I got a call and was told that BMW instructed them to replace the oil filter and return the car back to me. They didn't even drain and replace the oil in the engine. The whole thing makes no sense to me BMW will have you replace bolts, nuts and washers when performing repairs.

I drove the car again and when my speed goes up the engine keeps the noise but I can't feel the shake. The noise is best described as a stutter. I haven't noticed any performance issues. Hi and thank you for contacting YourMechanic. What seems to have happened is that the oil level was too low causing the engine bearings to have less clearance on them, making the rods bounce around. This is the stutter feeling that is occurring from the engine. I recommend topping off the oil and running the engine to listen for any more stuttering noises.

If the noise goes away, then the engine was just too low on oil. If the noise continues, then there may have been engine damage due to running at highway speeds with low oil. If you need further assistance in troubleshooting your engine vibration, then seek out a professional, such as one from YourMechanic, to help you determine why your car is making this noise and how to repair it.
