Mishimoto Electric Water Pump – BMW N54 / N55

OVERVIEW

The electric water pump on the N54 and N55 is a well-known failure item, and when it goes it usually goes without warning: a coolant warning, then limp mode. Mishimoto's MMWP-N54-07 is a direct OE replacement for that pump.

Fit it as preventive maintenance on a high-mileage car or as a repair when the original fails. It is a reliability part, not a power part.
