Hi, could ask if someone could tell me how long it takes to check the transaxle oil and the air vent line in an i30?  I am curious as I was charged nearly $250 to have these two items checked by a dealer on the north coast of NSW.  It doesn't sound right.  Thanks for any insight anyone might have.

So we can help out a bit could you give some vehicle info please. Year and auto or manual at least.

Also what do you mean by air vent line?
