Engine codes of this version: N57D30O0, N57D30O1, N57D30OL.

Faults of the N57D30O0 engine

The documented engine faults that affect this version and its years, from most to least important.

  1. 1Critical severityFrequency: Very frequentEmissions controlEGR cooler leaks with risk of engine fireYes: like the N47 and B47, the N57 is covered by BMW's service campaign for EGR cooler leaks, which can mix coolant with soot and oil to combustion temperatures. BMW checks free of charge the 6-cylinder engines built between July 2012 and June 2015 because of the fire risk.
  2. 2Critical severityFrequency: CommonTimingRear timing chain wearThe N57 inherits from the N47 the timing chain at the rear of the block, next to the gearbox, which complicates any repair. Unlike the N47, there is no documented campaign or wave of mass claims, and cases of serious wear appear mainly above 200,000 km.
  3. 3Medium severityFrequency: CommonOtherCrankshaft pulley vibration damper wearThe N57's crankshaft vibration damper (pulley) wears with use and, according to a technical guide to the engine, usually needs replacing between 80,000 and 120,000 km, giving warning with abnormal noises before failing completely.Appears at around 80,000 km
