Water pump Gates or OEM Audi

I used a gates water pump on mine and have had no issues

Update: it was the water pump. Got a new Gates water pump (screws and gasket included). Installed it, no sealant or anything. Works flawlessly. Not a drop anywhere.

I used the gates kit from rock auto including the gates water pump… Car seems to be driving fine for the past few thousand miles since install.

I went with a gates.

I remember on my S4 the water pump had a plastic impeller that was guaranteed to fail at some point. The aftermarket made one that was metal.

My water pump in my 2020 S4 failed around 45K miles.

'21 RS6 with 37k miles. Got the same error late last month. Been in the shop for 3+ weeks for water pump & vacuum line replacement.

About a month ago, I kept getting the “Engine Coolant Too Hot — Pull over and let engine idle” error. It would literally come on for a split second then disappear. On one occasion, I noticed that the coolant was low so I topped it off. The error went away for about a week, then came back. This time, though, it remained on and the thermostat actually crept up. I dropped that thing off at the dealer so fast… four days later they tell me that the water pump has started to fail and that one of the solenoids had started leaking coolant.

I got lucky and found out my VIN was part of the class action lawsuit for water pumps, got that replaced for free.

Just turned 51K miles and threw an engine light for the first time. Took it straight to the dealer, low boost fault code due to coolant migration from water pump failure. At 51K miles I’m out of warranty with a $7,500 repair bill.
