Water pump Pierburg or OEM Volkswagen

Mines at 85k, no probs yet.

I'm currently sitting at 67k miles on my 2019 GLI without any issues. I'm pretty sure I won't have an issue by 80k miles.

My original water pump lasted 115,000 miles. I saw the fluid levels subside over the years, but never actual signs of a leak. Eventually, the leak became obvious enough to diagnose.

Just wanted to follow up. Took it the dealer. Later that day, they diagnosed the water pump failure, got my green light for repair under CPO warranty (with $50 deductible), and by the end of the same day the car was treated to a new thermostat/water pump. They recycled the coolant they drained and topped it off - a flush would have been extra. Service advisor said they pressure tested everything when I asked about the cap and everything passed. Let's hope this holds up!

Generally the OEM plastic water pump only lasts as long as the timing belt interval. I wouldn't rule it out since the overflow water you might be seeing could just be water which is expanding or boiling as you increase the engine speed.

I too chose pierburg from fcp. Questionable weather it\u2019s any better than oem. I appreciated the all aluminum housing of the pierburg as it provides one less failure point which is the possibility of the plastic cracking due to an over torqued hose clamp.

The tech noticed the water pump was leaking slightly. All got repaired under VW warranty which was lucky as it was around £1800 otherwise I think. Anyway, the weird thing is the car always lost coolant from new - it would drop to the min level, but they couldn't find a fault when I mentioned it until they physically found the water pump leaking after 4 years and 40k miles. I think the pump is plastic which may not be ideal.

I picked the pierburg for all aluminum casing and impeller. They were both about the same price last time I needed to get one. Note that the pierburg failed at not even 10k miles. I replaced with another pierburg chalking it up to bad luck. The only advantage I can think of with the pierburg is the fact that you can torque down the hoses that use clamps and not have to worry about cracking the housing. But in reality doubtful that is a risk. Also it won’t be in service long enough to get brittle enough to matter.

VW TSI water pump: garbage.

That is indeed a common failure item on the 2 liter turbo engine. One of my VWs went out @ 70k miles.
