Consumer Description
The water pump on my 2016 Audi A6 has failed multiple times prematurely. The first water pump failed at 36,965 miles in May 2019. That repair was covered under an extended warranty I purchased. The second water pump failed around 83,000 miles in September 2025, and Audi is now quoting me $2,350 out of pocket to replace it. I am now facing a third water pump replacement, which is far earlier than expected for this type of component. These repeated failures create a significant safety concern, as sudden coolant loss can cause the engine to overheat, potentially leading to engine failure or loss of power while driving. Each problem has been diagnosed and confirmed by an authorized Audi service center. The vehicle was inspected by Audi technicians, and repairs were recommended both times. The repeated failure of this critical component strongly suggests a systemic defect with the water pump design on this model. Despite a recent Audi water pump settlement, my vehicle was excluded, even though it has now experienced two failures and is requiring a third replacement.
