Does anyone notice clicks (or light pops) during tight turns and slow speeds? Like entering and exiting a parking spot. This happens in forward or reverse. Any ideas? Is it just the 4 matic?

Also, why does the eco auto shut off automatically re-start the engine when you release the seat belt? (Just curious)

Clicking on tight turns, as you are describing are sometimes related to CV joint wear. The 4Matic has lots of moving parts, so you might want to try the same turns using a car in the dealer's lot to see if this noise is customary.
