Bought my 08 E90 M3 in Oct 09 with 5K miles. Just swimming through endless amounts of information.. I called the dealer about this SI B 00 04 08 bulletin related to transmission and differential fluid change and a couple other things. He took a look at it while I was on the phone and said that specific service bulletin mentioned 2009 models specifically but he would check with his master tech about relevance to 2008 models and call me back.
Any chance anyone has a copy of that bulletin?
