my hepu has been in for 9 years with zero issues
Pierburg ONLY for water pump, no other brand is good.
with water pumps on e9x’s it’s Pierburg or bust.
Hepu pumps are the best.
Water pump if stock would have a plastic impeller known to fail, but you can find metal impeller options from Graf and Hepu brands and from other aftermarket brands too.
I replaced my water pump last weekend with a new pierburg pump from ecs tuning, everything went smoothly, no leaks, etc.
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).
Honestly, personally I wouldn't get a Pierburg. Got one, the all aluminum one and it failed right away, first day of driving. It was hard to push in the plug as well. And they are made in China these days, cheaply made it seems.
a Hepu which went seven years/60,000 miles before it started leaking. I think the additional mass of the metal impeller put more stress on the bearing and seal.
Am pățit la fel dar cu o pompa Hepu, a mea a avut un sunet înainte să crape și la 120km/h a cedat axul, similar cum a fost a ta.
