Water pump OEM Toyota or OEM BMW

My water pump lasted 420,000km

My water pump went out at 155k, 2006 BMW 325i auto

I’m at 180k, holding strong

My 330i started throwing codes around 135k. Replaced it for peace of mind and it turned out to be the original. I’ve heard somewhere that the water pump used in the 2006 325 and 330i is a bit different and lasts longer

Original water pump, lasted to 167k!

Had a friend rebuild his 22RE, guy ordered his parts from eBay. Parts to replace which I believe is a must, water pump, t-stat, oil pump, timing chain and tensioner.

I replaced my water pump at about 205K miles. I had seen someone on e90post mentioning he saw fault codes before his pump failed. I decided I could wait if I kept a close eye. At about 205K miles was when I saw a fault code via ISTA/D. It mentioned something about "...water pump speed deviation..."

That looks like the water pump but I can be wrong. Also, there is no dipstick for the transmission anymore. Depending on the engine, there is a drain bolt on the side of the transmission on the driver side I believe near the drivetrain.

How many miles do you have? Its probably time to change the water pump if it's making noise and if it is, it needs to be replaced before it causes a whole world of hurt to your wallet.

Yup that's how my Z3 once tried to kill me. Doing 90kph on the off ramp and the ol water pump decided to retire. In the process dousing my rear wheels in coolant.

OEM. Went aftermarket 2 times in a year replacing that pump. Finally bit the bullet and paid for toyota part.
