Sidelight/DRL leds

[Wakefield1989]

Car failed MOT, one of the faults was passenger side sidelight/drl light not working.
I've got 2013 E Class. Face-lift model with DRL built into headlamp.
I've managed to get into the headlamp and remove the led board.
Can't afford new headlamp so just wondering if it's something I can fix?
I've looked on Google but can't seem to find the led board that I think may be faulty. Want to try a new 1 and take it from there.
Any advice or help will be greatly appreciated!

One of the DRL's in my C Class stopped working, Mercedes said they replaced the headlight controller, was about £250 I think. Did not need a new headlight.
