I tried searching and haven’t been able to find an answer. Looked through the fuse diagrams and still nothing. Ran obd11 and received two faults in ‘central electrics’:

Supply for Left LED Parking Lamp/ DRL Module
Electrical error in circuit

Terminal 30 left
Open circuit

I have a 2014 a6/c7 premium plus 3.0. About a month ago I had to change my left ballast. Last night nothing works on either headlight other than the right side DRL. I checked the fuses in the fuse box under the steering wheel and one was blown. I changed it and that one blew. Checked for water intrusion and did not find any. A mechanic I know suggested I change the relay but neither him nor I could figure out the location of the exact relay. Was hoping someone could help me figure the exact location of the relay for the headlights and if at all possible which relay it is? On the audi part store I see 4H0951253A/646 as the only relay that mentions anything about a headlight but I dont know if that is it for sure and if so where the relay is located. Thanks for the help in advance and love everyone always contributing.
