I just purchased a four-year extended warranty from my nearby MB dealership on my W211. My 2008 W211 just turned over 41K miles and I recently notice while driving to slow down, my car has a slight "abrupt-jerk-feeling". I have read from several post that I may need a software update (assuming this is the case). I also notice a faint knocking sound from the rear of the trunk - I don't know if anyone has had this odd sound experience. Otherwise, I have been pleased with the car to-date and I want to get feedback of what maintenance work I should get done during my extended warranty period?

Thanks.

What did you pay and who is the issuer of the Ext. Warranty?
