— official information
There are no particularly specific problems with the motor version of the N53. Its main problems are the lifetime of the high-pressure fuel pump, which does not exceed one hundred thousand kilometers, spark plugs that work no longer than ten thousand km, often failing ignition coils (operated about 50 thousand km) and serving no longer than 100 thousand km high pressure nozzles.
Among the main measures for the prevention of engine breakdowns during operation, one can single out: monitoring the cooling system, inspection and regular cleaning of the radiator – to prevent its overheating, and constant monitoring of the quality of the oils and gasoline poured in. Compared to the N52B25, this modification of the unit has a better overall resource and no problems associated with increased oil consumption.
