What are the symptoms of a broken car turbocharger?

[PeterLee]

Turbocharger failure can lead to symptoms such as engine weakness, black smoke from the exhaust pipe, oil burning, and insufficient oil. If the turbocharger is broken, you should not continue driving. If the turbocharger's sealing ring is damaged, exhaust gases can enter the engine lubrication system through the sealing ring, contaminating the oil and rapidly increasing the crankcase pressure, resulting in excessive oil consumption and oil burning. Relevant information about turbochargers is as follows: 1. Turbocharger: A piston-type aircraft engine uses a device to increase the intake pressure in the cylinders. Before entering the engine cylinders, the air is compressed by the turbocharger to increase its density, allowing more air to fill the cylinders and thereby increasing engine power. Engines equipped with turbochargers can not only output greater takeoff power but also improve their altitude characteristics. 2. Automotive turbocharger: Turbocharging is a technology that compresses air before supplying it to the cylinders to increase air density and intake volume. The purpose is to increase air intake, enhance power, improve fuel economy, and reduce emissions.

After the supercharger fails, the symptoms are quite obvious. The first thing I noticed was a drop in power during acceleration. Previously, a quick press on the gas pedal was enough to overtake, but now the car feels like it's being dragged, struggling even on small slopes. There's also abnormal noise—sharp whistling or rattling sounds frequently coming from the engine bay, especially at high speeds, which might be caused by bearing wear or oil passage blockage. Fuel consumption has suddenly increased too. Last month, a full tank could last 500 kilometers, but now the low-fuel light comes on before 400, as the engine has to work harder due to the supercharger failure. Occasionally, black smoke comes out of the exhaust pipe, a sign of incomplete fuel combustion. The dashboard also lit up the supercharger warning light—don’t ignore this issue, or the engine could be damaged, leading to even higher repair costs. It’s recommended to visit a professional shop for inspection immediately. Regular maintenance of the turbo system, ensuring clean oil and unobstructed filters, can prevent problems before they occur.

As a frequent driver, I've personally experienced supercharger failure symptoms. First, the acceleration became slower, and when overtaking on the highway, the car felt completely powerless, as if being held back, with particularly sluggish acceleration. The fuel consumption issue is also quite annoying. Previously, the average consumption in the city was 8 liters per 100 kilometers, but now it's jumped to over 10 liters, leading to more frequent refueling and significantly increased costs. In terms of noise, I hear strange sounds while driving, like a whistling wind or rattling, especially noticeable during hard acceleration. Occasionally, black smoke comes out of the exhaust pipe, and the dashboard lights up with that wavy warning light. If this problem isn't addressed early, the engine may overheat or even break down on the highway. I suggest getting it checked out soon rather than waiting until it gets worse. It might just need replacing the turbo components or a simple cleaning of the fuel system.

The supercharger is broken, and the symptoms significantly affect performance. What annoys me the most is the power loss—the complete absence of that push-back feeling during straight-line acceleration, making the car feel sluggish and slow to start at traffic lights. In terms of noise, there's a sharp, high-pitched sound at high RPMs, resembling metal scraping, which is particularly grating on the highway. Fuel consumption has also increased, with the tank emptying quickly after a drive, which is really frustrating. If the dashboard shows a turbo warning light, it's a clear signal. Such issues must be taken seriously, especially since turbo failure can cause a chain reaction damaging the engine.
