Is the Ford Mondeo's turbocharger prone to failure?

The Ford Mondeo's turbocharger is not a wear-prone component, so it is not easily damaged. The turbocharger works by utilizing the high-temperature exhaust gases from the engine, which range between 700-900 degrees Celsius, to drive the turbine wheel inside the turbo. The turbine shaft then spins the compressor wheel at high speeds, compressing air in a centrifugal manner to increase the engine's intake air density to 2-3 atmospheres. Symptoms of a damaged turbocharger include: 1. During rapid acceleration, a high-pitched scream from the exhaust valve can be heard above 1750 RPM; 2. Abnormal noises from the turbo's damaged parts when the car's odometer is checked; 3. If the car's turbocharger is damaged, the engine warning light will illuminate; 4. It can lead to incomplete combustion within the engine, resulting in strong exhaust odors.

I've been driving this Mondeo 2.0T for almost five years, and the turbocharger has been performing great. People say it's prone to failure, but it really depends on maintenance habits. From what I've learned from experienced owners, there are two main points to pay attention to: first, the engine oil must be changed on time, with full synthetic oil being replaced every 5,000 kilometers for the best reliability; second, don't turn off the engine immediately after high-speed driving—let it idle for a minute to cool the turbo. Avoid sudden acceleration in daily driving, especially during cold starts. The turbo bearings wear out quickly if they lack lubrication. Last time during maintenance, the mechanic mentioned that most turbocharger failures they see in the shop are caused by expired oil or clogged oil passages. This generation of Mondeo is actually much more durable than the older models.
