What faults occur in the Lynk & Co 05?

The faults that occur in the Lynk & Co 05 are as follows: 1. Poor idle operation may manifest as unstable idling, engine shaking, excessively high idle speed exceeding the specified upper limit, excessively low idle speed below the specified lower limit, or rough idling. These phenomena are related to faults or poor performance of components such as the fuel injector, oxygen sensor, air flow sensor, exhaust gas recirculation valve, as well as issues with control circuits or poor connections in vacuum lines. 2. Abnormal exhaust pipe smoke includes black smoke, white smoke, and blue smoke. Black smoke indicates an overly rich air-fuel mixture, related to defects in the fuel supply, air distribution, mechanical, or electronic control systems; white smoke suggests high water content in the fuel; blue smoke indicates engine oil burning.

What causes the sluggish acceleration in BMW e90?

The car's small displacement and heavy load can lead to weak acceleration during startup. Cold start: During a cold start, even if you press the accelerator deeply, the car accelerates very slowly. This improves after the engine warms up. This is a protective mechanism for the transmission and engine, common in many car models. In a cold state, the lubricating oil hasn't fully circulated to all components, and sudden acceleration can cause severe wear on the transmission and engine. Small displacement: If the car has a small displacement and carries a heavy load, it may experience weak acceleration during startup. For example, if you usually drive alone but suddenly have five passengers, you'll noticeably feel the lack of power. There are many potential causes for such issues, including poor valve sealing leading to insufficient cylinder pressure, excessive carbon buildup in the intake manifold, or spark plug carbon deposits or incorrect gap settings.
