Hi again, I unplugged the airflow meter as you suggested, and found that the car ran unevenly this from what you say seems to indicate that the airflow meter is o k ? unfortunetely the engine management light is now staying on and as I am just about to take the car for its M O T ,
I beleive that this will cause it to fail ? Can you tell me how to get it to turn off ?
Hello, Thanks for your reply, I have tried what you suggested, unfortunetely, the light has remained on, and every time I start the engine, a bright warning light comes on, indicating an engine fault,
have you any suggestions on this further problem and how to
irradicate it ?
You can also try resetting the car by removing both battery leads and clamping them together for 10 mins as this will reset everything so if the light re-appears then the fault is still there.
Disconnect the battery cables and clamp them together for 10 mins. Remove both battery leads from the battery then use a nut and bolt or G-clamp to hold both battery lead terminals together.
This discharges any capacitors / memory within the ECU and around the car so ensures all memory settings are wiped clear - back to the factory default.
This will reset all the systems on the car and you may need the radio security code to get it going again, and ensure that the keys are in your hand when you re-connect the battery as the car may lock and turn on the alarm
