My alternator just crapped out on my M3 (due to a pretty massive stereo system).

I believe the OEM was a Valeo. However after doing some research, it seems that the Bosch alt, more powerful than the Valeo, will fit/work. It is also less expensive.

Can anyone confirm?

Thanks

 

No can't confirm. No GT2, No care.

 

Quiet you!

Valeos OEM and should be 120A. As far as I know the Bosch should be 120A as well. Maybe youre right and its a 140A but I can't recall.

In my experience the reman'd Valeo from BMW is a better quality alt. The Bosch starters and alternators do not seem to be holding up like they used to. Bosch is def cheaper, probably almost half then one from a dealer. 2 year warranty from BMW, I think 1 year from Bosch.

For half the price Bosch is probably the way to go. 500+ bucks for OEM/bare bones very basic alt. is robbery.

 

Thanks^ Yes, the Bosch is 140. To bad no one makes an upgrade for those of us who have 150 lbs of stereo equipment.

 

You can probably find a local alternator shop who can acquire parts for an upgrade.

 

I got a remannied Valeo from Pep Boys. I had to drive 45 miles to get it, marked down to $129. It also has a lifetime guarantee which will com in handy since my car has a serious sound system.

Score!
