Vehicle has not even reach 92k miles and the waterpump is a already failing. Audi this is a know issue but the remedy has not been fixed. They only way to fix this is to replace with new unit. I understand Audi specifically made a "weep" hole to warn the owner before the whole unit fails. This causes coolant to leak which eventually gives you the low coolant level warning on the dash. This is to prevent the bearing inside the waterpump to completely fail causing metal to metal contact thus causing specs of metal inside your coolant systems. It's unfortunate that this failing earlier than anticipated considering vehicle has not even reach the 100k miles.
