Disadvantages of the HR12DDR engine
- This is a reliable motor and the main complaints on the forums are related to noise and vibrations;
- The compressor runs for a long time if the lubricant is changed in it, but sometimes its pipe bursts;
- Like all direct-injection engines, intake valves quickly overgrow with soot;
- The weak points of the unit also include the ignition unit relay, catalyst and mass air flow sensor;
- Do not forget about adjusting the thermal clearance of the valves, there are no hydraulic lifters here.
