confused about water pump part numbers
For my 2007 328i (N52, base model) I'm trying to find out if the electric water pump with part number 11517586924 is the same as 11517586925? I was given what I thought was the 925 but turned out be the 924 part.... I see the primary number in all the internet parts lists as 925. Is this an earlier version? I read about an impeller upgrade somewhere along the line. Any help would be much appreciated.
