CLA 45 xenon headlight problem

[cclassrob]

Hi all I i have a 2014 CLA45 AMG the drivers side headlight has been developed a fault where the car is displaying the following faults dip beam failure/ park light failure/ DRL failure / indicator failure. But everything was working then the whole thing stopped working. i replaced the xenon control balist module (that was full of water) and the DRL control module. the head light is now working again but the car is still displaying the same faults even after clearing all the fault codes with a snap-on OBD reader. is there any thing else that needs replacing?
