Water pump Pierburg or OEM Volkswagen

It was the 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.

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.

However the pierburg shouldn't crack as it's all aluminum. That doesn't mean it'll last any longer. My original one (n54) failed at about 60k. Replaced with factory. Then replaced that one with pierburg as I was doing oil pan gasket and figured might as well since I'm in there at about 90k. The pierburg one failed at 10k miles (electronics jammed up somehow…I’m guessing some sort of freak surge or something as it’s a pretty simple design). Anyway replaced that with pierburg again and going strong albeit it’s only been 30k miles on the new one.

2 water pumps (both under warranty) 3rd one it's on..so far so good. Those repairs cost me nothing.

Water pump has been replaced 5 times. Twice under warranty. Had I been smart I would’ve gone with an aftermarket metal pump.

Mine has also always had constant problems, I’ve spent so much money just replacing the water pump as well. I’ve also considered selling mine, because the cost of maintenance outweighs the fun of the car…

I’m on my 2nd water pump, and it is starting to leak. I still need a third water pump.

Water pump 1 failed during the original warranty. Water pump 2 failed just outside of the new extended warranty for them I think I was at like 101,000 miles. Water pump 3 has now failed. I think im at like 110,000. Im really sick of being stranded in the middle of the night after work and Im sick of paying over $$$ for this obvious problem that everyone knows is a problem with these cars. I cant replace water pumps on average every 3 years. This isnt normal. Im 40 years old and have had many, many cars and 2 work trucks. I have never has a water pump fail on any car ever other than this one.
