BMW N20 / N26 Family

All Engines

Problems

  • Carbon deposits
  • High pressure fuel pump (HPFP) – symptoms often include the car taking a long time to start – has been addressed on later engines
  • Some engines suffer from stretched timing chains; there was a TSB in 2012 to replace the oil seal on the chain tensioner and BMW redesigned the timing chain in 2015. Some cars, but not all, had recalls issued for MY12-14.
