Now I did not say your dealership screwed up the install - maybe they did it right, maybe they didn't. What I have suggested is that you verify with them that the vacuum line machine they use to setup the actuators is calibrated correctly, as my experience with machines here in the UK suggest that the majority of them (at least in the UK) were NOT calibrated correctly. Even the machine at BMW UK was out of calibration, and we had a delay in waiting for a new machine to be shipped from BMW Germany.



I understand your position regarding your dealer, and I sympathise. With regards to the PUMA number, I will obtain the details tomorrow and PM you. Be aware that as I have already said, this PUMA refers to the "Clanking sound from the engine" and not specifically turbo lag, although obviously the turbo lag is a direct result of the "clanking sound", which has been attributed to faulty wastegate actuators...!

BMWNA, or your dealer, should contact Philip Neal, Regional Technical Director, at BMW UK (+44 1344 426565) who will be able to confirm the vacuum line machine calibration issue.

I wish you the best of luck!


To everyone else..

I have provided the information in my posts so that it might help you US members find some resolution to the problems that you have been facing. I have had numerous problems with my car, mostly engine related, and through a long process of investigation and repair, including having the engine out, those issues have been resolved fully. In no particular order, I have had fuel pump replaced, new ignition coils and a complete set of injectors, new turbos, new actuators and wastegates, new ECU...

I have been as angry as you appear to be, and I took a proactive approach in trying to find a fix, involving people from BMW Germany (who flew over to see me) and BMW UK. We found the fix for all the different problems, and applied those remedies to other cars that had similar issues.

Now whether some of you consider my posts to be implausible facts or not is entirely down to you - I don't find the need to justify any of the posts that I make, as I make them to be helpful and not for any other reason.

I find it amazing that having posted my own findings, which I don't force upon anybody else, that I get a barrage of critical PMs accusing me firstly of working for BMW directly, or as one member suggested, making up a solution so that it would shut everybody up.

You can all take the information how you like, it doesn't really matter. However, I will not be posting any more information up here because I am sick to death of the trolls and haters on this forum that have nothing better to do than to criticise and accuse. For those genuine people who want help, PM me and I will do what I can. Otherwise, keep trolling...
Please ignore idiots, we are a big bunch of people who appreciate you posts

E92fan, sorry you had to deal with many idiots, This is not Europe as you know. I know for a fact you are on the right track. This makes complete sense with what a friend in BMW told me: That they were increasing vacumm pressures to addres the problem. thank you for taking the time to write such well inform posts, see you in the UK forum..............

Im guessing you have the bolded.

Do you feel poor throttle response in the low revs?

What might E89X-08-09-520 stand for? Car is manufactured in september 30 2008.

Thx alot.

E92fan...Its time for one of the "original six" to chime in and give my 2c...I am thrilled that BMW on the other side of the pond looks serve you Beluga caviar with your service visits. As us on this side of the pond cant even get our SM's to piss on us when we are on fire. If your problem is solved and you are happy, more power to you and I thank you for all the info, but, as been said a few posts ago and I tend to agree, I find it troubling that your BMW dealer practically gave you a whole new car in parts and we cant even get a new spark plug wire. The info you gave us sure sounds logical and rather simple to apply. With that being said I wonder why it is so difficult for the US dealers to apply what you have givin us? I do remember the BMW engineer who went with me for a ride saying that the European software versions were completely different than the US versions with emissions and safety (yes he really said safety) and that the ecu software version numbers were different than the US versions. I now know this is not true as with alot of what he spewed.
Trust me when I say that I would love to sprint over to my dealer and give him the info you just gave us and have him tell me " come on down and we will have it fixed in a jiffy", but, I have a feeling I have a better chance of getting the same old story of ancient civilizations of southeast Asia.

I couldn't have said this any better. I need to hold off until there is a DME update and as far as we all know there is no such update associated with v31. If I were to try and go to my dealership and tell them their machines are not calibrated correctly and they need to have them replaced it would not get me anywhere. As many have mentioned already I really appreciate your input E92 and please continue to supply us with as much informative material as you can but it is a different game here in the US. I wrote my SM last night and I will post later and tell you what he said but I guarantee it will not be promising.

Also, can you (E92) provide us with some more information on the PUMA case. If there is a number associated with it so I can reference that to my dealer.

Welcome to lag/virus/29.2+ hell. Imagine how much more you'd love the car if it sounded and performed as it should!

I don't understand what's going on. There are several reports that BMW NA understands that there is a lag issue, and is working on a fix. Then there are reports that BMW states that is how its supposed to drive from now on.

What's the real answer here? Does anyone really know the answer, beside just making conjectures?

Hitting the gas at 2000 rpm gives instant response.
What the guys with v.29.2 have been writing here is there is no go under 3000 rpm. Another truth is that BMW never had 400nm torque at 1300 rpm. It reaches 400nm at 3200
Itīs 150nm at 1300 rpm.

The reason there is only conjecture is because BMW is doing a great job of lying and keeping everyone confused. That and the occasional carrot in the form of 'a fix will be out in __weeks' seems to be BMW's way of dealing with the problem. BMW is the most dishonest company I have ever dealt with.

I took the wifes xi to work today to have a dent fixed, PDR. She has a pre 29.2, I could tell a very big difference with low end torque, mine recently got the 29.2. I left her car in drive and tested it, and then tried DS, and manual shifting. To me, when having her car in D, it was like having mine in DS mode. Mine just feels so flat until it hits 3000 rpm, I find myself using DS mode all the time, just to get the car moving.

How stupid is this
BMW pretends they are unaware of their new software detuning our cars.

So it takes an aftermarket tuner to fix it

BMW sucks.

Vishnu Rocks- from their new Plug and Play-
http://www.vishnutuning.com/V3PNPRace.htm
Lag Fix
This parameter enables a “fix” for those owners who have been undated with an unfortunate software version at the dealership. This version has been shown to reduce turbo boost response below 4000rpm. When this parameter is enabled, an alternate duty cycle map is activated in the PROcede- one specifically designed to eliminate the lag caused by the aforementioned software update. Do not activate this feature unless you have this lag-inducing software version. Doing so may result in a trouble code/limp mode.

I went to BMW of Valencia today for a software-retrofit on my 335i coupe to activate the alarm and they did a complete software update.... I asked specifically about the 29.2 and told them i didn't want any negative effects. if thats what i was getting i didnt want it.
I was told that the latest version v31.1 is good . i'm a truster, so i went for it. i bought my car at the beginning of August and my guess i was post v.29.2 but pre anything near v.31.1..... as my car drives differently now after the update. feels to me like there is more low end power and with a smoother delivery. I am happy. tho i have not "nailed it yet". Hope i wasnt fooled by my own wishful thinking.
