Cracked waterpump

[Nick9one1]

I've been slowly loosing coolant and have tracked it down to a cracked waterpump (my second in 4 years).
This seems to be a common issue on the N54.

Spotted this upgraded replacement made by Pierberg with a fully metal housing for a good price

That shows as being incompatible with the z4? :?

That’s the same one I got from Autodoc that failed after 900 miles, I was probably unlucky as others have had no problems with it, and it’s about £20 less than I paid.

not sure where your looking?
35i water pump part number is 11519455978 - this is on the part
and it also lists the z4 35i at the bottom of the page

I filled in the vehicle details using the table, it shows as not fitting the 35i?

I wouldn't trust the ebay compatibility checker. It definitely fits the 35i

Hi, yes I had that one fitted after my OE item barfed at 60k…5k miles so far but OK…I think Chippie was unlucky..hopefully..this pump is well regarded on various N54 forums..
