During a Saturday trip in my ML55 the command system suddenly shut off and a loud knock began comming from under the dash. The knocking continued loudly even with the car shut off. I pushed the "i" and "Service" buttons but the tech had no idea what it was. I took the ML55 to HBL Mercedes in Tysons Corner, VA and tech wanted to pull the entire command system out. I suggested simply removing the 25 AMP fuse. Once the fuse was removed the pounding stopped. When I got the car home I put the fuse back in and everything seemed back to normal. However, the navigation system was giving backwards directions. I pulled the disk out and re-inserted. Now everything seems fine. Have any other ML owners experienced anything so wacky?
