PART NUMBER; CK5219C164DN CK52-19C164-DN. IT CAME OUT OF A 2015 L405 AND HAD A VERY SMALL AMOUNT OF WATER INGRESS. I’M 100% SURE IT WILL BE A EASY FIX FOR SOMEONE WHO HAS KNOWLEDGE. HAVE TAKEN PICS OF THE INSIDE BOARDS AS HAVE HAD IT REQUESTED, (SEE PICS) WHICH MAY HELP A TECH. ANY QUESTIONS PLEASE ASK.
