, who received the 32.1 update for his MSD81 car, stated that there is still a disappointing amount of lag. (Hopefully, it's just his fuel pump )

But on the other hand, there's meyergru who I think mentioned the chance that the lag-fix may not even be available in a subsequent update.

So considering it's a one-time shot because dealers will not provide an update unless there's a "valid" problem that requires it, here's the question:

Take it in now and get 32.1, or wait for a later revision with a possibly better lag-fix?

Advice would be appreciated...especially from "mentors" meyergru, ezatnova, iscream, shaddai, or others...

While I hope it's just my fuel pump, I severely doubt it. As far as I'm concerned, the fact that BMW gave me a cash settlement in compensation for turbo lag on an MSD81 equipped car (they have my VIN, obviously) should be enough information for anyone.

I still have yet to meet up with the MSD80 never-been-flashed 335i in my neighborhood... I do expect to be disappointed, unfortunately.

As for the update, should you get it? That depends on whether or not you expect it to fix anything. If yes, then go ahead. Will it fix any lag you have? Doubtful, but it might make a small difference. My car was hellbound on driving me insane the first few days (especially intermixed with long cranks). I think it's settled pretty good, but it is still not like what BMW advertises.

[tooch]

My SA called today and said BMW agreed to change the wastegate housing on both chargers also said they are going to reflash my car back to original??? Is this possible? Maybe I've only had v32.1 w/so called conversion update to my software. word is they can only go back to the previous version that was on the car which in my case is back to the way it came from factory (when it felt like a rocket). kinda caught me outta leftfeild i figured they would attempt to change acuators first. In SI B11 13 07 i don't see any procedures that say replace wastegate housing so hopefully they've come up with a new and right way to fix this problem.
