Water pump OEM BMW or Saleri

A 525tds was my first car. Only ever had two problems with it. Heater fuse kept blowing- turned out the previous owners install of the head unit used eletrical tape which over time lead to a cable shorting out on the din cage. Water pump died - oem impeller was plastic. The replacement was metal

I replaced a perfectly functioning OE Saleri at 12 years/90,000 miles. I will stick with the OE Saleri even though it has the plastic impeller.

i replace with OE saleri pumps every so often and havent opted for a stewart pump.

153k miles on my original WP. Still going strong too.

Has 137,000 miles on it original water pump. Still good to be used but don’t know when she’ll crap out. Very impressed that I lasted this long.

Saleri is what I put in. No issues about a year in.

Buy the M340i new and prepay your services. Great on gas but insurances and tires have been expensive. Water pump blew at 48k.

I had a Saleri pump. I changed it at 100,000 in 2013 and bearing was good at around 145,000 in 2021. I inspected it with a camera. It appeared to be leaking at the gasket.

The Saleri started leaking at the shaft so it wasn't an issue with the gasket. The Saleri had a plastic impeller while the OE had a metal impeller.

The water pump had a micro leak that would spray coolant on the air box. Never enough to make me want to go through the trouble of replacing it.
