It is recommended to install the high-pressure fuel lines onto
the engine only once. repeated installation will not ensure the
secure sealing of joints and long-term fuel line operation.
High-pressure fuel pump (HPfP).
The HPFP and orifices maintenance, adjustment, inspection
and repair are recommended to be carried out in BOSCH
service centers. Independent adjustment, partial or complete
disassembling of the HPFP is not allowed.
ATTenTIon!
It is prohibited to unscrew the central fastening
nut of the HPFP pulley hub and to remove the HPFP pulley with the

Engine".
Turbocharger
To prevent turbocharger damage, the engine may not be
operated without the air filter or with the air filter damaged.
If the engine is operated with the recommended lubricating
oils, the TCR service life is the same as that of the engine.
ATTenTIon!
When the engine is stopped after long-term
operation at high rpm or high load, you must let the engine run at
idle minimum rpm for 3-5 minutes, to prevent the premature failure
of the turbocharger.
ATTenTIon!
Do not allow the engine to run at idle minimum
rpm for more than 10 minutes, since due to negative pressure
created by the cylinder-piston group, the air pressure inside the
turbocharger housing is established below the atmospheric pressure.
Some lubricating oil from the housing of turbocharger bearings,
through the wheel labyrinth seal, enters the engine inlet system,
leading to its increased smoking.
To avoid the engine failure, it is strongly prohibited to adjust
the TCR bleed valve.
You may not adjust the turbocharger pneumatic chamber
rod length using the nut. The rod length is strictly tuned by the
manufacturer of turbochargers and modifying its length will lead
