Water pump OEM BMW or GRAF

I have 27K miles on a Graf with no complaints.

I installed the aluminum pump (Graf) on the wife's Tiguan and it has worked great since. Have put 40K miles on the metal pump and no issues.

GRAF makes this particular pump without the magnetic impeller, and it’s the best option.

I would STRONGLY recommend you to buy ONLY a BMW stamped WP. I learned my lesson the hard way and want to help you avoid my mistakes. The main thing that fails in electric water pumps is the electronics, and the ones not stamped with a BMW logo often have these issues.

Graf is good. They are an OEM (original equipment manufacturer)

I run a Graf pump myself for about 2 months now and it's working fine so far.

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

I just had to deal with a Graf pump failing at 6000 miles on my CRUA. Everything is low quality trash now.

This has happened to my husband. He drives 2021 m340i with 17k miles. Water pump exploded last night.

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.
