Good pix and they reveal an oil spill on the engine cover that probably got on the hose. Very sloppy work. I'd have the dealer clean it up, if you trust them at all. There are accounts in this forum of such spills getting on the alternator and causing it to fail. No excuse for the dealer to not follow factory procedure, that's what you are being charged for. I'd put this all on paper and give them a copy so it is on record.
Make sure they are in fact using the Mercedes spec oil listed in the owner's manual.
When you check the oil from time to time do it at one engine temp. It varies as much as 1/2 qt in my experience. When it is cold do not fill it beyond half way between min and max or it will be overfull when hot. Ask me how I know! No harm was actually done but you never know.
The usual warning: Make sure the seal between the turbo and the air inlet hose is black, not orange. The orange ones leak blow by oil and that leads to swirl motor failure, as alluded to in the last post.
