Are N54/55 Alternators compatible with the N52?

Volasko · 10-10-2018, 08:07 AM

A bit of a long shot but I have my IM off to swap a starter that failed and I figure it would be a good time to swap the alternator too on my high mileage N52 (260k km or 162k miles). I found someone parting 2010 335xi which I'm already taking the starter from. Aside from ensuring the amp rating matches is there anything else I should be aware of? A part of me is hesitant tossing in a newer unit with regards to it being compatible with the older 2006 control modules. Anyone do this with success? I don't have coding capabilities. Yes I checked the part numbers on realOEM and they don't seem to match.

Quick responses are appreciated, I'm meeting the guy soon to pick up the starter.

I don't think so, the whole pulley arrangement and mounting of the accessories on the N54 is different, as the AC is on the drivers side to make room for the turbo.

Make sense, not really worth risking it.
