Water pump OEM Audi or GRAF

I personally replaced the water pump on my Tiguan with a Graf aluminum pump. The only issue I've had was the rubber o-ring on the temp sensor leaking. I replaced all the rubber seals with Rein branded ones and no more leaks.

I have a 2016 A6 2.0T w/52K on the clock now and it's been reliable thus far, although I did have to replace a water pump at 17K.

Had my water pump replaced around 50,000 miles in my 2017 A4 2.0t. Other than that, the car has been rock solid.

I finished the water pump replacement with the Graf Aluminium pump. Nice pump. As per Qmulus recommendation, I replaced the coolant sensor Oring with OEM. While in the process, I replaced the oil filter housing along with a new oring for it.

I have been running the Graf AL pump for about 10k so not long enough to give a full assessment, but the quality was awesome and very pleased with it.

Now, I had to get the motor mounts and water pump replaced. Pump was leaking a bit, not taking chances with that.

I was topping up the coolant every month or so. Was advised I would need a new water pump, which I was expecting

Had to get water pump done on my A6 at 90000km / ~56000 miles. Was a couple years older than yours at the time, but still felt pretty low mileage to me.

Just be aware that B9’s are subject to water pump failures which can lead to the engine overheating. For months (Since March) I’ve noticed a “Whistling noise” coming from the engine bay while driving. Took it in to get it looked at (non Audi dealer) and was told it was normal. Drove it and drove until one day the car told me I had no coolant… that’s odd. Go buy coolant and keep driving. Now the car overheats and spits out all the coolant. Now it’s making sense. Either a combination of bad TStat sensor & water pump or just bad water pump. The fact that it never told me the coolant was hot the first time is spit out all the coolant leads me to believe both components are bad.

Had mine replaced last month before it broke again. The component that failed was the gasket for me then the pump failed and wanted money.
