I have a 12 C250 Sport and want to replace sport grill with lux, I have the schematic that someone posted with the 4 sections, I have tried many times to remove the grill but have not even got the air intake off, it seems that the releases to take the grill cover off is different on the car than in the drawing.
I of course do to want to damage any of the plastic parts. Can anyone help?

 

You'll find one video clip on youtube...

 

Thank you much
