Guys, quick question for anyone that installed aftermarket facelift type headlights on their CLA (not OEM).

Just installed a set of aftermarket LED facelift look headlights on my 2016 CLA. I initially had bi-xenon with led DRL/Signal (top picture).

Install is pretty straight forward. The issue I'm having now, is I'm getting alerts as if the bulbs are out on each light for everything (drl, signal, low beam, high beam). I'm assuming it's a pin, wiring issue, coding issue, are all combined.

The lights work properly (except the high beam, which turns on then off and the error pops up) and the signal alert inside the car "blinks" super fast even though outside the signal blinkers are blinking normal.

Any inputs from anyone that installed similar headlights ? Was it a straight swap or did you do anything different?

Can anyone help with coding or wiring info?

Thanks everyone!
