Disadvantages of the M276 DE30 engine

  • The most problematic place of this power unit is the timing chain tensioners.
  • If you miss their failure, you will have to change the timing kit with phase regulators.
  • Also on these engines, impulse disks on camshafts are often displaced.
  • Direct injection injectors are sensitive to the quality of the fuel consumed.
  • A couple of cases of scuffing due to catalyst crumbs have been described on specialized forums.
