    I've recently bought a 2002 A4 Quattro 2.5 tdi.
    Just noticed today that when I switch my ignition on, the check engine light does not light up, and now I am quite worried that somebody has removed the bulb!
    Can anybody tell me wether it should light up or not?
    Is there a way I can safely make the light come on to make sure the bulb is there?
    Many thanks in advance
    Chris :unsure:

    Uh Oh!
    Is there any way to check there is a bulb there without taking the clocks out?

    Yes the rest of the lights work, glowplugs etc. My DIS also works, as does the check function. It's just worrying that my engine light does not light up. I have unplugged my MAF and started the car, and on idle it still does not light up.
    I think I may be in trouble here. Any suggestions?

    What do you mean by the "check engine" light?

    Sorry. By check engine light, I mean the light shaped like an engine.
    Engine management light

    Just looking through my manual, and all the other lights for abs, glow plugs etc state that they light up when the ignition is switched on, but it does not say that for the engine management light.
    Embarrassingly, it looks like I am crapping myself for no reason.

    The orange one shaped like a car with a key underneath it?

    Mines comes on for a couple of seconds with the ignition and then goes out.

    I know exactly how you feel. I probably spend lots of money changing stuff just so it doesn't, even tho it more than likely doesn't need changing.

    It's not just me then. I've been exactly the same with most of the cars I've had.

    Hmmmm....are you all sure? I'm pretty certain it should illuminate when you turn on the ignition. I don't mean start the engine, just when you turn the key to the first point. All the dash board lights come on, including the EML. Have tried it on mine and it lights up and then goes out when the engine starts. Don't know if it differs depending on age and fuel type maybe? Mine is an 02 plate petrol.

    Sorry to throw a spanner in the works :ermm:

    Mine does but mines a 1.8t so maybe different. But comes on and goes off as it does on most cars.

    Perhaps one of you can take a picture of the light when it's illuminated so we know we're all talking about the same thing!

    guys - that sounds like the immobiliser light: I've got a spare set of keys that's not coded and that light stays on when I try turning the engine over with the "duff" key in there.

    It takes a second or two to verify the coding and turn the light off...

    So far, everybody with a diesel doesn't have it come on, and everyone with a petrol does

    This is why I asked for a photo. I mentioned this earlier in the thread and it's not the engine management light.
