Water pump Hepu or Pierburg

It has a hepu water pump

I went from that just up to the Pierburg ones and it was a night and day difference.

have a pierburg water pump, it’s holding up pretty well.

GMB or Hepu pumps are generally good for 100k or more.\n\nThat leak is due to the donut like seal between the pump and the head.

The Pierburg pump is an all aluminum upgrade. I put one in a couple months ago. It works great, less prone to leaking and I have only ever read/heard good things about it. It is even a few dollars cheaper than the OE VDO pump.

When I was shopping around for cooling system replacement parts, I wasn't sure if GRAF or HEPU made a better metal-impellar water pump. I ended up purchasing both the GRAF and HEPU, and found the HEPU to have a better fit and finish compared to the GRAF.

Pierburg. It’s literally exactly the same just no BMW logo.

Every one I've ever gotten from GAP has been HEPU. The one in my GLI was really noisy for almost a year after installation. The other two in my GTIs never gave me any problems.

Replacement HEPU water pump is now leaking… from the freeze plug.. gonna let it ride and try a different brand when I change the belt in 50K miles

I’ve now popped two water pumps. Each of them have sprung a leak from the freeze plug. I seat the pump and o-ring by hand then torque bolts to spec.. each time they’ve been good for about a month or so, then start leaking from the freeze plug.. both pumps have been made by HEPU.
