1) no but you should get the coding done correctly. It's not all for the error light when it comes to the headlights. Do you research on where locally will do VCDS coding for you. Make sure you bring them the exactly and correct coding instructions.
2) the LEDs are on the parking light circuit. They are on when low beam and high beam is on. They are not on (as standard) as drls. You can code using VCDS to have the LEDs as drl but you will then not have then on with low and high beam. You add a piece of wire (referred to as the jumper wire) into certain pins on the cars headlight connector block to enable the LEDs be on as drls and also on with low and high beam. You need to code correctly for this too. You get the bit of wire anywhere. There is no specific type. Read through the many threads in the forum for plenty of details and installation instructions on all of this.
I will keep them for when I have problems with the replicas down the road.
this may be stupid question, but how do we aim the lights? and if so is it possible to aim it through vag com?
thanks you sir.There are two plastic screw tabs on the housing. One controls up and down, the other left and right. Not possible through vagcom as far as I know.
