Reasons for the EA888 engine reporting a too rich system in cylinder 1: 1. Issues with the air flow sensor. 2. Not all air passing through the air flow sensor enters the cylinder, some leaks outside the closed system. 3. Damage to the control unit. Below is an introduction to the EA888 engine: 1. The EA888 is a large series with many different engine models, such as CWN, DKU, DKW, etc. The 330TSI engine is the EA888 third-generation B (commonly known as 3.5 generation) engine, while the 380TSI engine is the EA888 third-generation engine. The 3.5 generation engine is superior to the 3rd generation engine, meaning the 2.0T low-power engine is better than the 2.0T high-power engine. 2. The internal forging of the 2.0T low-power engine is different, leading to variations in the strength of certain engine components, such as the crankshaft. The 330TSI is equipped with a 2.0T inline 4-cylinder turbocharged low-power engine, paired with a 7-speed dual-clutch transmission, delivering a maximum power of 137KW and maximum torque of 320N·m. The 380TSI is equipped with a 2.0T inline 4-cylinder turbocharged high-power engine, also paired with a 7-speed dual-clutch transmission, delivering a maximum power of 162KW and maximum torque of 350N·m.

Is It Necessary to Clean the Intake System?

It is necessary to clean the intake system. Since there is currently no complete method to prevent carbon deposits, if not cleaned regularly, carbon deposits will accumulate endlessly. Once carbon deposits build up in the intake system, it can cause issues such as engine shaking and reduced power in mild cases, and in severe cases, it may even lead to engine cylinder scoring or seizure. There are generally two cleaning methods for the intake tract: drip cleaning and disassembly cleaning. The intake system consists of components such as the air filter, air flow meter, intake pressure sensor, throttle body, auxiliary air valve, idle control valve, resonance chamber, power chamber, and intake manifold.
