There is no bulletin that I am aware of. However, I do know that BMW opened a PUMA case with my car. As far as I know, I was the first person in North America to experience the electric cooling fan-induced "limp" mode. I anticipate that there will be a bulletin on the issue in the future.

In the picture, I am flooring it. Pulled into my work parking lot and heard the fan blowing loudly. Same ole same ole.

Those are exactly the same symptoms I encountered on multiple occasions.

Here is a recap of the repairs performed on my soon to be departed F30 M-Sport 335i:

- Electric Cooling Fan Replaced (Twice)

- Water Pump Replaced (Once)

- Relay Replaced (Once)

- DME Replaced (Once)

- Rear Brake Pads Replaced (Twice)

- Rear Brakes Replaced (Once)

- Driver's Side Door Handle Replaced Due to Faulty Comfort Access (Once)

- Driver's Side Taillight Replaced (Once)

Problems that will not be repaired because I am getting a new car:

- Rust on Seat Frames

- Inability to Sync Phone Book/Contacts List (iPhone 4)

I'm bringing in the car tomorrow for damage they did remediating the rusty seat pans. The second time limp mode they did nothing but note it, "check" the car and release it to me. Should I mention the DME to the SA or wait until it does a limp again?

[TheObviousChild]

I emailed my SA so they have it on record. I'm guessing that since 335 M-Sport drivers are a small subset of all F30 drivers and the people experiencing this are an even smaller subset of that, that we will not get any official resolution in the form of a tech bulletin and, short of rebuilding our cars, we will be stuck with this for a while.

As I have mentioned, just convincing my dealership that the ASS could be coded to Last User Mode was a bit of a challenge and I didn't really get traction until I pointed out the specific tech bulletin for them to reference.

Those who ask why you would not want to have a turbo engine in the m3, well this is the answer. Nothing worse than on the track or on a road having fun, on a hot day and limp mode. I drive the piss out of my m3 in 100 degrees and simply runs like a champ.

I am going to hate babying the next m3 to not go into limp. Definetly having second thoughts on going bmw turbo. I was giving them the benefit of the doubt to fix this issue in the F series cars but right out of the gates here we go

Let's not forget that BMW is consistently rated as being average or below average in any and all reliability surveys so this shouldn't come as a surprise to anyone. Also, everyone should be well aware that BMW does conducting field testing on their cars before they're offically sold to the public but then they rely on the public/consumers to "complete the field testing." BMW figures this is the only way to get "real" data so the first couple of year purchases are the testers. BMW is one brand that you want to stay away from in the early model release. Wait until at least the refresh but the second to last or last year of that generation is the best and safest model year to buy.

Good luck to all of the testers and yes, it does sound like the fan issue or whatever they're saying it is the new hpfp issue. It bwm like 4 years before they figured out the hpfp issue. Let's hope this "fan" issue gets resolved a lot sooner.

Well, I just picked my car up at the dealership last night with 12 miles on it and today with 82 miles I experienced this issue. Glad to see Long Beach BMW is at least familiar with the issue so I have someone to go to there. Who did you talk to about the issue dark trigger?

[inChargeOfIT]

You will likely find that your dealership and BMWNA will (eventually) work with you to make things right.

My first F30 had some electronic steering issues and a gas pressure sensor that failed multiple times... I never made much traction working with the service manager and/or the sales guy, but after almost a dozen loaner cars within the first 2 months of ownership, I started demanding that the dealership's GM get involved, and I also demanded that a representative from BMWNA be involved as well. After a few meetings and a half dozen hate mails, things started rolling.

In the end (I cannot go into details) I walked out a very happy owner.

I went through a very similar issue with my Porsche, and my best friend spent more time in various A3 loaners than he did in his S4 for the first few months he had the car, so this is not that uncommon.. especially with new models.

But, you HAVE to insist that you are not happy with the car, you do not trust the car, the car has already lost resale value because of the repairs that have been done, and make sure you want to know about BMWNA's buy back program for lemons (and use the word lemon

They do not want cars returned as lemons (they cannot resale them), if they take your car back and get it fixed, they can CPO it.

Anyway, they might make you a nice offer on a different vehicle of your choosing, possibly with: loyalty discounts and cash incentives from the dealership, cash from BMW towards your next BMW, the dealership selling the car at ("no profit next sale") i.e., their cost... you will find that you can walk away with a nice smile on your face if you are patient and persistent.

Squeaky wheel gets the grease!

[Rustyboy155]

Yea, except my car is the only stick shift on the west coast currently and I don't really feel like waiting 2 months for a new car after waiting 2 months for this one and picking it up 2 days ago. I already got the car at invoice because of a screw up on the dealers part so this would be a disaster if I has to order a new car and all that.

[Sapper1]

I am new to BMW, but seems that they experience the same issues with new models as most other manufactures, Cadillac with the CTS, Chevy with the corvette and Camaro. Someone earlier mention you have to "Demand" and use the word "Lemon", I think this is more common in todays world, with pretty much everything. Thanks for the information though, I hope I dont experience a lot of the issues I have read about here; however if I do I feel comfortable due to the information learned here.

There are some bad scenarios I have been thinking about where this kind of behavior could be really bad. I hope they come out with something to address this to a conclusion. The only reason im still trying to hang in there with this car is because there is not much at all to replace it with that would be comparable at the same price point IMO

So far the new software flash has been good. My oil temperature has been in the "normal" operating range. If it goes into limp mode one more time I am going to Lemon Law it though.

Can you find out if there is a tech bulletin associated with the software flash you are getting? If this is in fact the fix, it will make it worlds easier for the rest of us to get it addressed armed with the official bulletin number.

Has anyone with a post 11/12 build had this issue?

[bthuss]

so thank god i didnt get my M performance pack installed last week, becuase i just had the dreaded dead turbo loss of power. surging and then no power. basically in any mode. loud fan running noise when i finally limped home.

its nice that BMW charged me for my M perf kit and then jacked that up too and "lost" the code sheet.

under 1400 miles on this car. i might be getting my money back for that seeing as how i cant trust this thing with the stock tune.

PIA.

oh an my car was built in february of 2013....

[xiljustin]

First limp mode @ 1200k they stated the car was in transport mode, and they corrected it. Everything's been fine until today 3200k car went into limp again. I'm taking it in for a second time.

Mind you, they just replaced all 4 rotors and pads due to the unbearable squealing.They glazed them after my first visit. Brakes are still squeaking....

Oh, and the AC hose is being replaced because its causing a vibration on the dash.

Oh, and upon pick up during my last visit, they scuffed my newly powder coated rims.

Ive made 5 trips to the deanship within 2 months of purchase. Not fun.

I have 4k on the clock and the squealing went away on its own. So maybe you should wait another 1500 miles or so.

[bthuss]

ok, i took my car in and deliberately did not mention this thread or forum to see what/if they could determine on their own. sure enough i get the call that they had to order the auxilary fan unit and overnight it in for replacement. there were codes thrown all over when the service dept hooked it up.

[xiljustin]

Did the engine light go off?

oddly enough....no

there was no sign of anything abnormal on the dash at all.

Same here, however, after that one initial limp mode, I have yet to experience it again.

[Jeff_in_Oviedo]

I just experienced something similar this morning. I was driving in sport mode, manually shifting my automatic. I had it around 2k rpms, and applied about 50% throttle, but the car accelerated as if I was at maybe 10% throttle...no power. Its not like there was turbo lag...there was just no power. It was literally as if the ecu was capping the actual throttle to 10%, regardless of physical throttle input. I switched it to comfort and full-auto, and it was fine. I don't know if the electric fan was doing anything abnormal, as I was doing around 50mph and windnoise was high.

[bthuss]

my car was fine (after i shut it off once i got home) for the next 2 days of driving. I took it in anyhow and they immediately found codes all over the place and overnighted in a new Aux. cooling fan. Again, i made no mention of what i thought it might be or this thread/forum so it looks like the dealers may actually know about the issue fairly well.

Aux cooling fan didn't help me. Limp mode month after. Software flash is holding so far.
