I had a blown motor on my 2010 at about 23000 miles. I purchased that M3 used as a lease assumption from an owner here. bmw replaced the motor, but i did not want to deal with that car, nor was I comfortable with it after that. I traded it in for a 2012 comp package. i did get the ticking sound after the 1200 mile service (probably still there), but now my exhaust is too loud to hear it
