8.6.2. Check and clean injectors (37)
For the engine to produce full power the injectors

should be carried out by an authorized workshop.
Symptoms of dirty or defective injectors:
- Knocking indicates a fault on one or more of the
injectors. Knocking can occur on a cold engine
when running at idling speed. When knocking
occurs at normal working temperature this indicates
that the injectors are not functioning property.
- Air in the fuel system can also cause knocking
(disappears after the system has been bled).
- Smoked exhaust gases are another symptom of
poor function of the injectors (can also be due to
other reasons, e.g. blocked air cleaner).
