Disadvantages of the QXWA/QXWB engine

  • On engines of the first years of production, the chain between the camshafts was often stretched;
  • Fuel equipment with piezo injectors is very picky about fuel quality;
  • Hydraulic lifters do not tolerate low-quality oil and can knock even up to 100,000 km;
  • Due to the vibrations of the motor, the wiring is often frayed and the ECU starts to pour errors;
  • As always, a lot of problems are thrown to the owners by a particulate filter and an EGR valve.
