Disadvantages of the D5252T engine

  • This is a fairly resourceful diesel engine with direct injection and a reliable high-pressure fuel pump Bosch VE37;
  • The main thing here is to monitor the cooling system, since the cylinder head is very afraid of overheating;
  • Once every 120,000 km, an expensive replacement of the timing belt awaits you, and if it breaks, the valves will bend;
  • The turbine runs well here, but the boost control valve often fails;
  • The weak points of the engine include a vacuum pump and a mass air flow sensor.
