Water pump OEM Audi or Pierburg

This time the shop foreman went through the car soup to nuts again, replaced a fuel rail connector, and the water pump.

2015 B9 A4 3.0TDI. Almost at 200k. Original waterpump and no issue in sight.

Audi made it right by making the oem water pump replacement aluminum, not plastic smh.

I bought a 2017 S3 with 40k kms, best car I’ve owned so far, had to replace the water pump but I swear the OEM one is made of cardboard. No more expensive than any other car to service.

To answer the second question, bro, this happens to every Audi owner. Like it’s extremely common for water pumps to fail, mine is In the shop to get a new water pump, and my guys noticed there was 2 small oil leaks.

Pierburg water pumps are known to be good for about 60-80k, which is the usual time they fail (they either leak or the electronics inside fail).

My Audi s5 back then had the v8, and around 43-45000 mi I had to swap mine out

I got all aluminum Pierburg water pump to replace (working) VDO water pump. After putting everything back together, bleeding the system, I turned on the car, drove 40 miles with a couple on and off cycles and then shut it off for a couple of hours. I came back, started the car, I got the low coolant level warning, understandable, air escaped the system (I guess I didn't bleed it enough lol). Topped it off, drove 20 miles back home and then heating suddenly stopped working and coolant temp started rising. Went from 95 C to 100, then 105 and that's when I shut the car off, didn't want it to overheat. Ever since then, my pump works intermittently. I had a laptop set up next to me with INPA on today and drove close to the house to have the car ready for emissions (thank God!). After bleeding the system two more times yesterday it seemed like it was fine but while driving today, after maybe 20 minutes of driving, the pump stopped working and would not come back on again. It was like trying, the percentage rose to 30-35% and then back to zero immediately. Temperature went from 90 C to around 110 C rather quick obviously. Then out of nowhere, it started working again for a bit. Got close to the store I was going to, and it stopped working again. I was able to pull into the parking lot as it got to 120 C and got a yellow overheating warning. On my way back home from the store, the pump only started working again maybe 3 minutes from home, had to stop once and then turn off the car and keep rolling most of the way to not let it overheat. Also, there's no heating from the vents until I set it to 28 C but at the same time there's no movement from the pump in INPA.

I find it weird that the water pump went bad since i changed it about a year ago with a Pierburg water pump. Next morning my car started overheating. Tried bleeding the system and the pump wouldn’t engage.

I have the same exact issue on my 2021 Q8 coolant leaking in vaccum system they want over $8k for repairs just hit 51k miles
