Character

N43

"Direct injection 4-cyl. Injector failure, high-pressure fuel pump issues, lean-burn NOx sensor problems. Short production run. Avoid if possible — N46 or B48 are better choices."

M50

"Cast iron block legend. One of BMW's most reliable ever. M50TU added single VANOS. Strong internals handle 300k+ km. Cooling plastics only weakness."
