No random stalls today for me though. Its purely hypothesis, but does it seem to happen more when the climate is warmer/more humid for you guys as well? Yesterday, I experienced probably about 3 stalls on my commute home (high humidity, ~80F). Today temps dropped to around low 60F, no stalls or engine shuddering for that matter.

Never had a tune in my car and I'm experiencing this problem at random times. It seems when it got warmer it started to happen. We have been in ~85 weather for past 5 days in Chicago. Fk maybe it's because of some magnetic shit from the sun...... haha .....fk .... i don't know.

The problem with BMW is they've taught us, this is a good car, one that you love. So stalling randomly is just something you have to expect from a car this good. All I can say is stalling is NOT normal!

I'm not sure it's the same thing. I have a 328 with Automatic (2007) and it would randomly do the same thing. I took it into BMW for a broken window switch and asked them to look into it. I was not very hopeful as it was intermittent and the advisor agreed with me that it would be hard to find but he said he would try.

To my surprise they found the problem. I don't have the paperwork handy, but it seems there is a sensor under the valve head cover that was acting up. It was causing the engine to stall out when coming to stops or slowing down before turning from one street onto another. By playing with the sensor they were actually able to recreate the situation. The fix was to replace that sensor (sorry I can't remember what it was called, only that it was under the valve head cover)

Like I said, it might not be the same thing, but it can't hurt to ask to have the sensor checked.

This is the situation that ive had it happen to me in.
Im coming to a stoplight and im coasting on third gear. Im like 7/8th of the way to a full stop and right before i come to a stop and i push the clutch in, baM, stall.. It didnt even sound like stall. Its more like the engine died quietly... This is becuase as you coast, since there is no fuel being supplied to the engine to this point pushing the clutch in is like making the car gasp for gas, the rpms drop too low before the fuel supply is able to start burning again...

Edit: this hasnt happened to me in a long time though, ive had this happen to me like 3 or 4 times in the lifetime of my car

No way does coasting in gear have anything to do with this

I have a 6MT too, and always have driven a manual so coasting in gear is the norm for me.

I have "coasted in gear" down NUMBEROUS hills and rds in my area with ZERO problems. And some of these hills are literally a mile... downhill for a mile with NO brakes is awesome - another reason why I love a MT.

also, not sure what year it was started, but ALL manual cars while IN GEAR and NOT on the gas, does not use gas.

Something similar happened to my 08 335xi e90(auto) back in november. The car had about 70k miles on it at the time and been through 2-3 hpfp replacements. here are my symptoms.
The car starts up fine in the morning with normal idle but after driving it to my destination it would have the rough idle then completely shut off. I tried to give it some gas to keep it from stalling but the CEL came on with limp mode. I disconnected the battery and let it sit for about 20-30 minutes and it was fine. drive off and when i turn the car off and try to start again same thing would happen. Anyways this happened for about a week and a half and thing went away by itself. I thought it was the HPFP but dealer couldn't check if the CEL wasn't on. So I just came to my own conclusion that it was bad gas. I don't go to that gas station and have no problems since(crossing fingers)

I wonder if your car was plagued by a bad vanos intake solenoid like 335i's are. If I"m not mistaken we both have vanos but N54 335's don't have valvetronic.

As have i. I ALWAYS Coast when coming to a stop.

What i was explaining is how I experienced the random stalling. the ones i ever experienced happened as SOON as i came to a compete stop and my post was me explaining the cause

Edit: but also yeah. i was making the point that my car DOES NOT use gas when coasting because a couple of years ago there was a post that was heatedly debating whether or not the car did in fact use gas when coasting.

Gotcha.

... I think if you would serach for that... you may be surprised at who started that thread - ME haha, but i didn't start it as a "using gas while coasting" thread, but it quickly morphed into that. I remember my starting arguement was something about coasting in N or in gear and how while coasting in N in fact DOES USE GAS, while coasting in gear DOES NOT USE GAS.

2012 335 e92 6mt with aprx 4600 miles. Every account on this thread hits home. I am glad i am not going crazy. I took it in to my local dealer and they said they increased the idle. on my way home it stalled ...

[AliciaDino]

Hi, this post is kind of old and i don't know if anyone is still viewing it or not. But, I have the same issue with my 2011. It started when i had all but 1,525 miles on it.

Outcome of it all, BMW NA offered a buyback within 1 week of me contacting them. They were citing that they'll have a "fix" in August 2012 (if i wanted to stick with it and wait for a fix). But even then that's not guaranteed.

I finally got them to offer me a replacement (with a 2013).

I don't know which option i'll choose yet, but this "problem" is an apparent one with BMW NA, but they've been really quiet about the subject or anything related to it. So to whoever is still reading (if any) i suggest you make them take it back.

[mashimarho]

Mine did it a while back during idle in the garage. Just like the video above. Rpm goes up n down... Then. Boom. Stall.

[Sam335ix]

My idle at times goes up and down constantly and it levels out. I had an issue with my high pressure fuel sensor not reading the correct PSI in the sensor. We unplugged it and plugged it back in and it runs fine. I suggest if you have the same problem, unplug your high pressure fuel sensor and reconnect it. It might help.

[Badboy8813]

this might be your low pressure fuel pump sensor going out

[MotorenWerkeN52]

I had that exact same issue today for the first time. I was coming to a stop at a red light, as I pushed in the clutch and press the brake the car stalled. The first few times the rpm fell low but came back up. I wonder if it has something to do with the heat and humidity.

[scrappyz323]

I have an 07 328i 6mt and I have owned the car for about two months, this has happened to me about four times and everytime it was when I was downshifting into third gear. It is always third gear. I don't remember what happened the first two times but the last two I went from 6th to 5th to 3rd when coming up to a stop light. The engine stalling is so quiet that I don't even notice it. I just realize it when I lose power steering. Should I take it in to get it checked at the dealer or will that do me no good?

[AliciaDino]

You guys are obviously not reading, BMW NA has acknowledge the defect. They are taking my 2011 car back and replacing with a 2013. I'm suggesting everyone with the issue to fight for them to fix it or replace it. No one should spend upwards of $50k for scrap metal.

[carl_d]

I have the stalling problem on my Nov 2010 6SP N55 E90. Only seems to happen when engine is part warm but cannot repeat it consistently. I drive to junction and press clutch down and "bang" engine stops as if someone hits the stop button. Seems to be a software issue? Only had problem after a software load on car.

Interesting... I just took my car to the dealer a week before this started to happen. I wonder if they did a software update that could be causing this.

I could do that but I really don't want the F30... I am hoping they can find a fix for this soon. You said they are going to have a fix in August?

It hasn't really been an issue for me. The car only stalled once and that was over a week ago. However, I have noticed that now the RPM goes down low and bounces back to idle unlike before. Before when I pushed the clutch in, it would just come down and stop at idle.

The 2013 drives like &*(^^*(^&(. They should replace your 2011 with a 2007-08, that would be moving in the right direction.

Worst case, my car has stalled over 6 times over 30 mins at 6 different junctions! There are no warning lights and no other engine issues. This is a major safety issue and seems to occur randomly.

I have other issues which also seem to be software related: wipers do not understand the car's speed; Auto Air Cond often makes cabin calmly/stuffy and only cools top of cabin; error message after inserting key says "key not inserted" but the car starts! All these appeared after a software load.

Car is off tomorrow to dealer so lets hope they find a fix.
