glow? do you mean light bulb? - if so look for a exterior light out and replace bulb

That is probably a water temp warning light,or oil pressure waring light

i have a light that comes on my audi a3 1.8t dash board .it is round with a cross through it and like a little box on top can any one tell me wat this is thanks

if it is the lower left corner then that is a coolant warning

is this your dash?

Not sure from your description but this sounds like your traction warning light (left side of the warning light panel, it looks like a triangle with an arrow going round it in a circle), it normally comes on when you have either turned the traction control off via the button on the dash or if its wet on the road. It can also be caused by cornering too fast.

Malfunction indicator light it is the symbol of your engine with a line of suffering and the word "CHECK" -- this could be something minor like needing a spark plug to be replaced (common problem) or to something more serious like engine electrical work needed. a flashing engine light is the more serious so you are not to worry.

this is not really a warning light but works similar it is telling you about other problems that they are not related to computer or engine problems it can be a burn brake light bulb it can be oil change or maybe your washer fluid is low things like this can trigger this symbol so look for any small detail and in your user manual it tell you how to reset this light and turn it off

you water level in your windscreen washer bottle is low check all water levels it is go practice to check all water and oil levels once a week
