Water Pump, Continental - 135i/335i/535i, X3/X4/X5/X6/Z4 35i (N54, N55)

The water pump used in the 2007-2015 N54 and N55 turbo 6-cylinder cars is electric and plays a vital role in managing temperatures for multiple systems throughout the car. However, because it's electric, when it fails it does so completely and without warning. We strongly recommend replacing the water pump before 80,000 miles.

BMW changed to an electric pump to reduce emissions and make the engine more efficient. Pumps driven from the engine accessories used up fuel which made for more emissions. Electric pumps only work when they are needed and only require the alternator to supply power. Because the engine computer regulates engine temperatures, the water pump only needs to work when it has to (including after the car has been turned off). In theory this should make the pump last longer. But it's the electronics inside that fail and will force a replacement, often without warning. Although if you are religious about oil changes and checking/clearing fault codes you may get a soft (hidden) code for low water pump output ahead of time.

This is the OEM Continental-VDO-Teves water pump. Continental is the original supplier to BMW for this water pump as well as many other components on the car. We feel that the OEM pump is the best option for this because of its higher build quality and two year warranty (most aftermarket brands only offer a one year, including other German-made brands). 

This is the latest version of the N54/N55 waterpump, featuring an updated design which replaces the old BMW part number 11517563659 (11-51-7-563-659)

The three (3) mounting bolts for the pump are required. In an effort to reduce weight BMW uses a very light weight bolt that can only be used once. You can order the bolts separately from the link below or clicking here - BimmerWorld part number 11 51 7 602 123 (click to view). We also offer this pump with an OEM thermostat and mounting bolts (see below).
