I havent had much luck in A4 area, so myabe you guys can help me out. As of late my coolant has been mysteriously vanishing, with no leaking around the car. I had my first incident with the coolant light coming on when I was getting on it on the high (about 100 MPH) and then it went off in about 1-2 mins after i slowed down. The level was abotu 1 inch below LOW pt. On top of that I still have egr issues, and its not the EGR. I have two hoses not connected to anything and I can put up some pictures if that would help. Any ideas on wtf is going on?

 

pictures will help also any fault codes/engine type/age of car

 

I had that problem in a 7 series bmw.. what was happenening was i had a small leak and the coolant was falling onto a hot pipe, i think it was my exhaust, and burning up there so there was no evidence of a leak on the ground. So, if you have any of those plastic covers for the bottom of your car or when you get out and listen and you hear somewhat of a sizzle that could be it... other than that idk

 

Look below the timing cover you could havewater pump leaking. I have seen them not drip but dry up and make long crystal like shapes at the bottum....
