Is there any significance to the coloured dots on the wipers of my C250 W204 estate?

In theory you should replace the wipers once the yellow dot is fully visible.

I say 'in theory' because my experience was that the wiper blades were perfectly serviceable for a number of months after the yellow dots were showing.
 
The idea is that the yellow dots get exposed as result of UV sunlight, and it is assumed that the same UV sunlight would have caused the rubber to deteriorate. But my recommendation would be to ignore the yellow dots and replace the wiper blades based on condition. I.e., if they are not smearing and working fine, they can stay...
 
Ok thanks for the replies. The wiper with a black dot doesn't wipe well and the yellow dot is marginally better.
Both need replacing in my opinion.
 
What year is your car?
 
I believe this is the original MB wiper for your car:

Clean the screen using a paper towel and glass polish (or the Rain X glass cleaner spray - excellent product). Also clean the wiper blades by wiping the paper towel ( with cleaning product) down the length of the rubber.
