i just got my HIDs installed on my 2003 audi a4 1.8t. i ordered them from ddm tuning there the 35w 6k slim ballasts and i researched before i bought and said no relay harness was neccescary so i didnt order it, i got them installed and they work fine however when i turn my lights on when the car is on my esp abs and parking light all come on, if i turn them on while moving my speedometer goes to 0 even though im moving, im thinking there getting to much power cause when i first turn them on theyre really bright then they dim down and brighten up again. the only thing i can think of so far would be to disconnect my battery a couple times to reset the cpu and see if that helps, anyone have anyother suggestions?

 

the ballast is to close to ur abs module. ITs causing a ground interfernce when it powers on. try relocating ur ballast on the drivers side i believe i might be wrong and the prob should go away. does it happen everytime u turn it on or once in a while.?
