I have read of a lot of folks getting their water pump replaced to solve this and it comes back needing the headgasket….the dealers aren't diagnosing this correctly for lots of people which is crazy to me. I know VW has to have a TSB out on this so they should be well aware when an Atlas comes in for low coolant that it *could * be the headgasket.The dealer has already replaced my water pump due to the same issue saying there was a small crack in some adapter. This was about 5-6000 miles ago. It is currently sending the same error message with the low coolant leak, so here we go again!!
