Porsche's break-in is 600 miles btw. Side note for dct owners, he said a new bulletin is out that does now NOT require clutch fluid change at 1200 miles. Found that interesting.
Its in the service manual for the 2011 M3. Don't change the transmission fluid for DCT do it for manual. Despite that I could not get the first place to change the tranny fluid and had to go to a different dealership to get it done. I am at 2500 miles, so far no problems. Used common sense during break in but did violate the speed part. Had it up to 125 on the autobahn. But tried hard to get the RPM's below 5500.
