After just getting a $500 quote from the VW dealer to service my DSG and replace my fuel filter, I am thinking I should just get the equipment and do it myself. I have read the article and was going to attempt the measure/refill method with a top fill. The instructions state to install the snorkel and then the oil pan plug. Is the snorkel already in my transmission or is it something I need to purchase? Sorry for the silly question, but I have always had it serviced and want to make sure I have everything needed before I tear it apart. Any other tips of wisdom?
