New Alternator
 
My alternator went out last Monday. At first I was not sure, the battery icon was on and off intermittently, never steady. I was debating if I could last till the weekend but then i figured.. better not. Pulled the car in the drive way called work to tell them I was going to be late and called O' Reilly... $ 209.00 rebuilt :rolleyes:...
I did not have to remove anything other than the air filter box and move the steering pump reservoir. The job took a whole 2:00 including the trip to the store to test the old alternator and grab the new one.
I was at work at 9:45 AM
Car been running ok since.

I know I should have done the bearing, regulator and brush myself but did not prepare for it and I got life time warranty so in the case it fails again well I can say I got a bit of practice..

Liquid cooled
 
Isn't the Alternator on a E39 540i liquid cooled? Did you need to drain the coolant?

Yes, but the OP has the 2.5 I6. Edlack has the V8.

Drain?? Pffft.

I didnt drain. Just disconnected the small hose going into the alt jacket. Caught mostly everything underneath. Just let the engine cool of substantially before going this route.

Ask me how I know? Smh.
