Cheap BMW 3 Series Water Pump

The E90 generation ran from 2005 to 2012, with a facelift in 2008, so both years sit within the same generation — but fitment depends primarily on the engine code, not the production year. An N46 will need an N46 pump, an N52 an N52 pump, and a 2.0d M47 or N47 will need its own diesel-specific unit; swapping across engine families won't work even within the same generation. Give the breaker your engine code (found on your V5 or a VIN check) and they can confirm whether a specific unit crosses between those model years.

These are different generations — the E46 ran from 1998 to 2006 and the E90 from 2005 to 2012 — and while some engine families (such as the M47 diesel) bridged both, the pumps are not directly interchangeable because ancillary and mounting configurations changed between platforms. Even where the engine code looks similar, you should confirm physical compatibility with the breaker against your exact registration before buying. The engine code is the most useful detail to have ready.

No — SE, Sport, M Sport, and other trim levels are cosmetic and equipment packages; the water pump is determined entirely by the engine code, not the badge on the boot. An E90 320i SE and an E90 320i M Sport with the same N46 or N52 engine code use exactly the same pump. When sourcing from a breaker, ignore the trim and focus on supplying your engine code and registration.

Both the 320d and 330d are diesel variants and in the E90 generation used variants of the M57 or N57 engine family, but the specific engine codes differ and so can the water pump specification. Do not assume a 320d pump crosses to a 330d without checking; supply both engine codes to the breaker and ask them to confirm against your registration. Getting the engine code from your V5 is the safest starting point.

All BMW 3 Series variants — petrol and diesel — use a water pump as part of the engine cooling system, so the part genuinely exists across the range. Some later engines (notably certain N52 and N53 petrol units) use an electrically driven auxiliary water pump alongside or instead of a belt-driven mechanical pump, which means you need to be clear with the breaker about which type you need. Confirming your engine code and whether your current pump is mechanical or electric will save you from ordering the wrong unit.

The E92 coupe ran from 2006 to 2013, with a facelift in 2010, and whether a pump crosses that boundary depends on whether the engine code and specification remained unchanged through the facelift on your particular engine. The body style — coupe versus saloon or touring — has no effect on water pump fitment whatsoever, as the pump follows the engine. Confirm with the breaker against your registration whether a specific unit from before or after 2010 will suit your exact engine code.
