I would demand it ether be rectified or replaced, no questions. It is not normal and will absolutely affect the value of your car long term. Question is not whether or not they can fix it but how they will handle the situation.

Whether it affects your daily driving is beside the question. Something is not right. It's a matter of principal. Every manufacturer has any number of cars produced each year which will be defective. They should admit that much and act accordingly.

I totally agree, as does my service manager.

That was kind of my thought process getting into this whole mess, now that it's been to the dealership 4 times for unfixed CEL's, isn't this history available for a future purchaser?

Let me ask you this; Have you driven another car to see if the same thing happens? If you have and it didn't, then you have a better chance than if you have and it did. If the same thing happened in another car they can say its working as intended to keep emissions in check.

As far as future purchasers, dealerships are not supposed to give out the service history to anybody except the owner of the car. It says so right in the software and they have to agree to it to even get the history. My friend went through hell trying to get the service history of the X5M he bought.

My service manager claims that this issue is specific to manual transmission 335's with the MPPK. I had enough trouble finding a m/t 335 to test drive prior to ordering one, I doubt I'll just be able to find a m/t 335 with MPPK at a dealership to test this out on.

Good insight on the service history, I appreciate it.

[jon102034050]

Well, small update- Service manager claims that he spoke with BMW and a software fix is due in March for this issue.

In the meantime, he said we can replace the mppk airbox with the stock one and that this should fix the issue. Anybody buy this?

[Mike_L]

How can the airbox be the issue, when its basically stock with a hole cut in the front? If that was the case, everybody with aftermarket intakes and the MPPK would have the same problem. I don't buy it for one second.

Haha, exactly my thought.

Think about it this way, they're going to supposedly fix a software issue with hardware? Confusing.

[RoundelM3]

It takes all of 20 minutes to change out the lower airbox back to the stock one. Why not try that and see if it does fix the problem? That hole in the airbox allows slightly more air into the intake, supposedly to increase the intake sound, but it could have an effect on what the MAF sends to the ECU.

[jon102034050]

Totally agree, problem is that I don't have my stock airbox. My MPPK was port installed so I never got it. I'm waiting on a call back from the dealer, going to make them foot the bill on this one.

I still have mine (installed it myself, dealer installed the software). Where are you located? Mine is just taking up space on a shelf in my garage. Or, you could see if the dealer would locate one for you or maybe someone in your area has theirs. Last, and probably least desirable would be to plug that hole with duct tape or some other method.

MN. Thanks for the offer, I'm fairly confident that the dealership will have no issue acquiring and installing a new one.

Yeah, I'd think so too...I know mine would. One other thing...you're in a fairly cold climate area. I wonder if that might be a contributing factor?

Don't think so, we actually had a period of unseasonably warm weather here recently and whether it was warm or cold, same results. I've been able to reproduce it when it was 70+ degrees or 20 degrees.

I'll keep the thread updated as to what happens, thanks!

[RoundelM3]

Ok - we'll all be listening in. Meantime, maybe the duct tape thing would be worth trying, just to prove a point? Looking at the airbox in mine, there is a sensor in the upper half, but nothing on the bottom, so it's got to have something to do with airflow - unless that opening has some sort of "harmonic" effect, causing the sensor to send a fault signal.

Now I remember why I don't come around here any more. Thanks for the reminder. Please sell your BMW and buy something else. This is EASILY the most ridiculous "lemon" claim I've ever heard.

By the way, suddenly throwing a car that's been cruising at speed into neutral will thermally shock the cats, and potentially skew O2 readings on a motor as lean as these. It's generally not a good thing to do and there's zero reason to ever do it.

So you're saying this is expected? Maybe we should tell the last 5 car manufacturers I've owned cars with, huh?

No, with all due respect, I'm saying it's STUPID. Cars ain't what they used to be. The systems are optimized at levels that we've never seen before in an effort to maximize output and minimize fuel consumption and emissions. It's not a stretch to suggest that the complexity of the systems are approaching those of a fine Swiss movement.

What you're doing is suddenly and rapidly shocking the system which is irrational and definitely something that any engineer would ever anticipate during the development cycle.

I might give you the benefit of the doubt if you did't pull the lemon card. That's assinine. This in no way affects the operation, performance, or safety of the car. You're just being a Mr. Whiney Pants.

Sorry if you're offended. But you're abusing a system that was designed to protect consumers from legitimate defects and irresponsible manufacturers/dealers.

Again, please just sell your BMW and move on. Have a nice day.

I shift directly into neutral and cost down the off ramp for the last 22 years of driving.

It's absurd that a car would throw a cel for this. Car is bad, lemon it!

The reason I pulled the lemon card was to get my dealers a** in gear about finding a solution to this problem. I'm not necessarily going to claim it as a lemon. They hardly gave me the time of day until I presented them with the formal lemon law letter. A couple days later, I'd already gotten word back from BMW about a software fix due out on a specific date. Thanks for your input.

Thanks billiebob, I appreciate the input. I'll let you know how it comes out.

I just got this.
MPPK.
2012 build. So goofy....

The issue is pretty strange, I will admit this.

To give a update, my dealer pulled the MPPK airbox and put a new stock one in, and I haven't been able to reproduce it yet. As of now, we're still waiting on the software update thats supposedly due out soon. Once thats out, we'll update and replace the airbox w/ the MPPK one.

Seems janky as h*ll, but I guess thats the way the cookie crumbles.
