What sticks out to me are the part numbers. Since your car is a W203 series, shouldn't the first 3 digits of the part number correspond? W210 is an E-Class and W221 is an S-Class.
The dealer replaced my sensor and it didn't solve the problem. As it turned out, after some exhaustive diagnosis, that my aftermarker windshield is the problem. I still have the old sensor and if it will help you, I will find it and give you that part number.
<edit> My old sensor is A 210 820 57 10 and the female end looks just like your first 2 photos with 3 prongs.
