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.
