Oily rag

Hi all,
I have a 2010 W204 C180 and recently had the camshaft position sensor replaced.
The garage replaced a Bosch 0232103050 also marked A0041539628, with some unmarked item.
I would like, in time to replace it with the correct sensor but cannot seem to find the correct part number.
The 050 look like it was the original part but all sites seem to say Bosch 0232103114 is the correct item. HELP!
