Water pump OEM BMW or GMB
It ended up being the water pump seal. They replaced the water pump and thermostat free of charge.
Pros: replaced water pump
Vehicle:
BMW
Currently running a fvp, which is just a gmb, and it works great.
Pros: works great
I paid similar for a BMW TBF, however, another garage told me that the garage I went to was known for charging high prices. I always shop around when the price is in the hundreds so I'm confident I wasn't ripped off.
Vehicle:
Volvo S80
I've been running the aluminum GMB pump (1301280AL on Rockauto) on the 455 in my '72 Bonneville for about 5 years now with no problems.
Pros: no problems, 5 years reliable
Part number: 1301280AL
I had my 2008 BMW 135i E88 for going on 14 years, it's about to hit 70k miles and looks like new. I've done a couple bolt-ones (IC, charge pipe, Cobb tune). It's been a great car and a blast to drive. I did replace the water pump this past summer otherwise normal maintenance.
Pros: great car, blast drive
Cons: water pump replacement
Vehicle:
BMW
Mileage: 112654 km
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 $2k.
Pros: love the car
Cons: water pump leak
Vehicle:
BMW
Electric water pump on my BMW was \u00a3436.54 fitted at a BMW specialist (not dealership) OEM pump fitted, the same pump for me to buy and fit myself (no chance) was \u00a3600+ on Euro Car Parts
Cons: expensive, difficult to fit
Vehicle:
BMW
I've owned my 2013 535i M Sport since 2018 with 44k miles. Other than the regular maintenance items... 2021- oil filter canister gasket replacement -$ 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
Pros: enjoyed the car
Cons: expensive when breaks
Vehicle:
BMW
Mileage: 70797 km
I had an 2001 740iL that I traded an old truck for. The electronics are kind of a nightmare, the water pump has a plastic impeller that likes to randomly explode and shoot plastic all through the cooling system. You can buy one with a metal impeller that solves this.
Pros: metal impeller solves issue
Cons: plastic impeller explodes
Vehicle:
BMW
The cooling system is the major weak point (ask me how I know) - water pump failed before 70k (changed under warranty)
Cons: failed before 70k
Vehicle:
BMW
Mileage: 70000 km
