Is it necessary to clean carbon deposits in Audi engines?
2 Answers
Audi engine carbon deposits require cleaning. Here are the specific details: 1. Formation of carbon deposits: Cars must convert fuel combustion into kinetic energy, so carbon deposits will form within just ten seconds of fuel burning in the cylinders. 2. Hazards of carbon deposits: The formation of carbon deposits during long-term engine operation is a normal phenomenon. If you notice idle shaking that returns to normal after the water temperature rises, this may be caused by carbon deposits. In such cases, an endoscope can be used for inspection. Excessive carbon deposits can also lead to sluggish acceleration because the deposits occupy cylinder volume, preventing the piston from functioning properly and resulting in reduced power. 3. Cleaning carbon deposits: There are two main methods for cleaning: chemical cleaning and physical cleaning. Chemical cleaning can be somewhat effective for mild carbon deposits, but it should be used with caution. For more severe carbon deposits, the only solution is to disassemble and clean with tools, which is both safe and thorough.
As a long-time Audi driver, I believe cleaning engine carbon deposits is quite necessary. Carbon deposits are sludge buildup inside the engine, especially in Audi's turbocharged models which are more prone to formation when frequently driven at low RPMs in urban areas. Over time, this can lead to increased fuel consumption, reduced power output, and noticeable engine vibration while driving. My own Audi A4 was neglected before, resulting in unstable idle after 100,000 km. The dealership quoted over 1,000 RMB for cleaning, but the difference afterward was remarkable - acceleration became smoother. I recommend checking every 20,000 km, particularly if using 92-octane fuel or having an aggressive driving style with frequent hard acceleration, as these accelerate carbon buildup. The cleaning process is simple nowadays, with many repair shops offering specialized detergents for a few hundred RMB, preventing the risk of major overhauls. Overall, prevention is more cost-effective than repairs - don't wait until problems escalate.
