Water pump AISIN or Pierburg

Water pump and timing belt done with OEM Aisin kit (March 2024)

Just replaced my water pump and thermostat on my 2015. Aisin pump, which is oem was $150 on amazon. $40 for the thermostat. Super easy to replace yourself. Especially if they want $4000 to do it.

Pierburg ONLY for water pump, no other brand is good.

with water pumps on e9x’s it’s Pierburg or bust.

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

we always used Pierburg assemblies with Mahle gaskets/o-rings if needed.

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

I ordered this water pump from aisin hoping to receive an oem quality part but it seems the molding is not of quality.

when my original pump went bad, i went to Peirburg so that the plastic housing wouldnt crack. Pump lasted about 20,000 miles, bought another one from fcp euro for the lifetime warranty but this one lasted 20 mins before i got those same codes and overheated.

I've had 2 of these die in less than 1 year. Junk!
