See this rubber edge gasket of CLS63 headlight, kinda "melted" :
Rubbers/polymers aging on its own. The LEFT side is apparently okey, I wonder why.
This gasket is for between the headlight and the hood when closes. Wind and water protection I guess.
I have seen my car interior wiring foam turn to dust as early as car age 7th to 8th year.
My ABS wheel sensors cable rubber clamp guide ( I do not know the real name ) , broke off due to aging.

so yesterday I found a dime sized brake fluid spot under my '13 E350 4matic, brake reservoir was down almost to low mark, so I filled it, then removed all three lower panels, to look, saw nothing leaking. I checked all the lines from the master to the anti-lock and from there to the wheels, nothing, nothing wet under the dash and looking under the hood I can't see any wet spots, but the drip is coming from the front left plastic fender well at the back, this morning it left a quarter sized spot, same place, any thoughts? It's gotta be the master cylinder right? I can't see any leak under the hood either, 
Thanks in advance for your comments,

Just have that problem with unknow leak of one or two drop and low reservior. Then big puddle at few weeks later. Check steel rear brake lines that are notorious for rusting out -- Also the rear subframe. One section replaced at indy with NiCop lines on Right and Left $460. 3 hours labor and $55 material. I would estimate local dealer woud be $1500 to $2000 and using steel line. The NiCop are much better. DOT 4 plus fluid should be used.

The brake line was under warranty until 90K miles? May 2012 had 73k miles.
My old 84 300D brake line was orginal in 2007 and then sold. It was a 10 year MA car that was rusted out in many panels but brake line still good.

No, the car was under warranty until then, the brake line started leaking at 96k miles, Yes, my previous 9 Benz's had copper nickel brake lines, never had any brake line issues despite owning some for 16 years
