Eight problems related to fuel injector have been reported for the 2007 BMW 335. The most recently reported issues are listed below.
I have owned this 2007 335i for 2 1/2 years. I am a 59 year old female that drives very conservatively. In the 2 1/2 years that I have owned this vehicle, the fuel pump has been replaced twice. Four months ago the injectors had to be replaced and this past Friday the electronic water pump and electronic thermostat had to be replaced. Not typical of any BMW I have owned in the past 12-15 years. I contacted our local BMW dealership and they knew of no problems with this particular model. I contacted BMW today regarding this model and they took the information for review which to me means file 13. BMW knows there is a problem with the water pumps and the thermostats on this particular model and they choose to do nothing about it. They also know there is a problem with the injectors and they choose to do nothing. I was told that the NHTSA makes the determination on all recalls not the individual car makers.
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 contact owns a 2007 BMW 335i. While driving approximately 65 mph and accelerating the contact felt a vibration in the front end of the vehicle. The failure occurred intermittently. The contact stated that there was a voluntary recall for the high pressure fuel pump and a software update. The vehicle was taken into the dealer for the recall repairs and to diagnose the failure of the vibration. The technicians stated that the low pressure fuel pump and spark plugs needed to be replaced. The repairs were not made by the dealer. The vehicle was taken to an independent mechanic where a low pressure fuel pump and spark plugs were replaced. After the repairs were made the contact continued to experience the failure. The vehicle was taken to the dealer where the technician stated that the fuel injector needed to be replaced. The vehicle was not repaired. The contact stated that she had an after market warranty and they would have the vehicle inspected by one of their inspectors. The approximate failure mileage was 70,000.

Problem with lost engine power in my 2007 model BMW 335i convertible car five times in 2009. One instance involved a fuel line separation on an expressway outside chicago. Each time the vehicle was taken back to BMW dealership for service. Fuel injectors were replaced. Pollution control devices were replaced. But problem was not corrected. Finally, the high pressure fuel injection pump was replaced and the warranty on it was extended to 100,000 miles. The problem appeared to be resolved.

Purchased a BMW 335i coupe from BMW of manhattan and it has broken down half a dozen times and spent over 30 consecutive days at the service dept. When it broke down the first time due to faulty fuel pump that I was told is on back order then broke down few more times due to similar problems including recently car dying on me due to fuel injector malfunction. 23k miles on the car.
BMW 335i had a fuel injector problem and within 2 weeks I have a microfilter problem. In 3 weeks, my car has been in the shop twice.
