What is your question?
Top, locks, trunk won’t operate. Dealer diagnosed said 90% probable PSE, but front SAM need to be replaced first. However, after dealer diagnosed, EVERYTHING worked fine for a day.
How long has your 2007 Mercedes-Benz SL550 had this problem?
Several months

Hello, and then it stopped working again? Your dealership -- or other local qualified repair facility -- is in the best place to assist you. I'd say you'd need to replace components in step by step process due to the testing that's being done. But, it's only based off of theory - hands on testing is needed.
