I think the 08 M3 engines dont seem to be as well made as the 2009 ones. The 2008 ones have Main Bearing issues as well which SnowsM3 and Knifegun's car had. Of course not all, but its still a cause of concern.
You've really got to stop confusing the two. Per your post elsewhere, they initially voided your warranty due to ECU mods. I'm not agreeing that this caused your problem, but mischaracterizing their reasons here is just not right.
