Water pump OEM Audi or GMB

I replaced both mine and my dad's with GMB. Mechanic recommend it too. So far so good.

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 have a 2018 A7 and I had to replace the water pump (which apparently is pretty standard). The dealership charged me $1450 in an affluent Philly suburb for what that\u2019s worth.

I owned a 2009 4.2L V8 S5, had to get a new water pump & housing. euro specialty shop did it for me for ~$700.

My s5 water pump failed at 300 miles, car wound up lemon’d.

Since Audi clearly makes water pumps on presumably a $50 3d printer, would it make any sense at all to buy an upgraded one, metal or whatever won’t do whatever oem ones love to, and preemptively change out ?

I had mine done on my 2018 S4 from an Audi dealer in PA. Cost me $3,928 total. They replaced the water pump and hoses, coolant regulating valve, vacuum control valves and lines, and the serpentine valve. The water pump is what failed and took everything else with it.

Audi doesn't have the best record with water pumps and housings. On the 8V S3, the pump would start to leak, but it would drip onto the splash guard and never make it to the ground. The only signs were coolant smell and frequently needing to top off the coolant.

2017 Q7 3.0T. Steadily using more oil over life of car. Now a quart every 350 miles. It doesnt have the power it used too. $1500 for a new water pump at 54,000 miles.
