I'm guessing you haven't coded them? They will flicker until you can code them and tell the car Xenons are fitted

They need coding buddy, your car has been coded to run with halogens, it now needs to know it's running xenons, a simple check box in VCDS will sort the flickering.

Running the wire back to the CECM is totally different function and has no bearing on the flickering your experiencing.

Check the VCDS register for someone close by who might be able to help you out  :happy2:

I know this is an old post BUT I have just fitted xenons on my mk5 golf that came from a gti edition  30 and have the flashing lights. Can someone point me in the right direction for coding as I have tried with several vcrs and nothing seems to stop this happening I think I'm missing something. Thanks
