Has anyone experienced problems with their S4 losing antifreeze or for that matter losing oil; but it not leaking out onto the ground, in other words what appears to be an internal leak?
I hate to assume the worst, that I have warped block, or a cracked head, or a cracked block, and would even hope that it is just a leaky head gasket.
Any of the above is not good.
Has anybody had an issue like this, and what did Audi do for you? What tests did you request? A cylinder leak-down test? Did you have to request a new engine? How did Audi treat you? How did the dealer treat you?
