BMW isn't in a rush to fix this problem as it probably doesn't bother too many customers. I'm sure the vast majority don't even know about the lag issue. |

OK that's nice...good infighting.

anyway, the lag has already been proven using the procede datalogging function.

On a related note, I did get my boost gauge in yesterday, so in the coming week, I'll hopefully be able to get some interesting "peak boost" numbers at various RPM. I can tell you RIGHT NOW that with the testing I did yesterday, the car was seeing a laughable 2-3 psi before 2000 rpm. Peak torque my ass. I'll get more concrete data soon though. |

WRT your boost gauge, is it any different right after you start the car? |

I was told it wasa function of the dyno resistance kicking in or a function of the dyno that created that dip. ?? In any case i will repost. It definitely showed strong torque from low RPM. I didn't think it needed my name etc, on it. |

Was sitting at a stop light today and at idle my car, for lack of a better explanation, started to idle a little rugged, I even noticed the tac bounce a little, although just for a second. After I took off I noticed my gas mileage and odometer and Ipod settings were all reset....not the permanent mileage but the trip meter was back to 0 and the gas milage ave was reset. Looks like Big Brother BMW was eavesdropping on me...anyway, my wife commented that the car sounded different and I noticed it too. It just seemed a little louder under WOT. Yes the lag is still there. I dunno, maybe the sun and the moon and the earth are alligned just right.

Wow, I missed a lot.
First, I would be happy to contribute to help others with dyno costs that will help the cause. I am a bit confused on the dyno that holds the RPM at a fixed level. Is this something done on MT and AT cars? If the RPM s are held then will the results help in comparison to the BMW dyno they advertise or will that make an apples and oranges thing out of it since the BMW chart is with throttle open?. Has anyone noticed a change in the performance when it is raining or very humid? This may sound odd but that is something I ran into with my car. When it would be raining out the car would hesitate and feel sand bagged more than usual. And for all the dealers and SA reading this, if you put that the car is performing normal or within spec, then comment that there will be a fix, or that they are working on it, you just busted yourself lying! Most things that are normal, operating as they should, within specs, (or any other colorful wordplay you use to describe it) do not need "a fix" or for them to be working on it.(unless it is BMW working on detuning what seemed like a very powerful engine). No other news as of now, but will check and let you know.

BMW has totally destroyed my enthusiasm for this car. I still like it, but not like before.
I have a few little issues, including likely early HPFP problems (i guess -- on a late Dec 07 build 08), still on pre 29.2 (I presume). I don't want to get little things fixed or get the service I've paid for, because some twit won't think twice about updating my software. Yes, I can say please don't -- but that still only cuts down the chance. The cost of this move to BMW is far greater than the savings in repaired parts. I've told at least 20 people who I've driven in my car that its my first and last BMW. I'm going back to Lexus or something else next time..... I hope a fix will come and these worries will dissipate, but in the meantime, I feel trapped with a pseudo-warranty. If a bulb goes out, a radio gets flakey, etc, all of the sudden the car is neutered. Aside from that, maybe due to HPFP early stages, the car seems uneven. Some days strong power, butt dyno like I expect, other days its like our minivan (which is quick for a minivan, but not a 335). For the same reasons, I don't dare take it in for service. It may be a flakey temperature sensor, but I don't want to chance NEVER having the power I expect. Thanks to everyone who has pursued information and fixes and keeping us up to date... I wish success to all of us |

Are you serious? Think what through? This is my first and last BMW also. Have you read anything on this topic? Your first sentence says it all by stating the car is "neutered." Maybe you are comfortable with purchasing a 50k car and having BMW change the characteristics and then continually lie to you that it is running the same as when you first bought it. Sorry to everyone else for going OT but I just can not stand idiotic posts like these.

RBBMW, to address your question about more "lag" or hesitation in the rain...well, not to be too obvious about this, but, it's probably just the tires slipping a bit and the car cutting power. My car does this in the rain all the time and MANY times the traction light does not blink. You really have to get a few revolutions of slip on a tire to light that light. Trust me that the system is braking and pulling power often in the rain, despite no light showing. On a related side note, now that I have my boost gauge, it's funny to see that if I do a stupid full throttle launch in the rain, and the traction control goes apeshit, my max boost is quite low. Just neat to see the car thinking and trying to manage the loss of traction. |

If I had to replace my 335 tomorrow I would still get another. I understand the angst, but I agree with BMWGSXR. There will be a fix for this. Moreover, as much as I love the N54 power, it is the handling that is what keeps me a BMW fan.
