Hello Guys.
I own a Audi a4 2013. I was using the halogen headlights, when i bought the car it was in Halogen, and yesterday i decided to buy the Bi Xenon Lights.
But now i am having some problems with an eletronics on car.
The dealer changed the lights, the led lights are working perfectly fine, and they look so great now .
But the problem is , that now none of interior lights isn't working, also in the speedo mater its not so light what it was before, if i want to put more brightness nothing happens. Also the back light when i put on R isn't working now.
I changed today inside the headlights, a disk ( looks like an hard disk ) and put a new one, because the one that i had it wasn't supporting the jacks to put the Xenon lights. So When its this one, i am having all of these problems.
Also the Start Stop, is not working, i can't turn it off, it's always on now.

Anyone knows how can i remove all of the glitchs that are now in my car?
And sorry guys, my english its not good.
