2015 BMW 528i N20 drivetrain malfunction and struggles to start after night
Hello, I'm struggling with a Drivetrain malfunction on my 2015 BMW 528i and error codes P0300 P0301 P0303 P0304.
In the morning, when the car starts after sitting overnight, it takes a while to start. Later it starts quickly, but in the mornings it sometimes takes about 3-4 seconds. Driving up to about 40 miles per hour everything works fine, but as soon as I get on the highway and press the accelerator more, the check engine light comes on and a "drivetrain malfunction" problem appears. When this problem occurs, the car really shakes while driving. I switch to manual and it drives well from M1 to M5, but cannot switch to M6-M8 without the car shaking. Stopping and turning off the engine resolves the issue until the next time I press the accelerator on the freeway. I have changed the spark plugs, replaced the ignition coils, and replaced the valvetrain motor. It helped me with other problems, but it doesn't resolve that. I am now preparing to replace the fuel injectors, but I am not sure if that's really the problem. How do I determine if it's really due to the fuel injectors? Is that right that this car only fits OE 13648625397 = BOSCH 0261500260 = BOSCH OLD = 62838. Doesn't interchangeable with 13647639994, 0261500172 or 13647597870? Because some places like oembimmerparts dot com shows that 13648625397 = 13647639994. Thanks for help. |

Just wanted to chime in, I had a drivetrain malfunction when I got on the highway and stepped on the gas. It turned out to be the vaccum pump. After that I could step on the gas in sport and redline and no malfunction.
