Cured my cruise problem by just putting in the correct tail light bulbs. Your tail light bulbs can only be Oschram or Bosch. Do not use #1157 generic brands you pick up at your parts store.

Using #1157 bulbs, will never give your cruise control that critical ground signal it needs to function properly. They just are not designed for the Mercedes.
