It is frequently necessary to clean the injector and replace the gasket in the monoinjection system. The owner is also bothered by frequent failures in the electrical part. It does not have a long service life, and the timing chain is replaced at 150-200 thousand km. Furthermore, this unit is plagued by constant oil leaks through gaskets and seals.
