How much did you put in? If you likely overfilled by just a little bit, then it may not be that big a deal. But if it's any significant overfill, then you definitely need to drain some out because overfills are not good. The best way to cure overfill on this car, from what I've heard on this forum, is to drain the front sump. There are two sumps on this car and therefore 2 drain plugs. Let the front one drain and that should be about a quart. If you need to top off slightly afterward then you can but I imagine that won't be necessary (level will probably be somewhere in the "OK" range after enough driving to get a proper reading).

I remember seeing on this forum somewhere that sucking out from top is not possible on the M3. Don't recall exactly why...
