I am in need of a diagram or the location of the Headlight relay

 

There aren't any. Power goes from the battery to the switch, through fuses, and to the lamps. Full headlight current runs through each component.

 

I'v had this problem twice now,and the new switch is only 2 yrs old.So I'm going to wire my head light's on there own switch an fuse.I'v had to do this to the ignition cause of the constant ign problem.I put A push button to start the vehicle instead of the key,just gotta make sur you lock the door when left alone.securty still work's so I'm ok with it.And I'm confident this same system will work for the head light's,beside's there R 3 empty spot's on the dash where the seat warmer's R,so should look pro.Some may say I'm destroyin A great car,but it work's,an I'm saving hundred's,an able to keep sporting my most fav car ever.If any body need's any advice,hit me up.Or just pay the dealr...Lot's of lov to AUDI....

 

FIXED !!! It was the ign again.This time I made sur it wasn't going to happen again.If anyone one need's any adv,hit me up.
