The BMW N53 (naturally aspired) and N54 (turbocharged) engines were among the first BMW engines to come with variable valve timing on the intake and exhaust camshafts. The N53 and N54 straight-six have unfairly earned a bad reputation for reliability with technicians due to timing chain and variable valve timing problems. The reputation comes from owners not keeping up with oil changes and it is difficult to check engine timing.
