Age and wear and tear — as you would expect, a turbo will not last forever. It will need replacing eventually. Other issues — as the turbocharger is constantly under pressure, there are many things that can impact its performance.
Excessive exhaust gas temperature EGT can overheat the part, and moisture ingress can cause rust and degradation. Additionally the turbo can suffer from problems caused by the exhaust system, the fuel intake and the waste gate. Loss of power and slow acceleration — the turbocharger is designed to make your car reach top speeds faster.

As the fault gets more serious, the noise will get worse.
If you notice a whining from your engine, you should get a professional mechanic to have a look at your car. This could be caused by a crack in the turbo housing or damaged internal seals. If this symptom is caused by the turbocharger, you're more likely to see these discoloured fumes as the engine revs increase shortly after idling. The computer diagnostics on most modern cars are able to pick up turbo faults and the check engine light will appear on the dashboard to notify the driver.
However, the check engine light doesn't solely indicate turbo failure - you will need a professional mechanic to perform further checks to diagnose the exact nature of the engine problem. Turbochargers are extremely reliable.
