My coolant started running almost dry. The light just came on for the 2nd time in a month and when I checked the coolant, it was very low. I took it to the dealer Sept 29th and had the oil changed and coolant filled. They told me it was burn off from running the A/C. That nothing mechanically was wrong (VW dealership) It has only been 750 miles and there is no noticable leak and it is low and the light came on again. Could this be a very bad thing or an easy fix? Is it going to be expensive? My warrant ran out Sept 30th...so it is either out of pocket or a huge fight to get it fixed.
