    Hi all,
    wondering if someone can give me some advice please?
    I have an Audi A4 Diesel 2011
    Once i switch on the Ingnition the Emission Control Warning light comes on, on the dashboard.
    Once i start the engine, the Emission Control light goes off.
    So just wondering if this is something that i should get checked or is it just a matter of the Dashboard displaying on ignition that the control light works?

    Many thanks!

    I wouldn't worry about it. Turning on the ignition activates the electrical system on the car, including engine sensors. Once the car is started - if it goes out it's fine. If someone close to you has a copy of VCDS you can get the car scanned if that gives you peace of mind.

    Diesels need to be used, so if you've had a long run and hear the DPF regeneration, then all is good.
