Disadvantages of the VW ARG engine

  • This motor is quite reliable and often only worries about the timing chain tensioner;
  • Also, the intake manifold damper regulator periodically fails;
  • The reason for floating engine speeds is usually a dirty throttle or injectors;
  • The antifreeze temperature sensor and air flow meter have a low resource;
  • The crankcase ventilation is regularly clogged, which leads to thrust failures, etc.
