What does it mean when the car displays EDC?

[ElianaAnn]

When the car shows an EDC fault warning, it indicates a malfunction in the car's high-pressure electronic injection and electronic control system. Here is extended information about the EDC fault in cars: 1. Odor in the engine compartment: 1.1. Caused by burnt or melted wires around the engine. 1.2. Due to the use of a large amount of lubricating grease during maintenance, which produces an odor when the temperature rises. 2. Increased lubricant consumption: 2.1. Decreased sealing of the engine piston, leading to increased clearance between the piston and cylinder wall. 2.2. Severe wear of internal engine components, resulting in larger gaps between parts. 2.3. Poor quality lubricant leads to increased consumption. 3. Severe engine carbon deposits: Carbon deposits form during the engine combustion process.
