What Causes BMW Drivetrain Malfunction and Vehicle Shaking?
1 Answers
BMW drivetrain malfunction and vehicle shaking are typically caused by unbalanced deformation of the drive shaft, a condition more commonly found in vehicles that have experienced undercarriage collisions. When experiencing drivetrain malfunction and shaking in a BMW, it is unsafe to continue driving. Under safe conditions, immediately pull over and request roadside assistance to prevent further damage to the transmission. Main causes of drivetrain malfunction: Drivetrain malfunctions are generally attributed to failures in components such as the clutch, transmission, universal joint assembly, final drive, differential, and axle shafts. However, in reality, aside from these component failures being classified as drivetrain malfunctions, many unrelated issues can also trigger a "drivetrain malfunction" warning. These may include fuel pump failure, injector issues, solenoid valve problems, sensor malfunctions, or even damage to a single screw. Other potential causes of drivetrain malfunction: The engine control unit (ECU) may fail to respond or the program may not run properly; fuel pump or fuel pump sensor failure; injector damage; ignition coil failure; spark plug damage or carbon buildup; turbocharger wastegate failure (which may not necessarily be due to wastegate damage but could be caused by clogged internal filters); incorrect vacuum tube connection on the turbo wastegate; burned-out relay in the right-side fuse box of the trunk; VANOS solenoid valve failure; loose or damaged camshaft position sensor screws.
