What does it mean when the xc60 displays reduced engine performance?

[DelKai]

xc60 displaying reduced engine performance indicates a damaged turbocharger. Symptoms of a damaged turbocharger include the following: 1. Exhaust pipe: Blue or white smoke from the exhaust pipe. 2. Power: Noticeable decrease in power. 3. Fuel consumption issue: Increased fuel consumption. 4. Oil consumption: Increased oil consumption. 5. Turbocharger pressure issue: Unstable turbo pressure. Additional information: Causes of turbocharger failure: 1. Insufficient lubricating oil pressure and flow. 2. Debris or dirt entering the lubrication system, causing oil oxidation and deterioration. 3. Excessive wear of turbocharger rotor bearings or thrust bearings; high-speed rotation of the turbocharger rotor. 4. Blocked turbocharger oil return pipe, leading to excessive oil accumulation in the intermediate support of the rotor assembly, which then flows along the rotor shaft into the compressor impeller.
