I installed the Mc Culloch HID 10000K system on the 2006 AUDI A4 2.0T and looks great. However, once a while (like 5%-10% of the time) the lights start to flicker. It takes several times of try when this happens to get the HID to work (I turn on/off engine and on/off lights), then it gets working. Do anyone have a solution to where I can get this on 100% of the time without flickering?

 

Hi I had that problem as well check the connections and that the bulbs are seated correctly and that you havnt accidentally damaged the ceramic part on the Hid Bulb when you located the bulb as this is very fragile
Ive had to take my HIDs out of my 2006 A3 as its stopped my wipers working and is telling me that my autolights and wipers arnt working so its going to audi to have the fault fixed hopfully so best of luck
