Disadvantages of the KR15DDT engine
- This turbo engine has just appeared and the statistics of its malfunctions have not yet been collected;
- So far, on specialized forums, they only complain about frequent glitches of the Start-Stop system;
- The intake valves here are quickly overgrown with soot due to the direct injection system;
- There are no hydraulic lifters and valve clearances need to be adjusted every 100,000 km;
- And the main problem of the engine is where to fix the compression ratio system.
