Water pump AISIN or OEM Audi

Rotors/ pads\nKYB shocks\nOEM Aisin water pump\nRear brake pads\nFront calipers

My impression was (recommended by many) this specific seller had everything OEM, water pump was the correct Aisin one.

RockAuto Aisin with the logos ground off. That’s when you know it’s the real deal.

Aisin only. It's the Oem.

Aisin TKF-005 has the 2 port pump and is otherwise identical to TKF-004 with the 3 port pump.

Water pump went out on two of mine around 100k.

Aisin Timing and Waterpump Installed... not buying again as the plastic turbine broke and caused the headgasket to blow.

2019 Audi Q8 water pump failed around 80k miles. After looking into it, I found out Audi originally used a 4-bolt water pump and pulley design on these engines. The problem with the 4-bolt setup is that it didn’t distribute load evenly. Over time this caused premature wear on the shaft and bearings, which led to leaks and pump failures much earlier than expected. Audi must have known it was an issue because they stopped producing the 4-bolt pump and redesigned it with a 6-bolt system that spreads the load better and holds up longer. This wasn’t just normal wear—it was a weak design from the start.

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

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
