Hi, Felder, and welcome to the forum.
First, whenever you have something specific to your model it's always best to post in your native forum instead of one of the general ones. Scroll down and you'll see them all, then just pick the correct one. And if you have something really specific -- like an error code -- you can use the search function and usually find posts relating directly to it.
In this case your specific forum could confirm/deny the following, but the fuel trim codes in late-model MBZ's are most often the mass airflow sensor (MAF). If you're handy and a DIY type, it's a simple enough item to replace and if you wish to pull it and disassemble it, you can also clean it, which sometimes works.
Take care and enjoy the ride,
