  • The most serious problem is the cracking of the cylinder head after overheating;
  • It is necessary to monitor the condition of the timing belt, since its breakage is fatal for the motor;
  • On long runs, the engine often consumes oil, up to a liter per 1000 km;
  • Also, there are quite often leaks in the injection pump due to wear of its gaskets.
