What owners say
(1) events leading up to the failure: none--I've been experiencing a coolant leak since day one. Only recently has it gotten worse and now I see that there is water in my coolant. (2) failure and its consequences - coolant in oil causes premature damage of engine components (bearings, turbos). New engine costs exceed $15,000. New turbos costs exceed $5,000. This problem is posted all over audiworld.com. Multiple people have had the oil checked and determine that high levels of copper (caused by coolant) were in the oil and would result in near-term engine/turbo failure. (3) what was done to attempt to fix the problem: (a) coolant system checked three times by audi service at my cost and they have not been able to determine the problem. Costs so far exceed dollars with no fix in sight; (b) water-pump replaced ; (c) secondary water-pump replaced I am about to pay $2000 to get the head-gaskets replaced. Unfortunately this is a maybe fix since the problem cannot get diagnosed. Multiple people have posted on audiworld that they have had the same job completed with no benefits to the problem.
