  • Most often, Opel owners on the forums complain about failures in the ignition system;
  • In second place in popularity here is the failure of one or another sensor;
  • From low-quality oil at high mileage, hydraulic lifters can knock;
  • The timing belt serves approximately 50 – 60 thousand km, however, when it breaks, the valves do not bend.
