As far as help from Mercedes Benz or the area rep, good luck! I had issues with my 350 and the area rep did absolutely nothing to help get the issue resolved.

The dealer however, went out of their way to help. The issue was not corrected but I will give them credit for trying.

I had my 55 in for the first service last week and the dealer had a 2008 55 with the 030 package and it had the 6 and 4 piston set up.
