Has anyone contacted BMW regarding 29.2 and lag?

clivem2 · 09-01-2008, 04:37 AM

Something to do with a richer fuel mixture? Or maybe they left the pre v29.2 code in there for when the engine is cold (surely by mistake).

Repeated this a couple of times and the result was always the same:
Cold Engine = Power everywhere
Wam Engine = No power before 3300rpm

What gives with this????

I have the same experience!

With the V3 lagfix map you are measuring the wastegate duty cycle in order to see if you are affected by the lag - according to Shivs instruction this has to be done when the car is in normal operating temperature. This clearly shows that the car operates diffently when its cold compared to warm.

I guess BMW want to warm up the turbos?

This is interesting, I found this site where they sell the sofware update for the I-drive, I wonder if he sells the V27 for the whole system?

Do we know how the dealer updates the software? is't with a CD or do they plug in the car?

just came back to work after handing in my car for the lag fix. I'm picking it up again on wednesday.. will keep u guys posted.

note:
Got a sweet ride as a two day loaner from the sales manager.. Z4M cab!! WHAT A CAR!!!

I have heard it takes at least several hours to do a full progman update like 29.2. It would seem to be a little risky to try and update the progman
ourselves!

Cross-reference this with my observations about rattling a few weeks ago:

I received the 29.2 update a month or two ago. I've never owned a turbo car, and I didn't know what people meant by turbo lag until I got this update.

In my experience the engine takes a sec or so to develop torque anywhere under 2.5k RPM.

Let me know if there is somewhere else to sign my name. I think we need a better place to organize this effort than a 46 page thread.

I called BMWNA as well, but [B]still[B] have not heard back from them, I almost don't expect to..

i doubt if it is impossible...bmw just trying to mimize warantee claims IMHO.

best way to find out is: some one who has a car AFTER warantee has expired....then try to get the 29.2 revised back to 17.x. if there is no longer a bmw warantee, maybe bmw will let the dealer do it (i think dealer needs to get BMW permission for software revision to older versions).

note that where i am there is only a 2yr BMW warantee...but i have another 12 months to go.

my 2 cents.

dmboone25 · 09-02-2008, 09:34 AM

So I picked my car up from the dealer this weekend, after taking it in for the Lag...and of course, they have nothing to say other than "it performed perfectly, and we can detect no lag in it whatsoever."

When I pressed my SA on the issue, I got similar answers to what I have seen from other people's experiences....the biggest problem we have is that there seem to be few cars available that are pre 29.2 to compare to--that was my SA's biggest thing--all the 135/335/535s on the lot were very recent builds, thus definately 29.2. So he was like, "you know the car felt fine to me--and I drove other cars with the N54, and they felt basically the same"...so in order to get them to kind of "see" what we mean, we are going to have to do the direct side by side of a pre 29.2 car and one with 29.2////

I had requested no software updates, since I have the JB3 waiting in the wings, and I know it is good to go on the 29.2....

Manboy · 09-02-2008, 12:31 PM

I also got a message from my dealer that my car was ready to be picked up. When i get there they tell me that i had a fault code registered and showed me on their pc what they meant.
It said: performance reduction due to risk of overheating.

They removed this and went on to tell me that they could'nt fix the lag issue, and that the only thing that will fix this is V31 software.

They will be getting this sw next week and will update my car as soon as it arrives.

the technical people told me they heard of all the lag problems and they fully understand. if the V31 doesnt fix the lag we will renegotiate for a nother car or money back.

Basically guys... Its all down to V31..

slubu · 09-02-2008, 12:32 PM

Pavel, so they specifically told you V31 will fix the lag issue?

That is awesome news. I can't wait until next week to hear the results. I wonder if they are addressing the throttle response and fuel mileage also?

Interesting....I wonder if we are getting this state-side, because my dealer only mentioned the 30.whatever and the SA didn't know of anything in the pipeline beyond that.....

Their technician pretty much told me that he was'nt supposed to say anything but this is how BMW have chosen to solve the issue.
Pretty dumb if u ask me, piss a bunch of people of, deny for 5 months and then issue a fix without telling anyone??

I'll take a drive up to Stockholm on the 9th as they have the latest PC so they can just donwload it instead of waiting for a DVD..

I still have my doubts about V31.. seems to easy...

Haha, Pavel you are the man. I completely agree with your first statement. And given that, I also agree with your last. I give V31 1:50 odds that it helps.
The only thing that is mildly encouraging is the wording of your SA, how he says "this is how BMW has chosen to address this" like they somehow ARE fixing it.

I think it was discussed above, or maybe it was a different thread. V31 will be here late September for us Yanks.

Manboy · 09-02-2008, 02:47 PM

I just sent an email to BMW customer contact. They told me their technical crew would contact me shortly.. that was two and a half weeks ago.. here's what I just wrote.. ( a bit emotional but then I am a sensitive man..)

I'm still waiting for anyone to contact me???

I want to know if your latest software (V31) wich is bound to release in Europe 2008-09-09 will fix my lag issue??

Why won't BMW inform their customers about this lag issue for the N54 engine?? This is getting ridiculous!

I am selling my vehicle next week if the sw V31 does'nt solve my problems. I know several other owners that will do the same!

Please revert!

What do u think.. to much?

midlife · 09-02-2008, 03:05 PM

hey guys,

joining this thread very late, so do not flame me (i have been away from this forum for last 2 months modding an e36).

...very anxious to hear about the new v31 results, but what happened with the v30 software?....no help i guess??

thanks
