I have a 02 Audi, A4, Quarttro 3.0, V6, 98K miles

When I pressed the check button, couple indicator symbol comes up, they're the following:

Coolant temperature and level---the symbol is moving, what does this indicate, I just check the coolant, and it has enough, but I don't know why the indicator light is on.

Oil pressure----What does this indicate? Does it mean that I have low oil, or I just have to changed the engine oil?

Brake pads worn light--this light is not red, I don't know if they suggest me to change it, or there's something wrong with it.

 

is it running thru all the checks, mine does the same thing, does it say ok at the very end and does it show the gas pump and window washer fluid, the pictures of the coolant and oil are annimated. if it says ok at the end you should be ok, if it is a real problem the cel will come on, mine does the same thing right after an oil change from the dealer.

 

Yeah, it say OK in the end. If there's no problem, but why do those light come on then when press the check button.

 

sometimes if like one of your fog lights is out or something, it wont singal you everytime you turn on the car... if you press that, it does a system check and if say you had a fog light that was out, it would show up on there... just like a backup check thing

 

What what do you mean?

 

if you have a bulb out or something wrong with the car you know and everybody else that the car will let you know and not go away until you fix it, I have a taillight out right now and it tells me everytime I turn the car on, the check button is doing a quick system check to make sure everything is ok, I never push that button anymore because another light will come on and tell something is wrong, btw don't push the button next to it, I think it has the wrench on it while you are driving, you will set the speed limiter so however fast you are going the car will alarm at you, pissed me of for a couple of days. your car is fine, it will tell when its not
