Fuel System
(SYMPTOM 17) SMOKES (BLACK, WHITE, BLUE) WHEN ACCELERATING
• Compensation of individual injector not adapted
• Clogged air filter
• Bad fuel quality or water ingress in fuel
• Oil level too high or too low
• Damaged turbocharger
• Oil suction (engine racing)
• Faulty air heater
• Low compression pressure
• Leakage in high pressure fuel circuit
• Intermittent faulty fuel line connection
(SYMPTOM 18) FUEL SMELLS
• Not connected fuel feed line
• Not connected fuel return line at injector
• Leakage at the Fuel pressure regulator valve
(SYMPTOM 19) THE ENGINE COLLAPSES AT TAKE
• Blocked accelerator pedal position sensor
• Incorrect state of the electrical pack devices
• Clogged air filter
• Inversion of fuel connections (feed ＆ return)
• Faulty fuel filter
• Bad fuel quality or water ingress in fuel
• Air ingress in the low pressure fuel circuit
• Clogged fuel filter
• Intermittent faulty fuel line connection
(SYMPTOM 20) ENGINE DOES NOT STOP
• Stuck or worn lubrication circuit of turbocharger
• Too much engine oil
(SYMPTOM 21) DIFFERENT MECHANICAL NOISES
