2010 e550 coupe right turn signal intermittent

I just noticed that my cars front right (passenger) turn signal is only working intermittently. It doesn't even give an error message on the dash. I tried to change the bulb but it doesn't even look like I can access a bulb for this thing does anyone know how to fix or change this bulb?

I cannot even find where the bulb is located but I think it is a led that is integrated into something and not even a bulb.

Bi-Xenon turn signal not replaceable only low, high, and cornering lamps. Check connector & associated pins if fine you will need to have someone pull fault codes using Xentry (MB diagnostics) to identify problem could be lamp unit.

Damn nothing is easy on this vehicle. I am not even sure where a connector for the turn signal would be not sure why they didn't just use a bulb.

I meant headlamp connection. See if you reach it through fender liner to circumvent bumper.

Oh I'll give that a look. I am wondering if it may have something to do with the side marker light that is flickering and giving me an error. I doubt they would be on the same circuit but that is the only error message I have. Also just received the car back from the dealership for a completely unrelated issue and this of course happened after their release... It shows they bought a fuse and I wasn't sure what for, I am wondering if they were aware of this (or even caused this) and tried to resolve it. Hoping to resolve it myself as they aren't the most competent dealership.

Details should be on invoice, discuss your concern with the service manager.
