Water pump OEM Toyota or OEM BMW

I’m on year 3 of a 2020 M240ix and it has cost me nothing besides regular maintenance and premium fuel. Now I expect that to change soonish, as at my last oil change I was told my water pump has a very slow leak and, at some point, will need to be replaced to the tune of $2k.

My 99 V6 just rolled 316k, am looking into my 2nd timing belt/water pump DIY

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

Engine water pump is leaking coolant. The pulley and drive belt are slinging the coolant onto other components. Highly recommend to replace with factory parts.

Electric water pump is leaking, replace with an oem toyota part dont cheap out and go aftermarket on this part.

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

I've owned my 2013 535i M Sport since 2018 with 44k miles. Other than the regular maintenance items... 2021- oil filter canister gasket replacement -$ 800 ( I think. I can't find the receipt) 2024- passenger valve cover gasket- $660 Driver's door handle replacement -$250 2025- water pump and thermostat- $1750

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 my issues with the 2nd gen (water pump failure)

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.
