light white smoke
 

I have light white smoke coming from my exhaust pipe. could it be that i need a new oil change or a more serious problem.

Assuming you don't live in a cold place and it's warm there and whether or not be causing you to see the exhaust. sorry I just had to say it... white smoke out of the exhaust usually means burning coolent or oil. Which usually means head gasket issue. Now that's just based off what you said. I wouldn't get to alarmed unless your car is overheating out of the blue but it is something you could look into. You can do a compression test and keep an eye on your fluids. I think like almost every Audi has coolant in oil level sensors. So those two were alert you when you get like really low so you won't be totally clueless if something is happening.
