This is a reliable motor and the main complaints on the forum 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 DMRV
Do not forget about adjusting the thermal clearance of the valves, there are no hydraulic lifters here
