Using the diagnostic matrix the type and extent of damage can be easily identified. So we can faster and cheaper repair your car, thus avoiding breaking of the engine to turn into a serious problem.
Defects in turbine or compressor wheel
Възможна причина:
Failure in turbocharger bearings Damages caused by foreign objects in the turbine or compressor wheel Failure in turbine or valve casing Insufficient oil feed of the turbocharger
Lack of power, low charging pressure
Possible reasons:
Contaminated air filter
Replace the air filter according to the engine manufacturer's instructions.
Deformed or unsealed installations for pressure and vacuum Gas bleed-off system has too much resistance Defect in the fuel system (nozzles, pump) Wear engine (valves rubber seals and guides, segments and cylinders) Contamination of the turbocharger air cooler Defect in the control valve (does not close) Defect faucet of control valve Failure in turbocharger bearings Failures, caused by foreign objects in the turbine or compressor wheel Leak engine air scoop, lacking or loose seals Damage in the turbine housing or valve Insufficient oil feed of the turbocharger
Too high charging pressure
Possible reasons:
Defect in the fuel system (nozzles, pump)
Defect in the control valve (does not open)
Defect faucet of control valve
Black smoke from the exhaust pipe
Possible reasons:
Contaminated air filter – Replace the air filter according to the instructions of the engine manufacturer
Deformed or unsealed installations for pressure and vacuum
Gas bleed-off system has too much resistance Defect in the fuel system (nozzles, pump) Wear engine (valves rubber seals and guides, segments and cylinders) Contamination of the turbocharger air cooler Failure in turbocharger bearings Failures, caused by foreign objects in the turbine or compressor wheel Leak engine air scoop, lacking or loose seals Damage in the turbine housing or valve Insufficient oil feed of the turbocharger
Bluish smoke from the exhaust pipe
Possible reasons:
Contaminated air filter – Replace the air filter according to the instructions of the engine manufacturer Gas bleed-off system has too much resistance
Oil system is clogged, unsealed or deformed Engine case ventilation is clogged or deformed Turbocharger bearing housing is contaminated and clogged Wear engine (valves rubber seals and guides, segments and cylinders) Contamination of the turbocharger air cooler Worn segments Failure in turbocharger bearings
Turbocharger produces sounds and noise
Possible reasons:
Deformed or unsealed installations for pressure and vacuum
Gas bleed-off system has too much resistance Contamination of the turbocharger air cooler Failure in turbocharger bearings Failures, caused by foreign objects in the turbine or compressor wheel Gases leakage between the exhaust pipe and turbine outlet Leak engine air scoop, lacking or loose seals Damage in the turbine housing or valve Insufficient oil feed of the turbocharger
Possible reasons:
Contaminated air filter – Replace the air filter according to the instructions of the engine manufacturer
Gas bleed-off system has too much resistance Oil system is clogged, unsealed or deformed Engine case ventilation is clogged or deformed Turbocharger bearing housing is contaminated and clogged Wear engine (valves rubber seals and guides, segments and cylinders) Contamination of the turbocharger air cooler Worn segments Failure in turbocharger bearings
Leakage of oil from compressor wheel
Possible reasons:
Contaminated air filter – Replace the air filter according to the instructions of the engine manufacturer
Gas bleed-off system has too much resistance
Oil system is clogged, unsealed or deformed Engine case ventilation is clogged or deformed Turbocharger bearing housing is contaminated and clogged Wear engine (valves rubber seals and guides, segments and cylinders) Contamination of the turbocharger air cooler Worn segments Failure in turbocharger bearings
Oil leakage from the turbine
Possible reasons:
Oil system is clogged, unsealed or deformed Engine case ventilation is clogged or deformed Turbocharger bearing housing is contaminated and clogged Wear engine (valves rubber seals and guides, segments and cylinders) Worn segments Failure in turbocharger bearings
