    Default Engine Diagnostics warning light

    2013 3 litre V6 Coupe. This has been on permanently for four years. On start up Anti pollution warning comes on. Have changed sensors and reset multiple times. Twenty four hours later warning light back on. Has anyone had experience with this problem please. How to fix?

    What sort of car is it? And what are the codes you keep clearing?

    My 2002 manual coupe does exactly the same thing. I just ignore it as it doesn't have any effect on the running or performance of the car!

    As a matter of interest - which sensors did you replace?

    I realise that but its not a good look if you try top sell it! Changed exhaust upstream oxygen sensors on front and rear banks.

    If you have successfully ignored the lamp for 4 years, one option is to simply remove the lamp entirely.

    Alternatively have the car's Ecu connected diagnostic equipment and find out where the problem lies.

    The former is likely the cheapest option.

    Alright in that case I think the year might be wrong.
