Aston Martin engine system is in urgent need of maintenance. What caused the fault light to come on?

The reasons why the engine fault indicator light is on are: 1, poor gasoline quality will lead to insufficient combustion of the mixture in the cylinder; 2. Carbon deposition in the air inlet and piston will lead to poor atomization and insufficient combustion; 3, the spark plug is not changed for a long time, and the working characteristics are weakened; 4, car sensor failure.
