Four problems related to check engine light on have been reported for the 2009 BMW 335. The most recently reported issues are listed below.
I buy my 2009 BMW 335i with 39,700 miles, full BMW service was done the same day, my next service was at 49,000 miles however at around 48,000 miles. When driving to work on the highway going 50mph I had to move over to the passing lane and when I attempted to accelerate about at 65mph the car started to shake very bad and the engine light came on and I loss power had to slow down to 20-25mph could have cause an accident as I was in the faster lane and car slow down rapidly!! thank god I was able to move all the way over to the slower lane with little issue. After I pulled over I turned the car off and open the hood as my oil temp was just about at 250*, under hood temps was hot but not anything crazy, everything looks good so I started the car and it idle like normal and the engine light was now gone, I close the hood and was able to drive the car like normal, so I took the car to the local BMW dealer in my work area and they told me the issue I am having is cause by the hpfp high pressure fuel pump, so they reply it and everything seems normal for another 2,000 miles then I had the same issue again! this time I was heading home and it happened when I was trying to accelerate with moving traffic omg that was bad all most cause a major accident with all the cars, trucks behind me had to slow down rapidly . . Was going 30mph and tried to speed up to 60 . . At around 45mph car lost power and was shaking worst than the first time this happened, engine light came on, again thank god I was able to pull over, I turn the car off and waited for 5-6min than turn it back on, this time the engine light remain on, my oil temp was around 190*, the car still idle and drive as normal even with the engine light on, took it to my local BMW dealer in my home area and they found this time is two bad injectors one at cylinder 1 and the other at cylinder 5 . Cost of repair $1. 1k.
Vehicle oil temp was just under 250. Vehicle shakes when accelerating on the highway or on an incline. Engine light comes on and you can feel the vehicle misfiring in the gas peddle. Vehicle continues to shake in park. Dealer advised to turn the vehicle off and let it sit for 30 min before driving again. Seems to be a temporary fix until the engine temp increases to just under 250 or driving on a incline on the hwy. Previously had no issues with this vehicle until dealer replaced a hfp (recall notice) during an oil change. This will be the third complaint about this issue since 11/23/11 that the dealer has not been able to fix. Previously been told injectors were malfunctioning due to programing and also bad gas. I have always used premium 91+ oct gas. Recently the dealer put in a fuel additive and advised me to use shell or chevron premium gas in the future. I drove out the fuel additive tank, no issues and refueled at shell using premium 91 power v. Forty five minutes later, my vehicle began to shake on the hwy once again and my check engine light came on. I was forced to suddenly slow down on the highway to a speed / gear where I wouldn't shake. Previous driving history in eu with no issues on the autobahn and the vehicle is a us spec. Once the vehicle was shipped to CA, I drove it to az (800 miles) with no issues and continued to drive the car until sept when I had my oil changed and my hfp replaced. My first long hwy drive since the oil change / hfp was replaced, we encountered this issue.
My BMW turned off on the highway. Engine light came on and car stopped.
Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6) I am the owner of a 2009 BMW 335i purchased August 2009. On April 6, 2010, I started the engine in the morning and was greeted with long cranks and the check engine light turned on with an error message of engine failure, reduced power. The car has been fine before this morning at 7,200 miles approx. I contacted the dealer and was told to bring it in. The car was still drivable. On the way to the dealership, the car stalled and completely lose power on the highway and on the inside street causing me to have to quickly put the gear in p and restart the car. I informed the dealer about the stall and engine failure but was met with no regards. The dealer informed me that it is a high performance fuel pump failure. Please investigate the issue as I do not want to be driving on the highway and have the engine completely stall and shut down again. [xxx].
