My car leaked a large amount of coolant noticed after it had been parked. I managed to drive it to dealer where the water pump was replaced under warranty. I was told that the plastic seal on the pump has failed with other customers and was replaced with a new metal seal.

2010 audi s4 water pump failure.
2010 audi s4 water pump failure -- this complaint is identical to the previous two complaints surrounding this model's water pump failure. It should be noted that a near full loss of steering directly related to this failure occurred at the same time. In my case the car has been repaired, however like others who have detailed their experiences, audi has not acknowledged this is a systemic issue for this model, nor is the repair satisfactory as the distinct odor of g-12 (g-30 in europe) is present. Though this is a safety issue first, it is also a consumer protection matter as the both the dealer and audi of america who I have been in communications with has not been clear about this issue.
This has been a known issue to many 2010 audi s4 owners. Many of them reported a waterpump failure basically under any circumstances, I.e., highway driving, cornering, and low speed driving. 2010 audi s4 produced in 2009 clearly have a defective water pump, which tend to mostly fail prior to 10k miles on the car. Many s4 owners and forum members reported many kinds of hazard that this failure can bring, including coolant spilling that can potentially harm the surrounding motorists (slippery surface caused by oily coolant) and the loss of power steering which can be extremely dangerous on highway. My water pump has not failed yet, but from the failure ratio shown on a audi s4 owner forum, it can be clearly seen that most of these water pumps will eventually fail at any mileage. I am seriously worried about endangering others, myself, or my family members because of this potential failure on the water pump of 2009-produced 2010 s4. I would appreciate your concern over this issue.
I am writing to complain about a design flaw that has been identified in the waterpump used in the 2010 audi s4 3.0t. Several owners have experienced a waterpump failure which results in the vehicle overheating and partial or full loss of power steering. Owners who have experienced failure have had their 'black plastic' waterpumps replaced with a revised 'aluminum waterpump'. Several owners have complained about this issue on various enthusiast forums, but the manufacturer has failed to acknowledge the problem and issue a recall. It is evident that the waterpump is a ticking time bomb that needs to be replaced so individuals are not 1) left stranded on the side of the road, 2) subject to an automobile accident due to lack of power steering, or 3) at risk due to an overheating vehicle. I personally have not experienced the failure on my vehicle, but I am submitting this complaint in hopes that the federal safety agency will work with audi to issue a prompt recall for all affected owners. I do have the old revision of the waterpump ('black plastic') on my vehicle and I am worried that I may eventually experience a failure. The following are some posts on various enthusiast boards that highlight the issue: http://www.audizine.com/forum/showthread.php/382525-another-waterpump-bites-it...?highlight=waterpump http://www.audizine.com/forum/showthread.php/317505-b8-s4-water-pump-failure?highlight=waterpump http://www.audizine.com/forum/showthread.php/352343-problems-so-far...-today-the-water-pump-blew?highlight=waterpump http://www.audizine.com/forum/showthread.php/349318-my-coolant-broke!!?highlight=waterpump http://forums.audiworld.com/showthread.php?t=2789310&highlight=waterpump http://forums.audiworld.com/showthread.php?t=2789742&highlight=waterpump http://forums.audiworld.com/showthread.php?t=2774524&highlight=waterpump http://forums.audiworld.com/showthread.php?t=2773666&highlight=waterpump.
