Water pump OEM Audi or Hepu

the aux water pump is leaking you can do it without taking the intake manifold off thru the driver side rear if the engine shouldnt cost you more than 200 when your all done

Metal impeller model is available but can be hard to find (Hepu brand). Recommended interval for changing is 80-100K depending on who you talk to. But many fail earlier and may fail as early as 20k. Change as preventive maintenance.

The waterpump in my kit from germanautoparts.com was made by Hepu.

I have the Hepu unit in my car. It's been going great for the past 45k miles. Both are good options. I would go with what is cheapest.

i bought the dieselgeek timing belt kit which includes the Behr german Thermostat and Hepu water pump. he says that the stock OE style thermostat is better and the reman OE pump (which now uses metal impellors) is better than the hepu.

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.

Had the dealer do the water pump on my 09 A6 3.0t and it was like $1800 for that alone.

Waterpump and thermostat are common issue with Audi. I had a 2017 S3 and had it replaced around 65K miles, and now my 2019 S5 was replaced under warranty at approx 38/39k miles. The mechanic mentioned something along the lines, its made out of plastic.

My water pump and thermostat just went out on my ‘18 Allroad and was pleasantly surprised to find out that they were both under an extended warranty even though my car’s general warranty had expired last year.
