Golf 6 exhaust system failure light is what reason
This is normal, I also like this! There is no problem.
First check the front and rear oxygen sensor, this thing is bad The initial appearance shown in the instrument shows the engine exhaust system failure light long (or occasionally flashing), but the short car can barely driving; long time not repair, will make The electronic fuel injection system computer (ECU) can not get the oxygen concentration of the exhaust pipe information, and therefore can not feedback control of the air-fuel ratio, will make the engine fuel consumption and exhaust pollution increases, the engine idling instability, lack of fire, And other symptoms. Therefore, the failure or replacement must be eliminated in a timely manner.
