What are the symptoms of a broken turbocharger?
2 Answers
When the engine turbocharger is broken, the following symptoms may occur: 1. Decreased vehicle power. 2. Incomplete fuel combustion. 3. Severe carbon buildup in the engine. 4. Increased fuel consumption. 5. Blue or black smoke from the exhaust pipe. 6. Engine shaking. 7. Harsh noises during sudden acceleration. Below is extended information on the causes of engine turbocharger damage: 1. Blue smoke during driving or acceleration indicates poor sealing of the turbocharger impeller shaft. 2. Increased fuel or oil consumption suggests severe blockage in the engine's exhaust gas recirculation pipe. 3. Abnormal engine noises during driving may be due to worn or aged piston rings, cylinder walls, or valve seals. 4. Abnormal noises during throttle application or release could indicate a cracked turbocharger air duct.
The most obvious sign of a broken turbo while driving is a severe drop in power. When you press the accelerator, the car accelerates very slowly, as if the engine is struggling. Climbing hills or overtaking at high speeds becomes particularly difficult. The noise level also increases—you may hear sharp hissing or whining sounds, sometimes coming from under the car. The exhaust smoke may appear abnormal in color, such as blue or white smoke, accompanied by a burning oil smell, as failed turbo seals allow oil to leak into the exhaust system. Fuel consumption becomes much higher than usual, and the engine bears extra strain, possibly triggering the check engine light. If left unrepaired for a long time, it can damage the entire engine. I believe you should visit a professional repair shop as soon as you notice these symptoms to avoid further costly repairs.
