    If you turn the ignition on and wait (before starting the engine) do the lights go off?

    I think you are OK if they all go out when the engine is started. All the warning lights come on when the ignition is switched on so that you could tell if a bulb had blown (if the bulb for engine warning had blown for example you would never know if it was actually trying to show you a fault unless you noticed it didn't light up when the ignition is switched on. With my car the warning lights come on but then switch off but it has virtual cockpit.

    I've looked on YouTube they all gone on but go out. My EPC and check engine only go out when I start the engine.

    Strange I never picked up on it before but clips on YouTube they come on with ignition on and off with ignition on. Mine go out with engine started.

    If there off once the engine is started and there not displayed whilst the car is running etc then all is well.

    I had a boost issue and when the problem arised EPC light came on and stayed on until the engine was re-started. It continued until I sorted the problem.
