hello folks,ive a strange issue with the drivers side headlight,i changed the bulb last monday as it had gone.ive now got the light staying on constant high beam,i switched  the bulbs thinking it was a faulty bulb but its still high beam so its the headlight unit thats the problem i think .its a lucas D3S bulb.anyone got any ideas what the problem could be?

hi jason,its just the one headlight.

it a 2014 a5.

no jason theyre the original headlights,i had a good check and all wiring seems fine,i checked all the fuses too,

ill check it again tomorrow in the daylight, thanks for your advice jason

its definitely worth a try! thanks again

just an update on the issue with the headlight,after 3 weeks of trying various things i gave the car to an auto electrician who said the unit was not repairable so i bought a new headlight from motorfactors who i always use,it cost me 730 euro.audi wanted 1450 for same unit!! anyway ive it fitted now so all good again.

by the way,these are very hard to get in breakers here in eire and i tried a few in the uk too but appearantly this is a fairly common problem on the A5.Greg
