DRL LED flickering
After work today i noticed my passenger side LED DRL started flickering,
it doesnt shut off but you can see it go slightly dimmer than normal then back to bright, its very subtle but after looking at my driverside it was only one side.
it was more noticeable when i put a black object in front where you can see the flicker in the light output from the DRL.
anyone else experience this before? if so anyone know what's up?

Funny you should post that, I noticed the exact same thing on my W205 the other evening when park up in front of my dark blue garage door...

The DRL, like many LEDs use Pulse width modulation (PWM) to reduce thermal load and prolong life of the diode. If you get visible or inconsistent flicker (different to strobing) you probably need the controller checked or replaced.
