Four problems related to car stall have been reported for the 2008 BMW 335. The most recently reported issues are listed below.
The engine is idling very roughly at a full stop whether its a traffic light, or just stop and go traffic. The rpms will spike to 750-800 rpms and drop below 5-400 rpms randomly causing the entire car to shake violently, and stall at times. The incident seems common with my model car though online forums and friends that have the same car and the 328 with n54 engine. My main issue is that there is no malfunction code associated with it, and it happens randomly; sometimes when the car is cold, sometimes at running temp, sometime with ac on, sometimes with ac off. There doesn't seem to be a specific variable causing the issue, but it is a major issue non the less, therefor BMW dealership can't seem to figure out a fix for my problem and continuously turn me away even though I have extended bumper to bumper warranty. This issue has become a safety concern of mine and I dont want it to get worse and causing an sudden loss of power or an accident. Ive noticed that there was a recall for 2007-2011 3-series for loss of electrical power/stalling, but I'm not sure if its the same circumstance for my car or different.
Tl- the contact owns a 2008 BMW 335xi. The contact stated that while driving approximately 35 mph, the vehicle began to hesitate and stalled. The vehicle was towed to the dealer for diagnostic testing. The technician stated that the fuel injectors and spark plugs would have to be replaced. The vehicle was repaired. The approximate failure mileage was 76,400. Kmj.
After starting my BMW it occasionally will run fine for between several hundred feet and three quarters of a mile and then briefly stall. This has happened while on the highway. It seem to happen after it has been parked for a short period of time (anywhere from a few minutes to a little over an hour). One time I had to coast off the road and re-start the car. The other two times the car has briefly stalled (all the dash lights come on as if it has been shut off with the key on), the car slowed down and then the motor caught again and began running normally. My car has been into the dealer several times. The last time they replaced the #4 spark plug and this seems to have fixed another problem I had with the car running with low power for a few moments, however it has not cured the stalling issue. I am reporting this because I think that it could be very dangerous if someone were passing a car or in heavy highway traffic when this happened. I am hoping that the dealer will eventually be able to fix my problem. I have approximately 44,000 miles on my car so I have about 8,000 miles left in warranty.
We were driving on the florida turnpike for ~100 miles and then exited. At the first red light the car stalled and refused to run normally. It sputtered and stalled repeatedly. We were fortunate that a dealer was within 1 mile and was able to effect repair. The problem was failure of a pressure pump which we were told is a known problem with car. BMW has not despite the frequency of this problem put out a safety recall. This is a very unsafe problem. Had the pump failed a few minutes earlier we would have stalled on the FL. Turnpike while traveling 70 miles per hour. The government should require BMW recall all vehicles with this pump. Our car had only 4400 miles on it at time of failure and was in fro servicing 3 weeks prior. There is no excuse for this condition. When we contacted the dealer on the phone who repaired our vehicle he diagnosed the problem on the phone. Obviously this is a well known to BMW and frequent problem.
