I live in Beaverton, and found at least one station with ethanol free 92 octane gas at Dave's Palisades in West Linn (503-636-7935, 1680 Southshore Blvd). If that isn't convenient for you, check here.

So after replacing the Idle Control Valve AND keeping my car for almost 1 month, I had hoped the problem had been resolved. After my much anticipated fill-up today, I had the same erratic idle issue occur once again.
I drove the car home from the gas station and I was just sitting in my driveway watching the car in idle, and it randomly starting struggling and turned off. This happened two more times while in my driveway, each time happening about 2 minutes after start up. The car struggles idles at 500 rpm, then randomly spikes to 1k then to 250 a couple times then shuts off, it doesn't kick a code or anything. One thing I did notice was that immediately after the car shuts off it makes a double click noise. Anyone have any clues? I have this recorded as well, I might post it up here. I am beyond frustrated at this point, I would love to just let off some steam at my dealership. When I picked up the car I told them it may not fix the problem and that it may be fuel pump related. They said that they did not recognize some hosing/wiring inside my car which may be the cause of the issue, complete COP OUT in my opinion. My car had a IPE Valvtronic exhaust on it from the previous owner I had taken off before I purchased it, so I am guessing it's just the leftover module/wiring, which in no way would be causing this issue. I am at a loss for what I should do currently, any advice would be much appreciated. I figured I am going to finish this tank of gas and take the car to the dealership, and take a foreman with me and then go fill-up my next tank, to hopefully reproduce the issue in front of them, instead of showing them countless videos. Idle-stalling THREE times within the span of 1 hour is definitely not normal. Should I reach out to BMW of NA about this matter? |

^You should reach out to BMW NA if your dealership is unable to help you fix it.
I just dropped my car at the dealership, they said they will be opening a PUMA case. In the meantime they will be looking at the fuel system, purge valve, make sure everything there is suppose to be running perfect. I showed them gpitts's work sheets to give them an idea since they don't know what to look for. One thing in common, we all have no fault codes according to my foreman.

I've had my car back for over a week now (that's two fill-ups for me) and I've had no issues. Best of luck to you! These cars are a lot of fun to drive, but they're complex machines and occasionally get sick like we do.

Funny. I updated to 240E after I posted in this thread and I haven't had a single idle stumble. Nary a one.

When I first took my car in, the dealer could not find any issues and updated my firmware. I then experienced the same issue twice afterwards, and they ultimately resolved the issue. But the fact that they updated your firmware to a new revision, and they updated my firmware to a new revision in an attempt to address my issue makes me a little suspicious that there is an known idle / ignition related issue floating around out there that this firmware addresses...

I also had a contributing factor to my pre-update problems. I think the stall I experienced was due to an coilpack getting ready to fail (which it did 2 weeks later). Between having that replaced and the 240E update, this issue is resolved (for me). |

Like gpitts, I am already on 240E so that is not the issue for me either. Will take the print outs to my dealer as they may provide some insight for the service dept.
gpitts, any chance you can send me the PDF files? Thanks in advance! Ken

Just curious, how many of you here have aftermarket ECU? I have the Dinan ECU flash and my dealer wants to go back to stock since they could not find any fault code. I doubt they can find fault code even on the stock ECU.
Anybody have any idea whether the ECU can make a difference to diagnosis? I also have a Akrapovic Delete-R as well.

gpitts, will do!
As for the aftermarket, ECU, nothing here. My car is stock.

never happened during the 2 years that I had the car in NYC (93 octane). now happens intermittently in LA - bad batches of 91 octane seem to be the culprit.
of course, I could be wrong. Just my informal observation. Note: new plugs / 240E did not fix the issue. also, seems more likely to occur if I fill all the way.

I to thought it was bad gas. My car is 3 1/2 years old, didn't start until around 6 months ago. Unlike I did not move and have been patronizing the same Shell station for years, which carries 93 octane so octane is not the issue. I've tried various different Shell and Chevron stations an it happens no matter where I fill up so my less than scientific deduction is that gas is not the issue.
I am already on 240 and had the plugs replaced at 28.5k, car now at 35.5k...

My car is out of warranty too, I am putting the car back to stock exhaust + stock ECU before my dealer will agree to work on it. I hope they will see fault codes when I'm back to stock or else it will be for naught.

Ugh, that's unfortunate! The (non-VANOS related) components that were last replaced were the fuel pump repair kit (16-11-2-283-497) and the fuel tank breather (13-90-7-838-281). The other parts they replaced didn't seem to matter, as the next fill-up or two I'd experience the idle issue again. I can't say that this will address the issue with your car, but our symptoms do seem to be the same. I can only share my experience and hope that it helps you and others having this same issue.
