2017 C300
I noticed that my right DRL turn on faster than my left (or my left is turning on slower). I saw this when I was unlocking my car in the dark from a distance. It is quite obvious and looks like the car is winking. When the DRL's shut off, I also see the the right DRL turn off faster than my left (could be the other way around, need to double check).
During normal operation, both DRL's appear to be the same brightness. Both turn signals are synced and operating normally. Main LEDs look normal too.
I assume that the control module is faulty and that one of the DRLs modules can't handle the startup current maybe.
I'm still under CPO warranty so I was thinking about bringing it in, but wanted to gauge the forums to see if anyone else had this issue? Any thoughts?
EDIT: Also a 2017 C300.
