2007 BMW 335I: misfire or rough idle

Filed Jun 26, 2020 · Fuel system · 87,354 miles · FL

There is already a recall for the fuel injectors in vehicles like mine but my VIN number is not apart of the recall. I am having the same issues stated in the recall. Recall sib 13 01 20 which is for vehicles like mine manufactured between 04/07 and 11/08. My vehicle was manufactured in 07/07 but somehow it was not included. I have been troubleshooting an issue with the vehicle hesitating and misfiring and it is due to the fuel injectors leaking into the cylinder. I have replaced all spark plugs and ignition coils and there is evidence that the spark plugs have fuel on them due to the leaking fuel injector. When I start the vehicle it starts normally but after idling for 5 minutes it begins to misfire with white plumes of smoke exiting the exhaust. The vehicle was not driven before or warmed up before this happened. I have also had this exact same issue happen to me as I am sitting at a red light the vehicle will hesitate, misfire and a white plume of smoke comes out of the exhaust. This hesitation and misfire has also happened to me while driving in the city in motion at about 40-50mph. The car misfires/hesitates and regains power immediately. Upon inspection of the spark plugs, cylinder 3 was saturated in fuel.

Car started to rattle especially upon pressing gas pedal while running at around 50mph in a freeway. Significant reduced power was noticed. Soon "service engine soon" lit on the tachometer. When stopped a raw gas to rotten egg smell was around the car. By turning on/off ignition several times, it stopped rattling and regained full power. Same issue happened again on a local road at around 50mph about a month later. Power regain was achieved through same way. "service engine soon" light went off 24hrs later. Brought the car in to a local bmw center. Upon diagnosis, cylinder #2 misfire and both pre-cat or post-cat oxygen sensor low response. A service agent decided not to do anything at the moment because he couldn't replicate the issue I described although he did find the malfunction codes. He instead told me to bring the car when the same symptom occurs. He also said that the technician who looked at the car believed that a faulty fuel injector might have caused the misfire and both oxygen sensors malfunction consequently.

The car stalled and lost power on highway. Engine light came on . Rough idling. First incident occurred september 2011. The second incident happened oct 26, 2011. Both times the car stalled and lost power on the highway. I believe that this created a very dangerous and life threatening situation for me and others on the highway.

Long cranks to start up engine and misfires upon cold start up almost every day. Often gets cel but dealer denies warranty/recall work on high pressure fuel pump (hpfp hereon) because I didn't have exact code they are seeking for. They confirmed the symptom but "unless car breaks down on the road or get the exact code, they will not replace failed part". Basically saying they will not voluntarily resolve problem unless they are forced to. Hpfp failure on bmw n54 engine platform is already well known fact hence bmw put extended warranty on hpfp. But it's not a recall and many times dealer denies to replace although they confirm the symptom and possible danger associated with the failed parts on vehicles. All they did was updating the dme program that supposedly fix the problem but long crank still happens everyday.

Owner of a 2007 bmw 335i coupe. Noticed a problem with rough idles and long cranks at start-up. As time went by, the long cranks and rough idles became more frequent. While driving onto the freeway via freeway on ramp, fuel pump failed while I was merging and engine was cut to half power "limp-mode." car had significant loss of power and I was almost rear-ended by a semi that was driving in the slow lane.

Constant failure in my 2007 bmw 335i sedan. Random loss of power when driving on the road. Lights do not light up the path of driving very well. I have taken my vehicle in at least 6-7 times for these issues and it has not been fixed. This is a known issue with this model. I do not know what else to do. I would hope bmw would recall such a defect. Per bmw recommendation I had the engine decarbonized as they said this would make the vehicle run to spec. The fuel pump was recently replaced as it was faulty and a new spark plug put in place. The car now runs rough and the engine is loud. Everytime I take it to bmw they say its running fine. I will bring my vehicle in once again tomorrow to have them take a look at it.

My previous car was a 2007 bmw 335i coupe. After a couple of months of owning the car, the car was diagnosed with a faulty fuel pump. Subsequently, I purchased a 2008 335i convertible. After driving the car for a couple of thousand miles, the car started showing signs of a faulty fuel pump (long crank times). Yesterday, the engine malfunction light came on and the issue was determined to be that of the faulty fuel pump. At this point, the car went into limp mode with reduced power. Additionally, there was shaking and the car was misfiring and running very rough. This is clearly a huge defect with the 335i engines. It is a safety hazard should the fuel pump break while the car is on a highway, or in a deserted location with no access to a repair shop. I would appreciate if this issue is given the seriousness that it deserves.

Rough idle with fluctuating RPM, long crank before engine turns over on ignition. At first it was once a month occurrence, soon it turned into once a week and became almost a sure-thing. Took it to a bmw deal who replaced a fuel pump. Now long crank and fluctuating RPM at idle is mostly gone but rarely happens again. Also, sidewall of front passenger side run-flat tire (rft) has a bubble even though the tire hasn't experience any shock (from potholes, etc).

Experienced fuel pump failure on my 2007 bmw 335i and became a safety hazard to others driving behind me on my way to work. Started experiencing symptoms as recently as a month ago, such as long engine crank times, very rough idling upon startup, and occasional "limp mode" performance. In spite of all this, the dealership did not work on my car until I experienced a "service engine soon" (ses) warning light. The fuel pump progressively got worse where the engine would shudder when revving over 2000rpms, and the car perpetually remained in limp mode where it is not able to accelerate in a safe enough manner to drive on public roads and highways. I was finally able to bring my car in for warranty repair when the ses light came on at 7/25/07 on my 02/07 production vehicle. I was told that there is over a one month wait for a fuel pump replacement.

Bmw 335 coupe hpfp (high pressure fuel pump for direct injection) failed before 4,000 miles. No signs of failure, car started to run rough, went into "limp" mode, and then would not restart without dying again after a few moments. Car was towed to the dealer, and was diagnosed as fuel pump failure. I had to wait 7+ weeks with the car in service because the fuel pump was on international backorder with 400+ units on backorder! Pump was replaced after being in the shop for 7+ weeks, and car is running good again.
