Mercedes C63S front bumper trim

[simon737]

Hi,

 Noticed whilst washing, that the top part of the ‘aero’ trim on my front bumper has changed colour ever so slightly from gloss black to an almost purple colour, so much so that you can see (what I think are) the mouldings from the factory? (The rings) Is this a warranty issue - the car is just over 1 year old. 
 

Cheers. (Had posted in Merc forum but think it’s been a while since anyone visited)
