I think you may have inadvertently flipped the pre & post facelift types of alternators around...so just for the sake of clarification for those that may not know...the breakdown of alternators vs e53 engines are:
- M62TU B44 - water cooled alternator
- M62TU B46 - water cooled alternator
- M54 B30 - air cooled alternator
- M57 D30 - air cooled alternator
- M57N D30 - air cooled alternator
- N62 B44 - air cooled alternator
- N62 B48 - air cooled alternator
BTW assuming that the 4.4 in your handle is indication that you have the 4.4 liter engine in your car...by not having a signature or vehicle info that indicates what model/model year/build date you have...it's not clear if you have the M62TU 4.4 or the N62 4.4 (totally different engines as you know). Identifying which model/model year/build date you have helps those that find your posts (doing a search) or when you reply...have a perspective of what you say or have done etc. If you mod or update your X...they can immediately know if it can apply to their model or not based on where yours & theirs falls within the production date range.
