I'm pretty sure you could reach through the front grill right next to them... That's how I do it on my pre-face lift CL9. I thought you could do it the same way on the new ones. And all it would be is a screw holding it on place, undo that and it should pop out and then twist and replace. If you can't do that, then you can generally do it without jacking the car up, just fit your hand underneath and i'm sure you'll be right.. haha. That's all I can think of!
