540i Auto '95 Euro Starter Motor Type(s) ?

[bagpuss]

I'm in need of a starter motor for my 540i and thought I'd get a 2nd hand one, however, the suppliers I've spoken to tell me there are 3 different ones for this car which suprises me as 'RealOEM' lists only one type, but either a new one (that's been discontinued) or a remanufactured one. The part #s listed are:

STARTER 1,7 KW 12411729982
RMFD- STARTER MOTOR 1,7 KW 12411736922

(Which I am assuming is the same single type, just the different PNs to differentiate the 'new' from the 'remanufactured').

So is there any truth to what the supplier is saying about different types ? Which would indicate that 'RealOEM' has the wrong info ?

Cheers.
